Re: [beagleboard] Connecting BBB UART to another UART device
The serial debug port on the beaglebone black *is* a UART interface. That is, RXD/TXD + GND only. You should be able to technically use this with your RFID device, *however* it may also be possible that uboot by default may cause issues, or perhaps damage to your external device at powerup / boot. It should also be possible to configure uboot to play nice with your hardware. Probably the best / easiest way would be to use one of the other UARTs / set of pins.

This RFID module has the following electrical interfaces: UART with 3.3/5V logic levels from 9600 to 921,600 bps; USB 2.0 full speed device port (up to 12 Mbps) I already tried connecting it through USB but 'lsusb' and 'dmesg' shows nothing. So now I wanna try to connect it to my BBB trough UART (no USB is involved here). That is, my plan is simply use 3 wires (GND, RX, TX) to connect one device to another since I think both UART interfaces are compatible, right? Or am I missing to verify something to ensure they are compatible (both are TTL)? My question is, what is the simplest way to physically connect this device to BBB's UART? I want to know if would it be possible to use the serial debug header? That is, is this header a UART port? Or I must configure and use some of the P8/P9 pins? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

BTW you have never tried to code pages and pages using just VI probably Any person in their right state of mind would not use VI, unless you are writing short programs (like shell script), or very simple applications. Renounce to auto correction, color syntax, auto completion, and a ton more of functionalities, when you are coding millions of lines, is not different from running win 3.1 on a modern computer :) As much as I love terminal, there are things that are not feasible without a good text editor with plenty of functions; without even mentioning the pros of a real IDE, when you need to debug and such.

Dear users, I'm trying to get the LI-5M03CS (Aptina MT9P031) on BB-xM Rev C configuration running with Debian. First I tried some newer kernels but the FDT based boot isn't fully supported yet (or at least this is what I think after some reading) Then I cloned the git://github.com/RobertCNelson/stable-kernel.git build scripts, v3.9.x branch, selected MT9P031 in menuconfig and build the kernel. Then I cherry-picked some patches from Laurent: git remote add pinchartl git://linuxtv.org/pinchartl/media.git git fetch pinchartl git cherry-pick b54ece2d97c244416e3239f0a0d2a665fe1c152a git cherry-pick bca60770d38a41bab4b69c93cbbe3d79c1443f80 git cherry-pick 58ee8629ebc528b629dac36e5e5c67dffeecd2fa Then recompiled and installed the kernel on a SD Card which was previously installed with RCNs debian netinstall. After cloning, compiling and installing media-ctl and yavta im able to get images with sudo media-ctl -r -l 'mt9p031 2-0048:0-OMAP3 ISP CCDC:0[1], OMAP3 ISP CCDC:2-OMAP3 ISP preview:0[1], OMAP3 ISP preview:1-OMAP3 ISP resizer:0[1], OMAP3 ISP resizer:1-OMAP3 ISP resizer output:0[1]' sudo media-ctl -V 'mt9p031 2-0048:0 [SGRBG10 1280x1024], OMAP3 ISP CCDC:2 [SGRBG10 1280x1024], OMAP3 ISP preview:1 [UYVY 1280x1024], OMAP3 ISP resizer:1 [UYVY 1024x768]' /usr/sbin/yavta -f UYVY -s 1024x768 --capture=3 --file=$(pwd)/img#.uyvy /dev/video6 gm mogrify -size 1024x768 -format jpg *.uyvy but the first image is a magnified version of the following 2 images (all 3 have 1024x768 Pixels) After all this trialerror process I really wonder what would be the best way to get this camera running on Debian.

Re: [beagleboard] BBB + PREEMPT_RT
I did a test using the latest kernel from https://github.com/beagleboard/kernel/blob/3.8/configs/beaglebone and the kernel configuration I posted this morning. To load the cpu I used stress --cpu 1 cyclictest -l1000 -m -n -t1 -p99 -i400 -h400 -q. I have attached the output of cyclictest and an image with the latency histogram. The maximum latency is now at 262 µs. However, only about 0.2% of the samples are at t=36 µs. It is clear that a kernel with the simple PREEMPT option is not as good as one with the PREEMPT_RT option. But it is definitely much better than a default kernel without any preemption enabled.

