[beagleboard] Is anything logged on power failure?
I *think* my BBB is getting powered down becauae the 7805 chip I'm using it needs a heatsink and is thus running just a bit too hot and protecting itslef by turning off. Is there any way to tell if this is happening from the BBB logs? I can't see anything obvious in syslog at all. When it has turned off *all* the lights are off and I have to remove the power and restore it to restart the BBB. Does this suggest the 7805 is turning itself off?

Re: [beagleboard] Is anything logged on power failure?
If you cut power, the processor turns off so it is hard for it to keep running and print logs without power. Hook a meter to the DC input and see if it turns off. If it does, the 7805 is shutting down. The best that can do is 500mA without a heat sink,.

[beagleboard] What's in a Beagle Bone other than the circuit diagram?
Hi Beagle users, A little about me before I explain my question. I'm an experienced electrical engineer with a heavy background in micro processor implementation and programming as well as PCB layout for high speed digital design. I'm fluent in C and C# and open to learning other languages. I am, however, totally new to SoC (and embedded Linux OS) concepts outside a basic knowledge of computer system architecture. I am currently at the stage of working out if the Beagle bone black is the correct starting point for me. My interest in the Beagle Bone is for product development with a view to commercialization. This will require a re-design of the board architecture into my own PCB design and I am attracted to the BBB as it is fully open source and the processors are available commercially (unlike the RPI). So, my question is. If I simply cloned and populated a PCB, matching the circuit diagram of the BBB and plugged an SD card in (with OS flashed on), would it work. Or is additional software required to be loaded onto the SoC device? If so, is this bios / boot loader available? Additionally, if I develop a program to run on Rasbian. How easy would it be to port it onto a BBB OS (such as Debian)? Tanks for any assistance you can offer.

Re: [beagleboard] What's in a Beagle Bone other than the circuit diagram?
If you copy it exactly and build it correctly it should work. People do this all the time. I would expect SW to have to be added to support whatever you put on the board to fit your application. There is no SW loaded onto the SOC. All code for the SOC is loaded from an external source, eMMC or SD in this case.

Or is additional software required to be loaded onto the SoC device? If so, is this bios / boot loader available? Everything is available, but there is a minor amount of content that isn't in the schematic/pcb design files. There is an EEPROM that contains board ID information, and if you're using the standard software, your board won't boot properly unless you load appropriate contents into this EEPROM. If you're not familiar with Linux on ARM, the boot sequence is: * SoC ROM contents * MLO (Memory LOader), part of uBoot * uBoot * Linux kernel * Normal linux boot There is source available for everything you need, and you can modify the uBoot loader if you want to leave off the EEPROM. Additionally, if I develop a program to run on Rasbian. How easy would it be to port it onto a BBB OS (such as Debian)? Assuming you're not doing anything really hardware specific, you should be able to directly port code from Raspbian to Debian on the 'Bone or most any other platform.

[beagleboard] BBB Analog Digital Convertion error on Ubuntu

I use 3.3V and Analog ground with PTC (positively change the resistor heat with respect) but sometimes I got max measurement such 1760 mV. So is there something wrong with Ubuntu or what I did. What I did for init.d folder I added as a bash contains: if [ ! -d /sys/devices/ocp.2/helper.14 ]; then echo cape-bone-iio /sys/devices/bone_capemgr.9/slots; fi so it works... But I got miss conversion SOMETIMES (1 miss per 10 samples). I used for AIN1 (P9-40) connected a PTC with parallel 480 ohm resistor and P9-03 3.3V and P9_34 AGND. I did not used VADC P9-32 as reference.

[beagleboard] Why beaglebone black restarts after a shutdown ??
Hi, I have noticed that the beaglebone black starts up after a shutdown. I have a C++ program running in the bbb, the bbb is backed by an external +5V battery pack. When the C++ program issues the following command to start the shutdown procedure of the bbb. system(shutdown -h now); exit(0); This does shutdown the bbb completely sometimes, most times the bbb starts up again, the power led turns off but then after a second or two lights up again and then bbb starts up all over again (the output voltage from the power bank does not switch OFF, it remains ON for some time). In my previous bbb systems I have not faced this problem. It is my belief that the output voltage from the power bank has a sudden dip, this causes the bbb to detect a new power cycle. I am not sure though if I am correct... Could anyone enlighten me on this problem ???

