Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test
This is a quirk of Debian. Systemd represents a pretty fundamental shift to Linux distributions. Conservative distributions like Debian have taken a wait and see approach before adopting it. As a result the version of systemd in Debian stable, Sid, is pretty old. One option would be look at using the current development version of Debian, Jessie, which will become the next stable release later this year or early next year. As with everything it is and engineering trade off; old and stable vs. new and awesome :) David On Thu, May 29, 2014 at 1:00 AM, michael.du...@gmail.com wrote: On Wednesday, May 28, 2014 2:37:13 PM UTC-7, RobertCNelson wrote: It's there just an older version of systemd where it was prefixed. systemd- Follow-on question: any risk in moving to the latest version of systemd?

Re: [beagleboard] Re: MediaTek (Logic Supply) Wi-Fi adapter for BBB and Debian
Alternatively, you can use the included wicd utility to manage your network connections. To make it work with the UWN200, you will need to edit the config file to point to the right interface: /etc/wicd/manager-settings.conf https://lh5.googleusercontent.com/-UD1gFu6D6ZI/U4cpXejMQzI/Aaw/nAH1STy1aOQ/s1600/Capture.JPG Then you can use wicd-curses to connect to your access point. I set mine to autoconnect, and DHCP takes no time at all. And yes, a 5V AC adapter connected to the wall is always recommended when using any peripherals.

Re: [beagleboard] Using Beagle board to get RSSI of a device
Hi Richard, Thanks for your reply. I am not quite sure how to find out the driver for TL-WN722n on our ubuntu systems. We didn't have to actually install any driver on the beagle board (running Ubuntu 12.04 LTS omap) or the stand alone PC (Ubuntu 12.04) for our project. Can you assist in helping out to find the driver version for TL-WN722n wireless adapter to see if that is the reason. Thanks.

Re: [beagleboard] Custom Beaglbone Black from Circuitco
Gerald, exactly! I have so many RFQ for 100 or even 1000pcs and people just can't understand that so small volume is not even a volume for an assembly line and consequently unit prices are higher than BBB price. These people just purchase BBB for commercial projects although they should not. Distributors simply accept their orders If you want low cost than order at least 10k. For example I don't even know any Chinese factory which can accept orders less than 10k and even for 10k they will charge at least 100% of components cost. It's business, nothing personal. No one will donate your dreams 2014-05-29 17:10 GMT+04:00 Gerald Coley ger...@beagleboard.org: Not to mention. If you build a custom BBB, and make 100 pieces, the cost will be around $300 to $500 a board after you pay the NRE and high cost of buying only 00 boards. .The reson this board is low a sit is is that we add a three zeros to the 100 number.

[beagleboard] Best way to connect to Arduino via serial?
Hi! I currently have an Arduino Mega 2560, and have pre-ordered one of the new BBB rev C's. The Arduino collects data from environmental sensors placed around our house, and among other functions, is set up to dump the data from the sensors over serial. I'm planning to have the BBB connected to the Mega over serial to collect the data, store it in a database, and notify me via push messages should something go out of the ordinary. However, I'm concerned about blowing up the BBB, since there are a lot of caveats about making sure that things are sequenced properly and that no power is applied to the BBB inputs before it's ready. I know that the Arduino outputs 5v signals, and the BBB can only handle 3v3, so to address that, I've built a logic converter board based off of some ZVNL120A mosfets, following Phillips' App Note AN97055. My big question is - what's the best way to prevent damage to the BBB? Should I add some extra mosfets inline with the rx and tx lines, and control the operation of the mosfets from the BBB (so that when the BBB is off, the serial connection to the Arduino is disconnected)? Or is there some other way that I should handle this?