What exactly is the difference between these repos? The default kernel configuration for kernel 3.8 from https://github.com/beagleboard/kernel is at https://github.com/beagleboard/kernel/blob/3.8/configs/beaglebone. In order to allow people to build a PREEMPT capable version we could simply provide a second kernel configuration. The name could be beaglebone_preempt. This way you wouldn't have to change the default configuration. On the other hand this would allow people to quickly evaluate the PREEMPT version and have at least some basic determinism. I have attached my modified kernel configuration. I am currently doing further tests. Am Mittwoch, 26.

Re: [beagleboard] Connecting BBB UART to another UART device
Thks for answearing! So uboot (the bootloader right?) might send bad commands to my device... well, can it really damage my device? I am just guessing ...

[beagleboard] Re: Connecting BBB UART to another UART device
The debug UART has both the uboot software behind it on boot, and later a linux serial console. During boot, if your device emits any characters, this will trick uboot into putting up its menu and hanging the boot process. It will be waiting for you to make a menu choice and your device will know nothing of it. Assuming you miss that one second window, plus all the time preceding uboot coming up under power where the uart's fifo will be filled, then you will clear uboot. But this is too much risk. The next phase of the boot has linux hosing its console output to the same debug port, and depending on the linux setup, you may have a serial console come up on that UART also. I do here. So the debug uart port is difficult to use for anything but debug. Use another UART. The device you describe may be using TTL serial, you did not mention RS-232 levels. This should be confirmed. If TTL, your device may still be at a voltage which is too high for the beaglebone to handle. Check the datasheet for 5V compatibility. I doubt its acceptable. If your device is assuredly TTL at 3.3V then it will probably work hardware wise by just hooking up the device, crossing TX with RX and tying GND to GND. The 3 wires you say. Then you have to PINMUX in the UART's TX and RX pins, or pick a UART you know is already pinmuxed out. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

libsoc has an implementation that will allow you to count interrupts by

[beagleboard] AM335x Device Tree Overlay
Hello, I'm using Yocto with [meta-ti] to create images for the Ti's AM335x EVM Starter Kit or a Beaglebone black (linux-ti-staging 3.12.10) Since last days everything went perfectly fine, but I've now some issues with the device tree. I created a device tree overlay (dtbo file) to enable SPI0 and now I'm looking how can I load this overlay during the runtime. I saw that the beaglebone team created a capemgr system to load dtbo dynamically (based on the I2C EEPROM data of the cape). My question is, how can I load my overlay on my linux who didn't implement the capemgr... Is there a standard way to do that ? It should be possible I guess, but I'm not a device tree specialist.

I guess, I should have realized that the filesystems get mounted only *after* the DT overlays are loaded.

But when I try to get it installed automatically via *capemgr.enable_partno*the kernel refuses to load it. The output of dmesg | grep capemgr after the overlay is installedhttp://paste.ubuntu.com/7036119/. You can see that it was not loaded on startup, but no reason seems to be reported. It did load successfully when the system was fully operational. Here is the full dmesg http://paste.ubuntu.com/7036139/. I tried using the priority setting ( *capemgr.enable_partno=BB-UART1,cape-bone-sundvi:00A0:10*), removing other overlays, etc to no avail. The HDMI drivers are disabled so there shouldn't be a conflict. The stock DVI cape cape-bone-dvi-00A0.dtbo seems to autoload without any apparent problems). What is really strange, even when I simply copy the original cape-bone-dvi-00A0.dtbo into another name (cape-bone-sundvi-00A0.dtbo), and specify this new name in the uEnv.txt, it no longer auto-loads! The *very same binary file*, only with another name. So the name of the dtbo seems to make a difference. I thought maybe the overlays must be listed in the main DT, in the list of capes. But I don't see the BB-I2C1 or BB-UART1 listed anywhere, and they load with no problem. I am sure it's something simple that I missed, but I am really having a hard time seeing what it is.