Re: [beagleboard] Why beaglebone black restarts after a shutdown ??
Yes it does sound vague. I would hook a scope to the power and see what it does in the reset scenario. What is your current capacity of your power source? If the power pin is held down too long, it will result in a power cycle and not a shutdown.

[beagleboard] BBB with Angstrom using PWM Input from Ultraonic Sensor
Ok, so I have a project that started out using an Arduino Mega. This project uses an Ultrasonic Sensor to give me distance measurement, and the sensor returns data over PWM. So, I need this project to be web connected and have some data logging, and instead of having an Arduino cobbled with something else and writing custom code and such, I went with the BBB. It's running the stock Angstrom (with opkg upgrade completed) and I am trying to figure out how to get this sensor to interface with the BBB. preferably I would like to use the sensor as one would any GPIO by querying a file in the /sys tree, but the couple tutorials I have found have not worked and were for Ubuntu. While I prefer Ubuntu, I have been told that Angstrom has built-in support for PWM and has all the PRU items and dts overlays in place to do what I want, I just can't figure it out for the life of me. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] BeagleBone Black BBB UART Tx doesn't work without booting with Ethernet plugged in
Hello all. The title just about says it all but here are details. I have a python script which uses a few UARTs and some GPIO. It uses the Adafruit UART/BBIO/etc. libraries. It is run on startup using systemctrl services where I have it set as Type=idle in the service definition in order to force this script to run after all services are set up. This script works fine and my UART works great when I boot with Ethernet. If on the other hand I boot with no Ethernet plugged in as I intend to do, the program runs fine except for odd behavior on the UART. The rx of the UART works fine and my program receives and logs incoming bytes. But the Tx appears to be dead. It will not transmit. Python's PySerial write function returns that it wrote the amount of bytes it should have but nothing comes out the port. This happens 9 out 10 boots. The only perfect fix is to boot with ethernet plugged in. Any ideas? Using a stock BBB with Angstrom Linux. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

It seems to me that if Debian is going to replace Angstrom, then a link to the Debian release images and FAQs should be put there. Eventually, the Angstrom info could be deprecated, or rather archived and its visibility reduced. It seems to me that there are currently too many places to go to get the various linux distributions and kernels, and none of them seem to be officially sanctioned as the standard release. This leads to unnecessary confusion for new users. Some info on beagleboard.org, some info at circuitco.com, some info at elinux.org, some info at armhf.com, etc., not to mention all the other stuff at ti.com. The official wiki at http://www.elinux.org/Beagleboard:BeagleBoneBlack#Software_Resources doesn't even mention this Debian releases (and it should if you want people to test it). The community wiki at http://elinux.org/BeagleBone_Community#Debian does list a Debian release, but it is a different, and incompatible, arm EABI version from this new armhf release. I appreciate all the hard work that people have done to prepare all this information, but it's a little like the wild west when you first start looking around.

Latest Kernel has DHT11 and DHT22 drivers under IIO subsystem. We shall see it working on BBB very soon. regards, Benito.