Re: [beagleboard] Reference OS.
Jjust pick a distro ( all are Linux, e.g. OS ), and stick with it. I will however let you know, that the best supported distro right now is Debian. Robert does a bang up job, and is very active on these groups. Not to mention that Debian is well documented on the internet, where 90% + of any ones answers can be answered by using google. This post of yours seems circular in relation to the last post or two you've made on these groups. Dancing around the same subjects. SO my advice to you is just pick *SOMETHING* (I would recommend Debian ), start learning one thing at a time, and do not stress out on the whole big picture ( all at once ) I would also recommend that you setup a virtual machine with Debian on it to toy around with until you feel comfortable with various aspects as you learn them. The only way you're going to learn is by doing.

Based on the various threads on this and other lists, it does not seem that I am alone. I agree with Gerald, but I'll try to address some of your concerns from my perspective as well. The variety and changing nature of software does create some support challenges. Part of our strategy has been to make BeagleBoard.org hardware a first-class citizen of various community software projects. In that light, you can get lots of support for those projects in their normal support channels and come here to figure out the BeagleBoard/BeagleBone-specific details. Would be possible to achieve consensus around a single OS as the ref Operating System for the BBB? While I support individuals freely choosing which distribution best meets their needs, the overall project would be best served by focusing on the foundation.

All operating systems are welcome here. 1. Would it be possible/reasonable to suggest that other BeagleBone users migrate from Angstrom to Debian? Possible, yes. Reasonable, depends. If Angstrom does what you need, then why not stay with it? 2. Would it be possible/reasonable to articulate that the BeagleBone community will focus their development and support efforts on Debian? The community is diverse and supports many software systems. There's some focus on Debian, but we should be working with Fedora, Arch, FreeBSD and lots of others too. There is a bit of a BeagleBone out-of-box-experience, but it is meant as just a gateway on to deeper learning and development. 3. Would it be possible/reasonable to suggest that support on this mailing list will focus on Debian? No. We try to avoid forking lists when when can. Impressions of that have been mixed, but I think if there is enough interest in creating a Debian support list focused on BeagleBone Black, then someone will make it and attract community members there. Personally, I like having this one list with all the topics and relying on people to create reasonable subject lines. Folks can tag messages as well to put them in various categories.

I'm planning to have the BBB connected to the Mega over serial to collect the data, store it in a database, and notify me via push messages should something go out of the ordinary. However, I'm concerned about blowing up the BBB, since there are a lot of caveats about making sure that things are sequenced properly and that no power is applied to the BBB inputs before it's ready. I know that the Arduino outputs 5v signals, and the BBB can only handle 3v3, so to address that, I've built a logic converter board based off of some ZVNL120A mosfets, following Phillips' App Note AN97055. My big question is - what's the best way to prevent damage to the BBB? Should I add some extra mosfets inline with the rx and tx lines, and control the operation of the mosfets from the BBB (so that when the BBB is off, the serial connection to the Arduino is disconnected)? Or is there some other way that I should handle this?

Re: [beagleboard] BBB LCD3 Cape and inactivity
I'd agree except I am seeing it with two different LCD modules BB-View and Cape LCD3 LCD4 - different designs, different circuit, different manufacturer. I'll have to noodle on it. ~C On May 29, 2014, at 1:42 PM, John Syn john3...@gmail.com wrote: From: Colin Bester bester.co...@gmail.com Reply-To: beagleboard@googlegroups.com Date: Thursday, May 29, 2014 at 6:45 AM To: beagleboard@googlegroups.com Subject: Re: [beagleboard] BBB LCD3 Cape and inactivity I just managed to get around to looking a little deeper into this and connected an oscilloscope to EHRPWM1A (which I figure is pin P9_14) and confirm that when writing a zero to brightness (using echo 0 /sys/class/backlight/backlight.11/brightness) that the pin is low.