[beagleboard] Re: AM335x Device Tree Overlay
I am not an expert, but I would guess that if your system didn't implement capemgr, you won't be able to load device tree overlays. I would assume the capemgr would be an integral part of all kernels above 3.8, but I may be wrong. If you still use the device tree, you can edit the am335x-bone-common.dtsi or am335x-boneblack.dts directly, and add the appropriate fragments from the overlay source into the appropriate stanzas. Then recompile the dtb, and copy it onto your board. Otherwise you would have to implement/enable the capemgr.

I created a device tree overlay (dtbo file) to enable SPI0 and now I'm looking how can I load this overlay during the runtime. I saw that the beaglebone team created a capemgr system to load dtbo dynamically (based on the I2C EEPROM data of the cape). My question is, how can I load my overlay on my linux who didn't implement the capemgr... Is there a standard way to do that ? It should be possible I guess, but I'm not a device tree specialist.

Re: [beagleboard] Re: Custom DT overlay only loads at runtime on 3.18.13-40
Yeah, I was thinking about something like this. But since I am making a video controller overlay, it is better if it had been loaded at kernel initialization, and not as part of the init scripts. I'd like the display to be available to show some kernel startup. So I will either just overwrite the cape-bone-dvi-00A0.dts with my own stuff (and make a custom Sunhillo-only patch), or will add a new overlay to KERNEL/firmware/Makefile. It seems that a lot of people got confused by this issue (long discussion here https://groups.google.com/d/topic/beagleboard/Iem_mHknIUM/discussion). The problem is, the available documentation for 3.8 kernel seems to imply that the /lib/firmware overlay files are available for startup load, so it would be helpful if qualification was added.

[beagleboard] A project on enhancing the Beaglebone beginners experience(GSoC?)
Hi, I am Tarang, a student looking forward to improve the out of the box beaglebone experience. This will mostly involve improving the current bone101 webpages with additional demos and improvement of the current demos. This is the set of pages that people are greeted when they go to 192.168.7.2 on connecting their beaglebones to the computer through USB. I plan to include examples which help the user in using the bbb with different hardware and electronics. Along with this I plan to develop examples and wrappers for interfacing with the web. I hope to do the above work as part of a GSoC 2014 Project. I had previously emailed to the beagleboard-gsoc mailing list describing the Idea and have received some feedback as well. The aim is to enrich the out-of-the-box experience for a bbb-beginner. I have linked the above mentioned conversation from the group here - https://groups.google.com/forum/#!topic/beagleboard-gsoc/0JpdUsSvuBQ Do have a look at it! I am still in the process of improving the basic idea and making the work plan. *It would be great if people in beaglebone community can give suggestions to the idea so as to improve the project. * *Also, I am looking for possible mentors for this project, who could guide me for a GSoC 2014 project.* *Do let me know your views and suggestions on this idea!* Thanks, Tarang Shah On Wed, Feb 26, 2014 at 7:28 PM, Jason Kridner jkrid...@gmail.com wrote: On Tue, Feb 25, 2014 at 12:07 AM, Tarang Shah taran...@gmail.com wrote: Hi, This is Tarang.

