Re: [beagleboard] Re: Change default state of GPIO pin
I found this thread on http://electronics.stackexchange.com/questions/94297/transistor-which-opens-circuit-reverse-transistor I think I will go for the solution from alexan_e, making a reversed circuit with two transistors. It only costs one transistor more. I have tried changing pull-up to pull-down with uboot, but that didn't work for me. Thanks for all the help!

You now have an effective voltage divider with a pullup / pulldown configuration. Fighting against the configured on-chip pullup is going to mean that to output a high you're going to need many times the drive current you would normally need as you sink current into that low-value pulldown resistor. Not sure what your threshold on the buzzer is but if the pullup is say 30 to 50K then to get a solid 10% default low on the pin you'd need a 3 to 5K resistor on the pulldown. That would be a 1.1 to 0.6mA load on the pin when it swings high. You're also burning 0.1mA when the pin floats since the voltage divider will always be present. That may or may not impact your design.

[beagleboard] libpruio (fast and easy D/A - I/O)
http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/pruio_logo.png A new library called libpruio is availble to support digital input and output as well as analog input on Beaglebone (black) hardware. It uses software running on a PRUSS to configure and control the devices - Control Module (pinmuxing) - GPIO 0 to 3 (digital IO) - TSC_ADC_SS (analog input) The API is designed for easy usage, but also for fast execution speed. No need for root privilegues or further device tree overlays (just a single overlay to start the PRUSS). It's compiled by the FreeBASIC compilerhttp://www.freebasic-portal.de/downloads/fb-on-arm/bbb-fbc-fbc-fuer-beaglebone-black-283.html, but also includes a wrapper to be used with C compilers. The package contains example code in both languages. Development and testing has been done on a BeagleboneBlack under Ubuntu 13.10.

Thanks for the registration tip / link, done. And thanks for your positive statement. I hope you find some time to look under the hood. Would be nice if you can run some of the pre-compiled examples and tell us your thoughts. The licences are LGPLv2 / GPLv3, so it could get in to the default image. I'd like to get some feedback and fix the major bugs, first.

[beagleboard] flashing eMMC
I downloaded the eMMC flasher image (images_BBB-eMMC-flasher-debian-7.4-2014-04-23-2gb.img.xz), put on it on a micro SD card (using dd), and tried the hold the boot button when powering on. Firstly I'm pretty concerned at this point that there is no easy way to know if it is really booting off the micro SD card or the eMMC. I had to eventually hook up ethernet and ssh in to figure out it was indeed booting off the debian linux on the micro SD card. The very vague instructions say that flashing is done when there is no LED activity, and they become solid. Very vague indeed. I have no idea why it is not getting flashed. I am doing the boot up sequence properly, it is indeed booting up off the micro SD, but all the lights are flashing randomly until about 30 seconds later when they all blink at the same time, and remain that way indefinitely. The vague instructions say 45 mins, not 30 seconds, and the lights should be all on but solid, not flashing. Should I be able to ssh into the device when it is flashing? If not then it is clearly not even trying to flash. If there was some documentation on how to check if the flashing is actually happening or perhaps some way to execute it.

Maybe Charles unterstud what you mean. Unfortunately I'm not an expert of DT. So maybe you can explain how I can use GPIO as usrLED? In the am335x-boneblack.dts are GPIO 21 - 24 for usr0 - usr3. But don know if they are activ and available. Cannot find these GPIO! I recommend that you always retain the previous responses as I don¹t recall what your original questions was. Anyway, in arch/arm/boot/dts/am335x-bone-common.dtsi, on line 30 you will find the pins used for the LEDs. If you want to move the LEDs to a different GPIO, then this is where you make that change.

Re: [beagleboard] flashing eMMC
If all of the LED's are flashing together then I believe there was an error while flashing the eMMC. Check the md5 on your eMMC flasher download to make sure there was no corruption.

Most of the hardware on the SoC defaults to off (powered down with no clock signal) until you explicitly enable it via loading it's driver.

Re: [beagleboard] BeagleBoard Data Acquisition Platform
How many people here are serious about making an ADC cape for the BBB? One thing we could do is create a wiki and do it as a group effort. It sure worked for Linux. I myself would like a bank of ADS8344 chips - On the BBB that would entail sending and receiving digital signals on the GPIO. And - I hasten to mention, I am not an ee designer - AI SW is my thing. - BUT I feel strongly that this project is easily do-able. So please leave a response here if you are interested in participating. Here are a few tasks: (I am mainly interested in ADC.): 1. get digital signalling protocol from ads8344 spec sheet (ti.com) 2. get code to IO the GPIO pins. 3. post some questions on ti.com forums - get intouch with adc engineer there. get her advice. 4. V ref circuit. 5. choose language, Python fast enough? 6. order chips and interface boards for SMD type. 7. solder chips. (easy) 8. connect to GPIO. 9. start sending signals and do a conversion. (ADC) 10. write SW to store values in data structures.

