Re: [beagleboard] Re: Cross compiling linux for BBB
I do too .Disapointed by the recent events from Angstrom side I think it's
a good way and alternative to buildroot.
PS : in the build_kernel.sh you use a
make -j 8
assuming the user will have 4 cpu which is not allways the case. Maybe
something like
cat /proc/cpuinfo | awk '/^processor/{print $3}' | tail -1
would help to retrieve CPU cores to x2 to be more generic.
Anyway very interesting notes.

how to build a bin file for flashing ?
I have looked at and can't find something like that

According to thread linked below the BBB will be going towards debian,
is there a tutorial on how to cross compile debian ?

Re: [beagleboard] current solution for JTAG debugging of beagleboard xm?
My own time to me is free . . . then while CCS may work, and well for you.. I have plenty of hand on with the software since CCS v4.x up until v5.3.x. But without me getting into too much detail. Let us just say the software is not for me. I already have my own toolchain / IDE setup, and I do not have any problems with using GDB from the command line on Windows or Linux. Also I already own a J-Link emulator . . . but have limited hands on with it.

Hi Robert, It really depends on what you are trying to achieve. If you want to understand the workings of JTAG, then flyswatter is a good solution. If like the rest of us you just want to debug u-boot or kernel code, then XDS100V2 or XDS200 together with CCSV5 is a good solution. One thing to note, although you can debug Linux Kernel code, CCSV5 isn¹t kernel aware so there are limitations in what you can do. Strangely, CCSV4 was Linux Kernel aware, but TI decided that CCSV5 stay as close to the standard Eclipse IDE as possible and avoid extensive customization required for making it Linux Kernel aware. Also, with the addition of DWARF4, it is now possible to see most of the local variables. If you want kernel aware debugging, then I suggest you use ARM DS-5 or Lauterbach, but these are expensive solutions. I have also used PEEDI which is a very good solutions and is Linux Kernel aware and uses standard Eclipse IDE. Regards, John rday -- Robert P. J.

I'm working on aBeagleboardplatform used in a set of manufacturing test fixtures, complete withGTKgraphic UI, and a bank of I2C port expanders, and ADCs. I found the neatest, fastest way to develop the GUI was to use Glade 3 on my host machine. This produces an XML file that can be used on the target. http://glade.gnome.org/ The bindings are all handled by a Python script, using the PYGTK module. This is available via the package manager within Angstrom. All of this allows you to make rapid tweaks to the GUI's appearance on your host machine, and then you copy the glade (XML) file over to the target. This makes it very easy to re-skin your application, without touching the Python back-end. Also, because Python is a scripting language you can obviously make changes on the fly, without recompiling anything. If you need to do something low-level, then you can write your own C modules that plug into Python.

[beagleboard] Re: PWM input in beaglebone
I'm guessing that you figured this out already or don't care any more. But in case you were wondering, you can use the GPIO pins, google around for this and there's the interrupt method. Maybe the easiest if you don't mind 10bit resolution would be to use the PWM with an optocoupler, like the LED dimming example. Then you could go right to the analog in pin. I guess it really depends on how fast you need to do it. 10 bit is 1024...so that would give you about... 800-20=780; 780/1024 = 0.76kHz per step.

[beagleboard] Re: emacs on Ångström - no keys
Thanks. I would have installed Debian on my machine by now, but the 16GB Toshiba uSD I bought a couple of weeks ago has failed already. After the first couple of days, I had to reformat it repeatedly, both on the BBB and on each of two Windows (XP 7) machines. Win32DiskImager didn't work at all on the Windows 7 machine: it repeatedly hung as soon as I got to the writing phase in a way that required rebooting the Windows machine. I loaded and ran a disk imaging program from an outfit named RoadKil.net -- that's a sign of real desperation!. It got into the writing phase, but its progress stopped at 0.06%. At least it was possible to end that program without rebooting the machine. I'll try to load Debian again as soon as I get another uSD, and not a Toshiba this time. - R P.S.

[beagleboard] Java program with RxTx cannot find /dev/ttyUSB connected device
Hi all, I've been working on a project with XBee communication boards which utilize USB connection to transmitt and receive messages. The program is written in Java and uses RxTx library 2.2pre2. I've written tested the program on PC running Ubuntu 12.04LTS and everything works great(i can send and receive messages both directions), when i deployed the program to BBxM this is when the troubles start. My BBxM is running Ubuntu 12.10, with java 1.7. I am a pretty new to Java and total n00b in BB so i'm having trouble running my program. My XBee board is connected to USB port as /dev/ttyUSB0 just like it was on my PC. So the same configuration should work for both platforms, but when the RxTx instance is initialised i get error that it cannot find /dev/ttyUSB0. First thing that crossed my mind was rights but rights are already 777 at least for the testing purpose. I've tried few versions of RxTx and every one has the same problem. I haven't done any additional setup of the ports so i'm wondering is there some setup i've missed to make the program behave the way it does now. Any help is greatly appreceated. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] To CANBUS or not to CANBUS
CAN bus is mostly for automotive applications. All contemporary cars have this bus and all inner units in a car interact through this bus For industrial applications rs485 is the most widely used bus, but it may depend on your budget. Sometimes a radio connection is better than simple wiring. 1-wire is an option too, but this bus has significant limitation on the wires length You can also find out details about ZigBee devices. 06 янв. 2014 г. 1:08 пользователь Michael Cummins michael.e.cumm...@gmail.com написал: Relatively new to small platforms and Linux in general. Have a new BeagleBone Black and am thinking about monitoring/logging sensors for future projects like monitoring solar heating, power consumption, state of devices in home, etc. I read that CANBUS is a preferred method for multiple sensors on a long wire. Would you agree? What does the CANBUS Cape offer beyond what the BBB can already do? Should I skip the wire and learn to work with wireless sensors first? I imagine the cost is higher, but would that be a more robust and more easily managed network? Someone on the forums implied that the future of BBB and Angstrom is in question. Should I do my learning on Ubuntu instead, as I'm just getting started?