I also have knowledge of programming microcontrollers, linux and 8086, MIPS assembly which will help me(directly or indirectly) in contributing to beagleboard. I was going through the Ideas page and the current projects related to them. Out of the projects I liked, I want to ask some things on the following project, BoneScript web pages with live-running examples and documentationhttp://elinux.org/BeagleBoard/GSoC/Ideas#BoneScript_web_pages_with_live-running_examples_and_documentation I was looking at the bone101 pages which has the bonescript guide. The side bar at that page already links to certain demos which are mentioned in the Ideas wiki page. I have tested some of those demos and they work nicely on a beaglebone black. I was thinking of extending the bone101 demos to interact with the Internet(twitter, facebook etc.). Great! The Internet can serve as both an output(as a tweet, status, picture etc) and as an inputs( User location, tweets/posts by a user whom you follow etc.) for the beaglebone which will be interface with sensors and actuators. This would enable beaglebone to be a powerful internet of things device more accessible to everyone. Doing something with interacting with the web as part of the out-of-box-experience seems great to me. This has come up in discussions with Adafruit, element14 and others as a desired feature. It seems to be it should be implemented as some kind of wizard that walks you through the various steps and then leaves you at the end ready to play with the API. I am currently getting acquainted to bonescript to write my own bonescript programs. I wanted to know if I can propose a GSoC project in this domain? Of course you can propose it. Ideally if you could attract another mentor or two that would be best. Hanging out on #beagle and #beagle-gsoc is a good way to meet potential mentors. Also if possible, do let me know of things that must be done on enhancing the already existing demos as well. I think there isn't a clean enough presentation of what they are trying to show in a way that makes a novice feel comfortable putting them together. The current connect-status-bar is the most confusing aspect right now, especially because it leaves people unsure about what is actually happening. Making the connection between the web page and the board more explicit --- and making it clear where what code is running --- would really be helpful. Also It would be great if you could give suggestions and other similar projects which I could incorporate in my draft proposal. I also have knowledge of assembly and looking at the Ideas, I think I contribute to the Virtual Machine for PRU project too. It will be great if you can provide some pointers towards that project too. There were a few pointers on the wiki page. Can you check those out and come back with questions? Thanks a ton, Tarang Hi, Thanks a lot for the feedback! On the basis of that feedback, I want to propose some additional information regarding my project

Hello Porkupan, Thank you for your fast answer ! I searched in the meta-ti linux-ti-staging kernel (git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git), and I didn't found it.

[beagleboard] Linux when moving from beaglebone to custom AM335x board
We have been prototyping on beaglebone black for about a year and are building a custom AM335x board for our product. We plan on using the WL18xx WIFI/BLE chip and a few other TI peripherals. I have been assuming we will have to use the older 2.6? TI-supported linux instead of the 3.8-bone kernel we're using now.. any recommendations on this? Does TI have a newer linux distribution that is supported? Is 3.12 ready?

Re: [beagleboard] Re: Coding with C/C++ directly on Beaglebone, via IDE?
Cross compiling is really as simple as downloading a Linaro toolchain, and just setting up the toolchain binary paths in an IDE. Even on Windows. Then on Windows you can use Visual Studio, Eclipse, Code:Blocks, or even use the toolchain directly via comandline, with an editor like notepad++, or Sublime text. Notepad is even possible, but I think that any reasonable developer will know that notepad is not really an option. Personally, I use Code:Blocks for project management, and cross compiling( Via Linaro GCC). Sublime text as my main editor, and a directory shared via Samba, which is them maped as a network drive in Windows.

Re: [beagleboard] Re: BBB is a great home server but printing is a challenge
I will try to help but I did this some time ago and being an old man, my memory is failing me. Using CUPS I can print to my HPLJ printer from my BBB but not from Windows. Windows seems to need a driver to print to a networked printer and it does not have one for the HPLJ 1012. A friend had no problem printing from an iPad. I installed CUPS probably with apt-get install. I have CUPS version 1.6.2. I also installed hplip. I plugged my HPLJ 1012 into a USB port and did lsusb. It listed Bus 001 Device 005: ID 03f0:0d17 Hewlett-Packard LaserJet 1012. From my Windows PC, using Chrome, I connected to CUPS on my BBB with http://bbb:631 where bbb is my BBB and 631 is the port used by CUPS. From there it's easy. I just did Add printer and my HPLJ 1012 was listed so I selected it. I selected HP LaserJet 1012 - CUPS+Gutenprint v5.2.9. I can print from the console on bbb with lp file. If your printer is connected via USB, you probably need some driver for it. When it is plugged in, try lsusb. If it is not listed, try to find a driver for Ubuntu and ARM.