Then you need to build this new flat device tree and load it to your board.

[beagleboard] Re: flashing eMMC
Unfortunately I have no display. I do have a lapdock with mini hdmi, but when I boot off USB for power, the default installed image would disable hdmi output. According to blog posts I found at that time, it was doing what it was supposed to, as the system would go into USB host mode and assume you won't be needing the display. Since none of the procedure documents mentioned there would be any screen output during the process, I would assume there would be no output. If there was even a comment such as you can verify the flashing is actually occurring by viewing on display Thanks for the tip! It would have prevented me from bricking it :) I bricked the eMMC :). I discovered this by hooking up to the network, and SSHing in. It was clearly showing it was running Debian. So I rebooted without holding the boot button, it would also load into Debian. I thought perhaps it did upgrade the eMMC (because I did leave it for some time -- 60 mins plus), and booting up without pressing the boot button would result in booting into Debian. But in reality it was booting always from micro SD, because a) when I ejected the micro SD card and powered on, it would not boot at all (only power LED would be lit), and b) I noticed the / and /boot was mounting off the micro SD card rather than the eMMC. I shortly concluded that the flashing went bad, as after mounting the two eMMC partitions, I realized they were empty (with the latter being unformatted). So it looks like during the initial power on to flash, it didn't flash properly (aborted, etc), and it seems you only have 1 go at it, as subsequent boots of micro SD would simply boot up the system and not flash the system. Anyways. I couldn't find any way of flashing it from command line (no tools exist that I could find, etc). What I ended up doing was formatting the unformatted parition with EXT4, and then rsync to the eMMC the /boot and / off the micro SD card. Powered down, ejected the micro SD card, and booted up successfully into Debian from eMMC. I guess I'll blog about my issue so that its available online for others who run into the same problem.

Re: [beagleboard] flashing eMMC
I checked the MD5 and it checked out ok (I had used the bittorrent link to download). I 'dd'ed the micro SD card, and like the first time, would do a sync to ensure it completely imaged. Like I mentioned, I know it was booting off the card but simply not flashing the eMMC. Like my subsequent post pointed out, it did at least try at one point, as it corrupted the two partitions. The issue is, subsequent reboots off the micro SD card would not invoke the eMMC flashing, and there is no instructions anywhere on the procedure to manually force invoke the process. I ended up resolving it my manually rsyncing the filesystems over to eMMC.

Check the md5 on your eMMC flasher download to make sure there was no corruption. Then try re-flashing the SD with the eMMC flasher image and re-flash the eMMC.

Firstly I'm pretty concerned at this point that there is no easy way to know if it is really booting off the micro SD card or the eMMC. I had to eventually hook up ethernet and ssh in to figure out it was indeed booting off the debian linux on the micro SD card.

