Re: [beagleboard] Removing packages, how do I figure out the the package names?
Well as with anything, Debian does require some understanding of what you're doing. For some I suppose it could have a steep learning curve. IMHO, Debian is best run with no X. As such a strong understanding of commands available, and the command line interface is a must. You can get a Debian install for the BBB in as little as ~64M in size. This is pretty much a bare install so would not do much. However depending on your build strategy, and knowledge of exactly what you need. I'm sure you could build your own image using Xfce, Xenomi, etc in under 1GB size. Possibly far smaller( no hand on here ). Learning how all this works however can be a huge time investment. Perhaps one you're unwilling, or even unable to accept at this time. On Tue, Aug 5, 2014 at 10:25 PM, Wally Bkg wb666gre...@gmail.com wrote: Thanks for the info, gives me a place to start. I tried the LinuxCNC/Machine Kit Debian based image (easiest way to get a working Xenomi real-time system to play with), but it was tight on a 4GB SD card and the GUI performance was flat out terrible. I apt-get installed synaptic after I'd ran the script to expand the image to fill my 8GB SD and figured I'd be in great shape, but I couldn't figure out how to make the menu item for it work. I could run synaptic with /usr/sbin/synaptic but my initial impressions were pretty poor. I may give the straight Debian image a try eventually, but so far I'm impressed enough with what Angstrom has to offer in a 1.5GB load that I'm willing to put some effort into continuing with it. The Angstrom GUI seems at least as responsive and much more stable than anything I had running on the much more powerful PandaboardES which ended up being my greatest Linux disappointment. The real strength of Debian/Ubuntu is odds are you're not the first to encounter the issue and the user forums almost always hold the answers.

[beagleboard] Enable SPI interface with LCD 7 CAPE
Hi everyone, i have been trying since weeks to make work togheter LCD 7 cape and SPI interface but trying to enable SPI1 or SPI0 results in pin conflicts: i think there are some pins requested by SPI interface that are in exclusive use by LCD drivers. I wonder if i can write an overlay to assign different pins to SPI interface or alternatively if it is possible to find C code to handle directly SPI interface from user space. (i am using Debian wheezy as linux distribution) Every suggestions would be really appreciated, i don't know where to find other information and it seems strange that on the web i couldn't find a solution for a very common problem like this. Thank you very much, Mirko -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test
I purchased a proto cape from sparkfun with an eeprom. Apparently I can write a dts file and compile it so that I have better control of the headers at boot time. I'm trying to control some dc motors and was only able to find 4 gpios and 4 more pwms that are low and stay low when the beaglebone boots. I can use those for now, but I imagine that in the future this will probably change and I'd like to know how to deal with it. I'd also like to be able to choose my pin layout so that it's a little more intuitive for my students. So my questions are: 1. Can I access and program the eeprom on the proto cape from the beaglebone black? If so, how? 2. How do I make the dts file? 3. How do I compile it? 4. Where do I put it? 5. How do I make debian use it when it boots? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Thank you this is great news. The reason why I didn't go with kernel version
over 3.8.x is because the u-boot that I tried didn't include a default load
device tree.
So now, I'm trying to use the eMMC Flasher from this link :

I have a few problems with the MLO and the u-boot since I have no EEPROM.
I used the old MLO which agrees that I'm using a BBB by default. But I'm
still blocked on the u-boot part.
I tried using the uEnv.txt file with the following args but it is not
working:
board_name=A335BNLT
fdtfile=am335x-boneblack.dtb
uenvcmd=run loadimage; run loadfdt; run mmcargs; bootz ${loadaddr} -

My main problems are the following:
** Unable to read file /zImage **
** Unable to read file /boot/dtbs/3.8.13-bone59/am335x-boneblack.dtb **

Re: [beagleboard] Error: invalid swi expression Error: value of 0000000000070000 too large for field of 2 bytes at 000
Thanks for the suggestion, Jerome.
As you suggested, I tried passing the value with $, like below
asm(SWI $458752);
But it did not worked.
Then, In some link in internet , I found out that, my arm cross
compiler(arm-linux-gnueabi-gcc) automatically generates thumb
instructions, and somehow this instruction is not supported with that.
So, I just added -marm in the compiler option, to not to generate thumb
instructions and it worked out.
Now, I am not getting this error, and it compiled perfectly.
Thanks for your help. Regards,

Hi Robert,
Thank you, it's a good news.
The main reason I stayed on the 3.8 kernel version is because I wanted to
use the same kernel that was in the BBB. But it appears that the work you
made on the capemgr will be of help for my custom board.
However, now I have another problem.
I'm trying unsuccessfuly to use this flasher:
http://elinux.org/BeagleBoardUbuntu#eMMC:_BeagleBone_Black
The problem is that the u-boot and the MLO doesn't have a default dtb. And
since I don't have a EEPROM, the boot is stuck.
I tried to use the MLO from the BBB, which seems to be OK. And now I'm
trying to use the uEnv.txt file to pass the BBB arguments to the u-boot but
I still can't boot properly.
The error that I can't resolve is essentially:
Bad Linux ARM zImage magic!
I know that the EEPROM should contain this:
struct am335x_baseboard_id {
unsigned int magic;
char name[HDR_NAME_LEN];
char version[4];
char serial[12];
char config[32];
char mac_addr[HDR_NO_OF_MAC_ADDR][HDR_ETH_ALEN];
};
Does this problem have something to do with the magic argument ?
Is it eady to resolv ?

