[beagleboard] Re: Beaglebone Black Ethernet Phy Not Detected on Boot.
I have a BBB that sometimes fails to have a useable network interface at power up. Removing power and reapplying power does resolve the issue. Is there a fix for this issue? Would an upgrrade to Rev C fix this? ... -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] I2C Enumeration - Fix possible?
The enumeration and thus the mapping of I2C devices is confusing. Bus 1 uses /dev/I2c-2 etc. Is there any way to fix this so that the hardware matches the software? Could this be hardcoded in the OS? The current mapping of devices is most disturbing. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: How to enable all i2c
I think that the issue stems from older versions of debian based linux and the newer version that use a device tree. If the echo statement fails then: To enable the I2c-1 on the BeagleBone Black Rev A, B and C: 1. Rev A/B: Open the file /media/BEAGLEBONE/uEnv.txt in an editor (vim/nano) 2. Rec C: Open the file /boot/uboot/uEnv.txt in an editor (vim/nano) 3. Add the key capemgr.enable_partno= 4. Add the ports you want to enable, comma separated (BB-I2C0, BB-I2C1, etc) 5.

Re: [beagleboard] cec-client
Since the cec library and utils packages do not work, maybe those packages should be removed from the list of installable packages. There is no way that I have the time to devote to writing a driver or do any porting of software so someone else will have to it. I have moved to a different platform to do what I need done. If anyone is interested, what I wanted was a way to automatically turn on and off a Rotel receiver based on the status of my Samsung TV. The Rotel only has a RS232 interface so I needed a way to poll the status of the TV and then send the appropriate commands to the receiver via the RS232 port. Without a way to get the status of the TV set, that makes the BBB unusable in this case.

Re: [beagleboard] cec-client
I thought that each flavor of Debian (BBB vs Rpi vs ) was built for a specific platform. Live and learn. For my project, I went with a Rpi as the platform despite the buggy UART on board the Rpi. I fixed that issue with a USB - RS232 adapter. I started to go with a BBB because the UARTs on board the BBB appear to be better than the Rpi. Anyway my project is done and my wife is happy as she does not need yet another remote to watch TV.

Actually, the packaged cec library should work fine with one of the USB cec interface dongles, just not with the on-board HDMI for the 'Bone. There's no need to yank a package just because not everyone has the matching hardware.

You can test this by running top or atop in a terminal while you run your app. You will see that available memory will be almost zero and that is why it is sssooo ssslloooww.

[beagleboard] Ubuntu 14 - poor performance
I just installed Ubuntu 14.04 (eMMC flashed) and something seems wrong. I have a software package that I compile. When I compile it under Debian, it takes about 45 minutes to complete. Now with Ubuntu 14 it has takes 76-78 minutes. Is there something that I should look at or do? I did add a swap file but that did not help. Has anyone else seen a performance hit with Ubuntu 14.04?

Removing root would certainly make it secure. usermod -d / root userdel -r root will make it absolutely secure. Not terribly useful but very secure.

[beagleboard] transparent rs-232 connection
I need to create a transparent rs-232 connection from my pc to a remote device. I thought that the BBB would be a good solution. I need to connect the serial port to a BBB which then connects to a remore BBB over wifi and then out the BBB serial port. I need to do this without logging into either BBB. Here is a simple diagram PC - rs232 - BBB - WIFI - BBB - rs232 - remote device Any ideas on how I can accomplish this?

[beagleboard] uboot messages to ttyO0
I am using ttyO0 as a serial console for another linux machine. When the BBB boots, it sends out messages out ttyO0 which is connected to another machines console. Since a getty is running and the messages get echo'd back, uboot reacts to those messages which stops the boot process..

The way my BBB works is like this: To power up the BBB from OFF when powered from the 5 v jack, I have to press the power button. To power up using the mini-usb connector, all I have to do is turn on the USB power. My question is this. Is there a way to have the BBB automatically power up when power is applied to the +5 jack? . -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Not enough space when using Debian on eMMC
There are a few ways to alleviate the congestion. 1 - remove unwanted packages The X windows stuff takes up a lot of space for example. 2 - move various dirs to a USB drive or SD card. /opt and /var are two good candidates. /usr could be done but that requires some experimentation. If certain libraries are not available at boot time, your could have problems. 3 - create a new filesystem on a SD card and use that for your personal stuff. What I did was to create a new filesystem on a SD card and mounted it as /home. Now I have gobs of space for my stuff. In retrospect, I should have done #2 and #3.