[beagleboard] PRU-ICSS external interrupt
Hi everyone, I am working with the BeagleBone Black trying to make the ADC and the PRU-ICSS work with each other for sampling an analogue signal. The issue that brings me here is a small-big problem I have with the external interrupts of the PRU-ICSS, basically it does not receive these signals. Although the internal interrupts work fine (PRU to PRU) and sending pulses to external hardware such as the host. In some few words the test program I am now running in the system configures the ADC to start sampling data continuously and generate a End_of_sequence interrupt to the PRU0. I have checked that this interrupt is being triggered correctly by polling the IRQSTATUS_RAW register of the ADC from the PRU directly, and checking the sampled data in the FIFO. (In fact this is also another way of bypassing the problem, but is not the most efficient nor elegant way to work with this device I think...) I also have this problem with the EDMA3 module, there is no interrupt from this device to the PRU-ICSS. But this is another issue, and I think is the same problem as the previous one. Here is the code (the important parts at least) I am running in the PRU-ICSS: Definitions: #define gmoADC 0x44E0D000 //Global memory Offset of the ADC First the ADC configuration: //CONFIGURATION ADC // == MOV MemPointer, gmoADC //Control register MOV r1, 0x0005 LBBO r1, MemPointer, 0x40, 2 //TS_CHARGE_DELAY //Set default value (1h)018C3040 //STEPCONFIG1. //AIN1 (Channel 2) (+input) //Single ended //VREFP (+ref) = 1.8 V //VREFN (-ref -input) = GND MOV r1,0x0001 // 0x018C3002 //After test last bit will be changed SBBO r1, MemPointer, 0x64, 4 //STEP enable register LDI r1, 0x02 //STEP1 SBBO r1, MemPointer, 0x54, 4 //STEPDELAY1 Set as default //Interrupt parameters //IRQENABLE: End of sequence MOV r1, 0x0002 SBBO r1, MemPointer, 0x2C, 4 Configuration of the INTC (PRU): //Global interrupt enable PRU MOV r1.w0, 0x0001 SBCO r1, INTCbase, 0x10, 2 //Enable host 0 int MOV r1, (0x|0) //(0x|Host_num) SBCO r1, INTCbase, 0x34, 4 //Map channel 0 to host 0 LDI r2.w0, 0x0800 ADD r2.w0, r2.w0, 0 //Add host_num to host map registers offset 0x800 MOV r1.b0, 0 //Channel number SBCO r1.b0, INTCbase, r2.w0, 1 //Map system evento to channel 0 LDI r2.w0, 0x0400 ADD r2.w0, r2.w0, SysEvent //Add system evento to channel map register offset 0x400 LDI r1.b0, 0 //Channel number SBCO r1.b0, INTCbase, r2.w0, 1 //Clear system event interrupt MOV r1, (0x|SysEvent) SBCO r1, INTCbase, 0x24, 4 //Enable system event interrupt SBCO r1, INTCbase, 0x28, 4 Now, if I keep polling the register IRQSTATUS_RAW of the ADC (and clearing the interrupt flag), the program works fine. But if I do the same but polling instead bit 30 of R31 well that is why I am writing this I verify this by getting the data from the PRU's RAM using the host process. I am running an Angstrom v2012.12 in a revision A5C BBB. Kernel version: 3.8.13. Someone has the same problem, knows some possible solution (appart from the polling)?...

If I would need more processing power, I would go for Odroid-X3. If I need availability for decades and processing power, I take a sip from Freescale imx6 bowl (Wandboard, UDOO, Riotboard, whatever). And going cheaper, there is still the RPi with its ridicolous board layout. But - I love the Beaglebone Layout with its cape support. Making own capes or BUYING someones other cape at my specific needs is the key strength of the whole Beaglebone ecosystem.

[beagleboard] path of least resistance to Debian
I am fairly certain that this has been answered but I have spent the last two hours perusing the Wiki, the website, and the forums looking for a definitive path to move my BBB from Angstrom to Debian.

I'd rather not have to boot up Windows if I can avoid it. (After all, we are trying to run linux and having to run Windows in order to do maintenance on a Linux system just seems ... wrong.) 4.

#1 Personally I would run from a uSD card to make sure it is what you want.

All the instructions I've seen are *NIX based, and I *DO* personally run Windows for my own desktop environment. #4 You would have to boot up via uSD to write out the eMMC I believe. You may want to consider dedicating a machine, or perhaps use virtualbox to have a Debian wheezy i386 support system. This really depends on how serious you are. As an example, I compile my own kernel based on Robert Nelsons instructions, and build a custom rootfs also based on his bare rootfs stuff.

Ok I stand corrected. I keep forgetting about armel and armhf differences ( mainly because I only use armhf ). I did also want to mention that in package form mono runtimes are rather limited for armhf. But I also have seen this github guide Robert mentioned above.

I appreciate the response - but how in the world do you install a device tree? Been searching all over the place and find billions of references to how to compile one, but struggling with what to do with the one that is already compiled. Also - the very limited docs seem to indicate this is already installed The current Debian images have the required patches and will play audio normally. there are zero other docs to help someone that just wants to use this rather than become a linux guru.