Yes, my custom board has the same RAM and µP. Only the eMMC is a 32GB one
but I think that this will not be a problem.
I'll try to apply the patch to the u-boot.

Re: [beagleboard] debian: 2014-08-05
Very cool Robert, I suspected as much which is why I asked( ipaddr - client_ip ), I'll have to give that a thorough look see at a latter time, but just gave it a glance. I think I get the gist. One thing I have been wondering about for a while, is if it is possible to TFTP/NFS boot over g_ether. I remember reading some uEnv.txt files from apparently older beagle hardware and I think it is possible, but have not attempted passed trying once or twice. It seems we could usb start, and then I'd have to read some of that older stuff to remember the rest of it, but . . . yeah unless it's been patched out. Which wouldn't make sense to me, but I suppose it is possible. So I guess what I am asking here is if it is possible. IF so, I have no problem experimenting on my own to get it working.

[beagleboard] Cannot open device file (in /dev) after reboot
I have a custom 3.8.13 build running on the BBB with my own device tree overlay, as well as my own kernel module. On a fresh build, (the first time the BBB boots up) the kernel module loads automatically on boot, and the driver and device work perfectly. However, after rebooting the system and manually modprob-ing the driver, my userspace program tries to open the device in the /dev folder and returns (using perror() ) No such device or address. The file exists in the /dev folder and is listed correctly in both /proc/devices and /sys/class. As soon as i re-create a new image and boot it up, it works fine again, until a reboot occurs. I'm using printk debug statements within the kernel module that show that the module is actually inserting and running correctly. Also, i have two other kernel modules using the exact same initialization routines, process, etc, and neither have this problem. Is this an error with my device tree overlay, or is this incorrect initialization/cleanup within my kernel module? Thanks for the help.

[beagleboard] Re: rs-232 communications over ttyO2 (not console)
In my case it was /etc/init/serial.conf and NOT the ttyO2.conf file...

Thankyou very much its working now.
Here are my steps.
Mount the sd card into you development machine (I use Ubuntu).
My target OS for the beagleboard is also ubuntu.
delete the following out of uEnv.txt from the boot partition of the sd
card.
- console=ttyO2,115200n8
- optargs=console=tty0
- console=${console} ${optargs}
Modify the /etc/init/ttyO2.conf file in rootfs.
open the file manager as root, for me this is:
# sudo nautilus
as directed by ahmet delete the first line in ttyO2.conf which is:
start on stopped rc RUNLEVEL=[2345]
Now unmount the boot and rootfs partitions and insert into you BB_xm
(target device) and power on.
Once you are booted investigate the baud rate of the serial port.
# stty -F /dev/ttyO2
I get:
speed 9600 baud; line = 0;
-brkint -imaxbel
Now test the port, set up a serial port on an external machine using
whatever works for you, hyperterminal, minicom or gtkterm. Set it to:
9600, 8-n-1, no flow control.
Now send some text to the serial port from the bb_xm and you should
receive it on the external machine.
# echo test /dev/ttyO2
Once received set the bb_xm ttyO2 port to receive on the commandline:
# cat /dev/ttyO2
Now send data from the external machine and it should print on the
BB_XM commandline.
That should be it, for me ttyO2 is setup and tested for use.

Hello
I have been trolling the web trying to workout how to use the built-in
ttyO2 to perform rs-232 communications. I wish to use the built-in
rs-232 transceiver.
I have found how to disable ttyO2 as a console by deleting the console
arguement out of uEnv.txt and removed /etc/init/ttyO2.conf. So now the
built-in rs-232 port doesn't present itself as a console.
The following is what I deleted:
Sudo rm /etc/init/ttyO2.conf
delete the following out of uEnv.txt from the boot partition of the sd
card.
- console=ttyO2,115200n8
- optargs=console=tty0
- console=${console} ${optargs}
However I can't seem to go any further. I have been trying to set the
port as 9600 8-n-1 with no flow control from the command line on my
dvi monitor. However I can't seem to get stty or setserial to perform
any commands on ttyO2.
I was wonder if anyone had a bash script or knew commands that have
worked on the beagleboard xm to setup ttyO2 into a known configuration
and check the ports configuration.
My understanding is that I once I can configure the port I should be
able to simply type on the commandline to send data out the port:
Echo test /dev/ttyO2
Any help would be appreciated.
Thankyou