As you say, to initiate communication with the DHT11/DHT22, you're supposed to pull the signal low for 18 ms, then high, then wait for the signal to be pulled low again. Their code appears to skip the pull-high part. I can only assume that the Pi stops pulling the signal low when it switches to input mode. The only possible problem I can see in your code is that you might not be pulling the signal low for long enough: perhaps the usleep(2000) should be usleep(2)? Also, trying to catch that 40 microsecond signal that begins the DHT22's response is tricky - that's probably why the Pi's code doesn't pull the line high explicitly. Perhaps dropping the digitalWrite(HIGH) from your code would have the same effect? I gave both of these a whirl, and they did not work. I am able to see the signal on my oscilloscope, though I'm new to using the oscilloscope, so I'm not 100% sure. I have my doubts about whether reading data from the DHT22 can work reliably from Linux code, given the tight timing involved. Apparently the Adafruit code is managing to do it on the Pi, but there is a warning at the beginning of their tutorial saying it may not work, and perhaps the library they are using is more optimized than what is available for the Bone. Yes, I read that. I'm starting to have the same doubts as well. Personally, I wimped out and use a separate processor to read the DHT22. I actually use a .Net Micro Framework processor for this (which surprisingly is able to handle the timings) and serial I/O, but something like the ATTiny2313 and I2C would be a better design. I'm starting to think I might need to do the same. I'll give the Pi a try, and I've got an Electric Imp on the way, so I'll probably try it too. That would appear to be an overkill to toss in another processor. Prehaps a different part would be more appropriate? FWIW, I recently got a humidity sensor working on the classic Beagle. This is the SHT-15 part. Everything pretty much was drop in. Hookup. The setup was: SHT-15 - Level Converter, 3.3V source - Beagle Classic. Driver for it was all upstream. It is built on top of the GPIO subsystem. The level converter and 3.3V are option on the beaglelcd board. Write up for it will be posted as time permits. Since IO on the bone is 3.3V, the level converter won't be needed. I've built a meat curing fridge, and I'm trying to build an internet enabled controller. I've built a monitor for it using the TI Launchpad, and I'd like to build something that will post the information to the internet (without hooking up to my laptop and reading from a TTY). I suppose I could try XBee, but everything seems much harder since I'm not using an Arduino. :-( Anyway, thanks for the response. If I can't get the Pi or the Imp to work out, I'll hook the Launchpad up to the Bone via UART. Again, thanks for your time.

It seems to me that if Debian is going to replace Angstrom, then a link to the Debian release images and FAQs should be put there. Eventually, the Angstrom info could be deprecated, or rather archived and its visibility reduced. It seems to me that there are currently too many places to go to get the various linux distributions and kernels, and none of them seem to be officially sanctioned as the standard release. This leads to unnecessary confusion for new users. Some info on beagleboard.org, some info at circuitco.com, some info at elinux.org, some info at armhf.com, etc., not to mention all the other stuff at ti.com. The official wiki at http://www.elinux.org/Beagleboard:BeagleBoneBlack#Software_Resourcesdoesn't even mention this Debian releases (and it should if you want people to test it). The community wiki at http://elinux.org/BeagleBone_Community#Debian does list a Debian release, but it is a different, and incompatible, arm EABI version from this new armhf release.

Hi, I have noticed that the beaglebone black starts up after a shutdown. I have a C++ program running in the bbb, the bbb is backed by an external +5V battery pack. When the C++ program issues the following command to start the shutdown procedure of the bbb. system(shutdown -h now); exit(0); Try ³halt² instead. Regards, John This does shutdown the bbb completely sometimes, most times the bbb starts up again, the power led turns off but then after a second or two lights up again and then bbb starts up all over again (the output voltage from the power bank does not switch OFF, it remains ON for some time). In my previous bbb systems I have not faced this problem. It is my belief that the output voltage from the power bank has a sudden dip, this causes the bbb to detect a new power cycle.

It's a patch file to apply to the spidev.c file. As it's only one line

Make sure you change the IP address and userID for nfsroot to match your host IP and userID. My local network uses an address 10.100.116.xxx. My BBB is 10.100.116.104 and my host is 10.100.116.73. You need to install nfs-kernel-server on your Ubuntu host Add the following line to your /etc/exports file on your host /home/userID/targetNFS 10.100.116.0/255.255.255.0(rw,insecure,async,no_wdelay,no_root_squash,no_sub tree_check) Place your rootfs in /home/userID/targetNFS on your host sudo service nfs-kernel-server restart I think that is all, so NFS should work for you. I hope this helps.