something like
cat /proc/cpuinfo | awk '/^processor/{print $3}' | tail -1
would help to retrieve CPU cores to x2 to be more generic.

[beagleboard] Changing Kernel back to 3.2 for Angstrom - Steps
Hello,
I am trying to find out how to build the Rowboat 3.2 Kernel and apply it
over the latest Angstrom build in the hope to get to a working OS which
works for LCD Capes, such as the LCD4, LCD7, 4DCAPE-43T and 4DCAPE-70T
I have been told that going back to a stable 3.2 kernel may result in a
more favourable outcome, as current the touch issues present on the 3.8
Kernel almost render the capes useless.
I have been emailing Robert Nelson. Thanks very much for your help.
Just need some help to ensure I am doing it correctly, and also how I go
about getting the built kernel onto the BBB as I have never done that.
So to start with, I am going to try and use the 2014-01-03 Distribution:
http://downloads.angstrom-distribution.org/demo/beaglebone/testing/
I have just installed VM Player on my PC and have Ubuntu 13.10 installed.
I am following the instructions from
here: http://elinux.org/Building_BBB_Kernel
and here:
http://wiki.beyondlogic.org/index.php/BeagleBoneBlack_Building_Kernel
Robert said to do the following bits instead:
*git clone git://gitorious.org/rowboat/kernel.gitcd kernel/git checkout
rowboat-am335x-kernel-3.2 -b tmpmake ARCH=arm CROSS_COMPILE=${CC}
am335x_evm_android_defconfigmake ARCH=arm CROSS_COMPILE=${CC} zImage
modules*
I am still working on that, but after this is complete, I am not sure what
the easiest method is to get it on the BBB or if there is anything else I
need to do?
I wanted to start this so others could also follow if they wanted to, as I
am sure I wont be the only one who has little experience with this
Thanks
Terry

[beagleboard] Re: Boot failure external abort on non-linefetch in cpsw_probe with any image after Wi-Fi install
@RobertCNelson: Your kernel is out of date, please upgrade to v3.8.13-bone35 first... That kernel version is from attempts to boot Ubuntu. Maybe I could find a newer Ubuntu image, but I have the same kernel panic problem trying to boot Angstrom. It only says: ## Booting kernel from Legacy Image at 80007fc0 ... Image Name: Angstrom/3.8.13/beaglebone Image Type: ARM Linux Kernel Image (uncompressed) Data Size:4270776 Bytes = 4.1 MiB How do I tell if that is out of date? It is specifically the image the RMA people told me to use - BBB-eMMC-flasher-2013.09.04.img.xz There seem to be a maddening variety of images available, but I haven't found any newer production versions. @Vaibhav: PHY reset timed out I guess ^^^ that's your problem. I can't see why the WiFi will interfere with the CPSW. I've seen lots of boot logs show those lines and still boot successfully. Your links and others I've found are about the ethernet dying after an hour or more, or failing to start maybe 1/50 times while the rest of the board boots successfully. My Ubuntu boots do show a later version of phy not found - just before the fatal error: - [2.459389] davinci_mdio 4a101000.mdio: davinci mdio revision 1.6 [2.465825] davinci_mdio 4a101000.mdio: no live phy, scanning all [2.472570] davinci_mdio: probe of 4a101000.mdio failed with error -5 [2.479609] Detected MACID = 90:59:af:4d:71:eb [2.484177] Unhandled fault: external abort on non-linefetch (0x1008) at 0xe089e000 [2.492394] Internal error: : 1008 [#1] SMP ARM - But right after saying the probe failed, it displays the proper MAC address for the interface it couldn't find! Something is obviously screwed up, but my kernel booted fine before I tried to install Wi-Fi, and it is the one Beagleboard RMA says I should use. Wish I had boot logs from back then, but my first console port adapter arrived with a bad cable. I'm not seeing anyone else (except for the one link I posted) say cpsw_probe totally prevents booting. And in that one instance, the kernel that failed in one board worked in the other five... -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

@Vaibhav, Just found this: http://web.archiveorange.com/archive/v/vEQ2y6LmBVoCWJwTbcnr about a problem with clocks not being enabled before mdio: probe - which seems directly applicable to my Ubuntu fail! Make the driver control the device clocks. Appearantly, the Davinci platform probes this driver with the clock all powered up, but on OMAP, this isn't the case.Make the driver control the device clocks. Appearantly, the Davinci platform probes this driver with the clock all powered up, but on OMAP, this isn't the case.