Re: [beagleboard] Re: Connecting BBB UART to another UART device
I do not know that uboot would / would not damage your UART device, but I also do not know that it will not. Then as dickelbeck mentions above there are other potential pitfalls. As for the Linux console, this could / should be configurable via inittab, but uboot I have no idea exactly what needs to be done. This would most definitely need source editing and binary recompiling. On Wed, Mar 5, 2014 at 7:59 AM, dickelbeck d...@softplc.com wrote: The debug UART has both the uboot software behind it on boot, and later a linux serial console. During boot, if your device emits any characters, this will trick uboot into putting up its menu and hanging the boot process. It will be waiting for you to make a menu choice and your device will know nothing of it. Assuming you miss that one second window, plus all the time preceding uboot coming up under power where the uart's fifo will be filled, then you will clear uboot. But this is too much risk. The next phase of the boot has linux hosing its console output to the same debug port, and depending on the linux setup, you may have a serial console come up on that UART also. I do here. So the debug uart port is difficult to use for anything but debug. Use another UART. The device you describe may be using TTL serial, you did not mention RS-232 levels. This should be confirmed. If TTL, your device may still be at a voltage which is too high for the beaglebone to handle. Check the datasheet for 5V compatibility. I doubt its acceptable. If your device is assuredly TTL at 3.3V then it will probably work hardware wise by just hooking up the device, crossing TX with RX and tying GND to GND. The 3 wires you say. Then you have to PINMUX in the UART's TX and RX pins, or pick a UART you know is already pinmuxed out. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Only the orange screen from u-boot then no signal. I've tried installing the Graphics SDK release 5.01.00.01 from TI's website. Installation appears to go smoothly but the pvr service fails to load. Do we know what version of Linux the SGX libraries will work with? Does anyone have an idea of what direction I need to go in to achieve this?

Re: [beagleboard] Powering the BBB
Because the regulator is going into thermal limit due to excessive heat dissipation. Make the 11.7V supply say 8V and it will run longer. The hole in the tab of the regulator is for the heat sink. Now, if the regulator is putting out 7V, then it could be the board.

[beagleboard] BeagleBone Black Vdd Power
Using the Beaglebone black Revision A6A. I powering it with supplying 5V to the Vdd pins. The 5V is coming from an adjustable regulator with an enable line. Also I have a 10uF tantalum capacitor on the regulator's output to avoid sending a noisy 5V. When that enable line goes high, the beaglebone black does not power on all the time. Sometimes the BBB boots properly. However, instead of powering on sometimes, it seems that the power management chip on the BBB is switching Vdd to no load. I still have a similar result with different tantalum cap values. What is the state of the switch in the power management chip on a rising edge of Vdd?

The PMIC is sensitive to slow ramping power supplies. A 10uF capacitor is also a little small.

I wonder How to work pullup pinmode at input in software. http://beagleboard.org/Support/BoneScript/pinMode/ I want to pull up P8_31(GIPO_10) as Input 、but it effect noting. 1.b.pinMode(P8_31, b.INPUT_PULLUPhttp://beagleboard.org/support/bonescript#input_pullup ); 2.b.pinMode(P8_31, b.INPUThttp://beagleboard.org/support/bonescript#input_pullup, 7, 'pullup'); Both are in same result and P8_31 never pulluped. Of course http://ejje.weblio.jp/content/of+course when I connected a 10Kohm resister between P8_31 and VDD3V3 , It pulluped and work fine. I want to omit this resister. Many chips (PIC AVR etc..) has software pullup mode and no need to connect extra resister. But In BBB It doesn't work?? Always need extra resister? My BBB's info: *Your board is connected!* BeagleBone Black rev 00A6 S/N 4613BBBK1318 running BoneScript 0.2.2 at 192.168.7.2 I want some help, Please. Thanks. P.S. I know in BBB it is limited 4mA or 6mA for GPIO current. My question is total current limitation in BBB. Is there any limitation for total current? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

The 5V is coming from an adjustable regulator with an enable line. Also I have a 10uF tantalum capacitor on the regulator's output to avoid sending a noisy 5V. When that enable line goes high, the beaglebone black does not power on all the time. Sometimes the BBB boots properly. However, instead of powering on sometimes, it seems that the power management chip on the BBB is switching Vdd to no load. I still have a similar result with different tantalum cap values. What is the state of the switch in the power management chip on a rising edge of Vdd? Has anyone else had a problem powering the BBB with Vdd? I'm doing almost exactly what you're doing except that my regulator chip doesn't have an enable line. So far it has worked exactly as it should, applying power by plugging the 5v supply into pins 1 and 3 on P9 just powers the BBB up as normal. I only have a .33uF tantalum on my regulator input and nothing on the output. -- Chris Green · -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] How can I omit pullup resister.
Check the datasheet. The pull up may or may not be small enough depending on what it has to pull up. The current is the max the pin can do. In other words, that is who large the pull up actually is. Turning on all the weak pullups isn't going to strain the total current of the power supply which is the real limiting factor. And there aren't that many pullups you can turn on any way as most of the signals are used for other things on the board..