[beagleboard] Dell U2410 hdmi woes (wheezy)
I have a strange one. I am using a Dell U2410 monitor. It just so happens that I have the same monitor described at http://elinux.org/Beagleboard:BeagleBoneBlack_HDMI I loaded the image https://rcn-ee.net/deb/microsd/wheezy/bbxm-debian-7.4-2014-03-27-2gb.img.xz on my BBB When the HDMI output of the BBB is connected to the HDMI input on the monitor all goes well until the X desktop is started. As soon as X is started the monitor goes into power-save mode. Press cntl-alt F1 to get to a non-gui login and the display turns on. Switch back to F7 and the monitor goes into power-save. If I use a HDMI to DVI adapter and use the DVI input on the U2410, the X desktop display is OK. I can even use xrandr to change resolution to 1280x1024 (dvi input) which works fine. I have deduced that when the BBB gets the EDID info from the monitor, it changes to a mode that the Dell U2410 does not like but only with the X desktop. Anyone have any ideas?

Re: [beagleboard] Dell U2410 hdmi woes (wheezy)
The odd part is that it is not going into power savenot really. The Dell monitor will go into power save mode if the video being supplied is out of range. I tried shutting off power save mode first and that did nothing. I have a .xsessionrc file and it already contains what you suggested. I tried swapping cables while it was up and running. When I did that, the monitor briefly displayed what looked like a double image (side to side) and then went into powersave mode. I was wrong about the image URL I used. Here is the URL http://debian.beagleboard.org/images/BBB-eMMC-flasher-debian-7.4-2014-03-27-2gb.img.xz So what I did was add xhost + to the .xsessionrc file Then I logged in and did the following: # export DISPLAY=:0 # xrandr Screen 0: minimum 320 x 200, current 640 x 480, maximum 2048 x 2048 HDMI-0 connected 640x480+0+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1080 24.0 1280x720 50.0 60.0 720x57650.0 720x48059.9 640x48059.9* In the middle of this I tried a few things and found a work around. I added xrandr --output HDMI-0 --auto to .xsessionrc Now I have a reasonable X desktop. We can mark this solved..

[beagleboard] First one, then two, then three....
I bought a BBB about 3 weeks ago. Was impressed enough that I bought two more. I have a few Rpis is use around the house as well so I have a little experience with SBCs Anyway. all three BBB has been flawless. No problems at all. I did discover one thing. Of all the Linux distros out there, I like Ubuntu the best. I found that Ubuntu does not suffer as badly from creeping featurism or from a lack of essential packages. I tried Angstrom first. It got flushed. Then I tried Arch and Debian. Didn't like Arch at all. Debian was tolerable. Lastly I tried Ubuntu. Ubuntu seems to be the easiest to get configured and running. I was porting code in under an hour. I don't use a GUI so Ubuntu might not be for everyone. The really nice part about the BBB is the fact that it boots without a SD card. That leaves the SD card slot available for extra file storage. SInce I do some software development as well as create various appliance-like things, the added hot-plugable storage is wonderful. The only thing I wish for is the ability to change I2C bus speeds on the fly. All in all, I am very happy with the BBB. Well done!

[beagleboard] Re: Problem with UART on the BBB
This issue is very reminiscent of a serial port issue that occurred in the early days of SYSV rel 3 on Intel. What would happen was if the baud rate was high enough, the interrupts would occur so frequently that the kernel would be preempted which would cause the OS to hang. The fix at the time was to throttle the data within the device driver. That worked well enough. When processors got faster and buffered UARTs were used, interrupts were no longer a problem but that code remained...until the day when we were testing POSIX compliance on SVR4 on a SMP 486 machine. Proper throughput could not be achieved. The fix was simple once the developers knew where to look. richard On Saturday, September 21, 2013 3:24:39 AM UTC-5, Andreas wrote: No that is not the same project! :) It's a new fpga board now. http://flighttronics.se/wp-content/uploads/2013/04/shx1fpga_top-1024x557.jpg But I'm just migrating from the BBW to the BBB.