[beagleboard] ANNOUNCE: New Machinekit Images and CRAMPS Design
I have been very busy lately and am pleased to announce the release of two new updates: 1) New Machinekit uSD images for the BeagleBone === This is a long over-due update to my Machinekit uSD card images. This image is based on the official BeagleBone Debian release from Robert Nelson, so all the BeagleBone specific additions (like node.js and USB networking) should work just like a regular BeagleBone running the factory Debian image. See the Machinekit page on my blog for details: http://blog.machinekit.io/p/machinekit_16.html I also have an (untested) eMMC flasher image available, which should allow you to run Machinekit from the 4G eMMC on the RevC BeagleBone. I would be happy to change untested to tested and known working if anyone cares to send me an acutal RevC board. I'm still waiting for either of the two I ordered to arrive. ;-) 2) Version 2.1 of the CRAMPS motion control cape The redesign of the CRAMPS board is now finished, and I have sent gerber files out for fabrication. As always, the design files are available on github: https://github.com/cdsteinkuehler/bobc_hardware/tree/CRAMPS/CRAMPS ...and design details, BOMs, and assembly instructions can be found via the CRAMPS page on the RepRap wiki: http://reprap.org/wiki/CRAMPS This version focuses on cost reduction and simplifying the V1.0 design, and I really like how it has turned out. I stopped restricting the design to minimal changes of the RAMPS-FD board and I feel the new Version 2.1 board really gets back to the simplicity that made the original Arduino RAMPS design so successful. I am also working on a 3-axis add-on board (the CRAMP3) which means you can have 9-axis motion control for those folks working with Stuart platforms or machines like Nicholas Seward's Sextupteron: https://www.youtube.com/watch?v=2kXdsU2bBp0 Once the PCBs arrive, I'll probably have some extra CRAMPS boards to sell for a nominal cost. Watch my blog for purchase details if you're interested in buying one. I'm really hoping someone will sell kits or assembled units once I've verified the new design works as expected. Contact me directly if you're interested, or just start building and selling them! It's an open design, I won't mind (really!)...but if you contact me, I can help with engineering support (like a production test program or approving alternate parts). -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] A simple cape to prevent power-interrupt corruption?
Yes, I did find those. From what I read, it seems that both aim at allowing the BBB to run when there is no mains power. In my application, I don't have a need for the BBB to maintain functionality when there is no power (other than battery). I'm simply interested in ensuring a safe shutdown sequence when power is removed. It seems from both posts that this has still not been addressed. These methods are focused on keeping the BBB running on battery power; however, when the battery discharges, I saw no discussion about an orderly shutdown occurring. I'm looking for an immediate, but orderly shutdown, and don't care about sustaining operation (beyond a safe shutdown) when power is removed.

Using debian for the beagle board Is there some kind of configuration that is needed to make this work? Or, is there any docs for this board (Rev B) that explain what needs to be done? Appreciate any help. aplay -vv file.wav Seems to do something, but no audio from either of the ports. What kernel version are you using? You need to install the Audio Device Tree BB-BONE-AUDI-02-00A0.dts You will find that here http://elinux.org/CircuitCo:Audio_Cape_RevB Regards, John thx e -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] A simple cape to prevent power-interrupt corruption?
Actually, my initial desire for creating the cape was to have a battery-powered Linux node that could power on, perform some task, and then power itself back off and consume very little power in between. So, the cape will selectively power up the BB on a timeout, an external signal, button press, or DC power restoration. When the BB powers itself down and 3V3 goes away, the cape cuts all power to the BB and then waits for another event. While running, Linux can monitor DC power present and the battery voltage and current through an INA219 on the cape. Everyone kept asking about a charging circuit and UPS functionality. So, I added that. The charger is a nice little part that does dynamic power path management and will augment the DC supply from the battery if necessary and charge the battery when excess DC current is available. The charger will always run when DC is present so you could plug a solar panel into the cape's DC jack and now the node doesn't require a battery change (I *do* plan on using that feature!). So, for the shutdown, the cape itself doesn't do anything since that's a software issue. But since DC power status is reported through a status register over I2C, I used that in a bash script while toying with a podcast car computer. I haven't spent much time on it but it definitely turns itself on and off with the car. I guess the other option would be a kernel module that monitors power good and initiates the shutdown... -Ron On Friday, May 9, 2014 11:17:22 PM UTC-5, ags wrote: Yes, I did find those. From what I read, it seems that both aim at allowing the BBB to run when there is no mains power. In my application, I don't have a need for the BBB to maintain functionality when there is no power (other than battery). I'm simply interested in ensuring a safe shutdown sequence when power is removed. It seems from both posts that this has still not been addressed. These methods are focused on keeping the BBB running on battery power; however, when the battery discharges, I saw no discussion about an orderly shutdown occurring. I'm looking for an immediate, but orderly shutdown, and don't care about sustaining operation (beyond a safe shutdown) when power is removed.

Personally, I went the full capehttp://andicelabs.com/beaglebone-powercape/route because it gave me more flexibililty for power-up events as well as a very low power (~80uA) power off state. -Ron -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