[beagleboard] How to write attachInterrupt in BoneScript in details.
Hi, forks!!
I have some questions about attachInterrupt.
I saw the topic
attachInterrupt contents called on startup and stop without event triggered
https://groups.google.com/forum/#!topic/beagleboard/bhacfUnNJYM
Q1:
I think one of solution is check actual button has pushed or not.
b.attachInterrupt(inputPin, true, b.FALLING, interruptCallback);
function interruptCallback() {
if (b.digitalRead(inputPin)===1) return; // Is the real button pushed?
or not?
But in this case, the function interruptCallback tightly depend on hardware
,so I can't reuse it call from another functions (for example WEB interrupt
logic).
It seems not good solution.
Is there any solution more smart?
Q2:
http://beagleboard.org/Support/BoneScript/attachInterrupt/
I guess the result of handler can determine to interruptCallback execute
or not.
But when my function my*handler *always return true, interruptCallback never
called...
b.attachInterrupt(inputPin, myhandler, b.FALLING, interruptCallback);
function myhandler(){
return true;
}
Could you tell me what is wrong, Please!
Thanks.

Re: [beagleboard] Coding with C/C++ directly on Beaglebone, via IDE?
These are commodities added on top; the original VI or VIM do not have all of these features. If you log in into a standard Unix box, you won't have that. Technically you can write shell script that allow you to compile and link directly from VI, but is more work than expected...it was not made for that after all. Not saying that you can't do it; but that it is a pain to do it for big projects. I use VI all the time for any small project, but try to write something like a full size application and you can see that is not feasible. BTW you refer to text editors preference, not IDE, since VI is not an IDE. I agree that each person choose their own, same goes for the IDE :) For example I still love DEV C++; does all that I need and I wish that there was a version for Angstrom...and that's an ancient IDE, but it is lightweight and decently fast. Most people do not need the ton of features that big IDE gives you, like VS.

Re: [beagleboard] Re: Coding with C/C++ directly on Beaglebone, via IDE?
I don't see anything wrong.in this world nothing is wrong (other than the attitude), there is what is right for someone and what is right for most of the people. In 15 years working as programmer, I have NEVER experienced a single developer using VI for anything other than modify server side files (either config, daemons, apache config files), or to create quick shell script to automate some process. I've been in plenty of companies, where there were awesome people that had 40 years of experience, that were so kind to show me how they do their jobmost of them avoided intentionally VI when they had the chance, because they had to work with it in the past, since there was nothing else :) Strange enough, nobody loved it, while writing applications of a certain size. If someone likes it as text editor, so be it, but I would not go around saying to others that they are wrong, just because they don't see it in the same way. Conflicts are born because someone think that he/she has the right to be right, while the others are wrong. Especially in CS, there is more than a way to do anything, so the right or wrong is really a matter of personal opinion. Then again: Emacs and VI are text editors, not Integrated Development Environments; for the same reason that a VW beetle with a Porsche engine is not a Porsche, a text editor with IDE functionalities is not an IDEit can be used for that purpose, but there are a ton of other easier and more reliable alternatives; which means that the use of this or that method is purely discretional and based on personal preferences. The original topic was is there an IDE for the BB, to avoid cross compile?, unless I am mistaken.

Re: [beagleboard] Re: Coding with C/C++ directly on Beaglebone, via IDE?
Did you try with Eclipse? It is multi platform, and there is a nice youtube tutorial video that show how to set it up for the BB. Quite simple to cross compile, but not possible on the BB itself; Eclipse just sit and cry if you run it on the IDE, even without loading the full desktop (tried to just start X11).

[beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test
I use a Mac and despite the latest version of HoRNDIS fixing issues with Internet Connection Sharing, getting on the WIFI at home makes getting my BeagleBones on the network much easier, further making grabbing new packages with 'sudo apt-get install' much simpler. Drivers and firmware for many common USB WiFi dongles are included, so be sure to report any that you find missing. These latest images include the drivers for the popular UWN200 adapters provided by Logic Supply. To test it out myself, I uncommented and edited the wlan0 entry in /etc/network/interfaces (including replacing wlan0 with ra0), shutdown, plugged in the adapter and powered up the board again. I'm seeing the issue rt28xx_open return fail!, but I'm sure this is something we can fix in a few days and provide an updated image. I removed that adapter and plugged in an adapter I bought from Adafruit (and switched ra0 back to wlan0) and got the issue rtl8192cu:_rtl92cu_init_power_on():0-0 Failed to polling REG_APS_FSMCO[APFM_ONMAC] done!. Finally, I plugged in a TL-WN822N adapter I bought from Amazon and BINGO---WiFi!!! Anyway, getting reports on what adapters work and don't work would be really helpful at this point as we'll be trying to get a very full set of WiFi drivers included. Talking with the guys at Logic Supply, it's just a small goof in the directory location of the RT2870STA.dat file.

Re: [beagleboard] Powering the BBB
in hopes of explaining what is being talked around is this. You want 5V from 11V so there's 6V difference. Those linear regulators will give you the 5V at some current level(let's say 1A for simplicity). So you get 5V at 1A and that's 5Watts(5V*1A) but that 1A of current is also involved in that 6V drop from 11V to get you 5V. The energy/power wasted in that 6V drop is calculated by the current of your load( 1A ) times the drop( 6V ) which is 6Watts in the example. This is why Gerald is correct in his statement that the linear regulator is wasteful since in the example you only need 5W and have 6W of waste so have a total energy cost of 11W. A better solution would be a DC-DC converter and you can get those on amazon with free shipping from china(if you can wait) for less than $10. The take the input power turn it into a AC signal which can then be chopped and reassembled into a lower voltage with little energy loss. for example: http://www.amazon.com/gp/product/B008BHAOQO Doug -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Those linear regulators will give you the 5V at some current level(let's say 1A for simplicity). So you get 5V at 1A and that's 5Watts(5V*1A) but that 1A of current is also involved in that 6V drop from 11V to get you 5V. The energy/power wasted in that 6V drop is calculated by the current of your load( 1A ) times the drop( 6V ) which is 6Watts in the example. This is why Gerald is correct in his statement that the linear regulator is wasteful since in the example you only need 5W and have 6W of waste so have a total energy cost of 11W. A better solution would be a DC-DC converter and you can get those on amazon with free shipping from china(if you can wait) for less than $10. The take the input power turn it into a AC signal which can then be chopped and reassembled into a lower voltage with little energy loss. for example: http://www.amazon.com/gp/product/B008BHAOQO Doug The most important detail here is the 6W of waste heat. A linear regulator regulates the Voltage by generating heat. The heat generated in a linear regulator is measured in Watts and can be calculated as the Voltage dropped across the regulator times the current through it. From this discussion I understand that to be 6W (6V * 1A). The regulator will have a specification for the temperature rise from the die to case (or ambient) per Watt. A common LM340 in a TO-220 case, for example, has a 4C/W junction/case and 54C/W junction/ambient rating. In this example that means with no heatsink the junction will be 324C over ambient (54C/W * 6W). The 24V limitation is not the factor here, it's dissipating the heat. You will need a heatsink capable of disipating at least 17.6C/W to ambient just to keep the LM340 TO-220 from reaching its rated 150C limitation with an ambient temperature of 20C (20C + (4 + 17.6C/W) * 6W = 150C). At elevated operating temperatures you will need a better heatsink than that. I don't know what regulator you are using as you have not stated that publicly yet, nor do I know the maximum temperature for your application so I can't guess what size heatsink you will actually need. Short answer: Use a big heat sink or a switcher.