[beagleboard] 3 proposed patches for next 3.8.13-bone5x update
I've attached three patches for consideration in the Robert Nelson's
3.8.13-bone5x update, all of which are independent of each other (i.e., you
can patch your kernel with any one of them, separate from the others):
0001-am335x-features
Detect AM335x-specific features and CPU version. Doesn't do anything
significant, other than accurately report the CPU and SGX, L2 cache
presence in the bootup dmesg output.
0002-element14-bb-view-lcd-capes
Add Element14's BB-VIEW LCD cape device trees to firmware/capes.
0003-sitara_rb_swap_workaround
Create a workaround to the TI Sitara red/blue swap erratum through device
tree properties, 'bgrx_16bpp' and 'bgrx_24bpp'. The 'bgrx_16bpp' property
swaps red and blue if 16bpp color depth is used and the LCD cape itself
swaps red and blue at higher color depths (i.e., the cape designer fixed
the problem by swapping signals). The 'bgrx_24bpp' property swaps red and
blue at the 24bpp color depth, which addresses TI's erratum.
Also, the tilcdc LCD driver queries the panel's panel-info/bpp device tree
property to find the preferred BPP when initializing the console
framebuffer. This was originally hardcoded into the driver at 16bpp. If the
panel says that it wants 32bpp, the framebuffer initializes to a preferred
32bpp.
I've been testing these changes relative to Robert's linux-dev
3.8.15-bone53 tag. They may apply cleanly against earlier tags, but I can't
guarantee they will.
I'm sure I have canonical kernel source formatting issues; comments,
testing and suggestions are welcome (and advocacy for inclusion in Robert's
linux-dev git repo also helpful.)

But none of the user LEDs turn on. If I power up BBB without boot button pressed, three user LEDs turn on sequentially and remain so without blinking.

[beagleboard] Re: User LED forward to GPIO
Hello faimbs, the USER LEDs are allready connected to GPIO-1, pins 21 to 24. By default these pins are configured as outputs. An easy (and fast) alternative to control USER LEDs is libpruio http://beagleboard.org/project/libpruio/. No need for file access to control the status, just call a function to switch the LED on or off. Find the example sos.c in the package that makes the USER LED-3 blinking in SOS code: - description: http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/ChaExamples.html#SubExaSos - source code: http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/sos_8c_source.html *libpruio can do the pin muxing and control all GPIOs (a*s well as ADC inputs)*. You only need a simple device tree overlay to switch on the PRUSS*. All the other stuff is in your source code (single source). Your program doesn't need root privileges (but the user needs read/write access to */dev/uio5*, see DOC: Preparation http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/ChaPreparation.html for details).

[beagleboard] Re: Best way to connect to Arduino via serial?
the 7-12 volt is the 'raw' power spec. This is converted to 5volt on the board. This is normally the main system power. When you connect 3v3 to the VCC pin the board runs at 3v3. Technically the AVR chip is overclocked at this voltage, but I never have seen an arduino fail doing this. Try it, what can you lose? You make your system a whole lot simpler, using only 3 volt logic. LP On Thursday, May 29, 2014 9:51:36 PM UTC+2, myersco...@gmail.com wrote: Cool. Would something like this work?

Doesn't do anything significant, other than accurately report the CPU and SGX, L2 cache presence in the bootup dmesg output. 0002-element14-bb-view-lcd-capes Add Element14's BB-VIEW LCD cape device trees to firmware/capes. 0003-sitara_rb_swap_workaround Create a workaround to the TI Sitara red/blue swap erratum through device tree properties, 'bgrx_16bpp' and 'bgrx_24bpp'. The 'bgrx_16bpp' property swaps red and blue if 16bpp color depth is used and the LCD cape itself swaps red and blue at higher color depths (i.e., the cape designer fixed the problem by swapping signals). The 'bgrx_24bpp' property swaps red and blue at the 24bpp color depth, which addresses TI's erratum. Also, the tilcdc LCD driver queries the panel's panel-info/bpp device tree property to find the preferred BPP when initializing the console framebuffer. This was originally hardcoded into the driver at 16bpp. If the panel says that it wants 32bpp, the framebuffer initializes to a preferred 32bpp. I've been testing these changes relative to Robert's linux-dev 3.8.15-bone53 tag. They may apply cleanly against earlier tags, but I can't guarantee they will.

Re: [beagleboard] Re: The CryptoCape is now available at SparkFun Electronics
It's a cape that has the following security ICs on the Beagle's i2c2 bus: - Atmel TPM (RSA 2048) - Atmel ATSHA204 (SHA/HMAC256) - Atmel ATECC108 (ECDSA) - Atmel ATAES132 (AES-128-CCM) Plus an EEPROM and a 5pmm RTC. It also contains an ATmega328p, which is loaded with the 3.3V pro mini bootloader. The ATmega is also connected on the i2c2 bus so the Beagle and the 328p can communicate over i2c. Also, you can upload sketches from the Beagle's UART4 to flash the ATmega. The SparkFun product page is here, with a hookup guide: https://www.sparkfun.com/products/12773 The eLinux page is here: http://elinux.org/Cryptotronix:CryptoCape The SparkFun page talks about each IC in more detail.

Re: [beagleboard] The CryptoCape is now available at SparkFun Electronics
Hey Eric, thanks for the question, where did I read that before ;) Thanks for the recommendation, I’ll look into the bus select option. The goal of this board is not to provide cryptographic acceleration, because you are correct, the AM335x does have accelerators already (drivers in 3.13). The purpose rather, is to provide key isolation. So the RSA/ECC/MAC keys stay in the respective chips. For ECDSA for example, the private key never leaves the chip. In the AM335x case, you’d have to provide the key somehow in software. Also, the AM335x doesn’t have any asymmetric crypto options. The TPM provides RSA-2048 and the ECC108: ECDSA with three NIST curves.

Re: [beagleboard] The CryptoCape is now available at SparkFun Electronics
The RTC uses the ds1307 kernel driver and you're correct, it shows up as rtc1. It is loaded when the capemgr instantiates the device tree, since the driver is in the CryptoCape DTS file. So you shouldn't need any init.d/systemd scripting it should just workTM. You'll have to set the clock once and then it should hold pretty well. In testing think I had a bum battery b/c it depleted rather quickly. Once I changed batteries it seems to be holding steady.

Yes, this is nearly identical to the setup I did. Created a dto for the ds1307, loaded it at boot, all good. The device is there, it has very good time. The system still needs to be told to *use* that time. If memory serves Robert updates a time value that gets loaded so if your on a fairly current image your time is somewhat current. I'll be more than happy to RTFM, or experiment if pointed in the right direction. I've not seen any indication that simply adding a battery backed RTC, loading it via capemgr will cause the system (kernel) to use that device for obtaining a somewhat sane time value.

Re: [beagleboard] The CryptoCape is now available at SparkFun Electronics
Are you guys talking about the crypto cape or the RTC cape? The crypto capediscussed in this thread uses a ds3231 not a ds1307. Also why anyone *needs* the rtc cape I don't get. just keep the rtc rail powered on the processor. That I believe is a software issue.

Re: [beagleboard] The CryptoCape is now available at SparkFun Electronics
Eric, You are correct, the CryptoCape has the DS3231. However, it use accessed via software via the ds1037 kernel driver. That driver is compatible with the 3231: http://lxr.free-electrons.com/source/drivers/rtc/rtc-ds1307.c, line 36. I haven't tried any of the other features like the Time of Day alarm so I'm not sure if that's supported with this driver. I put the battery on the CryptoCape so that the RTC will maintain time [1] when the cryptocape is physically removed from the Beagle and [2] when the Beagle is not connected to power.

The Cryptocape RTC is what I was specifically asking about. The ds1307
modules handles several rtc chips.
enum ds_type {
ds_1307,
ds_1337,
ds_1338,
ds_1339,
ds_1340,
ds_1388,
ds_3231,
m41t00,
mcp7941x,
rx_8025,
last_ds_type /* always last */
/* rs5c372 too? different address... */
};
I'd be happy to pursue keeping the rtc rail powered. I have no clue
where this is or would be handled in software. I'm far from being any
kind of good programmer, and know far to little about hardware at this
level. Just a long time sys admin willing to learn it if pointed in the
right direction.
