Re: [beagleboard] BeagleBone 3.1MP Camera and Beaglebone Black Compatability
I've managed to get it to work, but now I'm running into a problem with the device driver. When I try to capture an image with openCV, I receive the following error: VIDIOC_REQBUFS: Cannot allocate memory. Is there somethign in the uenv.txt that needs to be set for the camera to function properly with openCV? I can make it work fine with Cheese and mplayer.

Is this a simple problem software issue, or are there fundimental compability problems between the two issues that are unlikely to be easily resolved? Thanks for any information you can shed.

I'd like to go with the Black due to cost and other factors, but if this cape isn't compatible, it's not so easy to do.) -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] USB errors (and hotplug work-around)
Hi，I have the same issue with musb babble interupt. some low speed mouse can enumerate normally on my box, some mouse will always fail. For the failed mouse, there is always a babble interrupt, and the host mode lost(DEVCTL is 0x98). But I can work around with a externsion cord(about 1.5m), all the failed mouse can work in this case. Could you give me some hint for debugging this problem? I think it may be the bug with mentor's USB ip. On Monday, October 28, 2013 11:27:09 PM UTC+8, Shi Bai wrote: Erm, ok.

It's likely they're stuck in a SUSPENDED state for some reason. I haven't configured pulseaudio on my Bone yet, but on my Pandaboard I had to change the /etc/pulse/daemon.conf file so that it used resample-method=speex-fixed-3 instead of speex-float-3. If those ideas don't get you any further, try turning on more debugging information when you start up PulseAudio and give us a log dump. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: BeagleBone Black: Ethernet transmits packets but does not receive them
On Sunday, July 7, 2013 1:00:28 PM UTC-6, eskimobob wrote: I too have seen the problem both with Angstrom and Ubuntu (13.04). RobertCNelson suggests: I believe it's a problem in the cpsw ethernet driver. (see above). Presumably both Angstrom and Ubuntu pull in the same low level driver. It is not clear (to me at least) whether that means it is a problem which the community can/should fix or whether it is something that TI need to be made aware of so that they can fix it. Can anyone clarify? CPSW refers to the ethernet subsystem in the SoC, which includes a VLAN-aware 3-port switch, two MACs, a timestamping engine for IEEE 1588, and a DMA-based host interface along with various glue. It's all documented in the TRM, so theoretically anyone could fix it, but it's a little less straightforward than your typical ethernet interface. Really nifty hardware though, if you can get it working right. I've written and debugged a full driver suite for CPSW in the context of another TI SoC and another OS, so I could probably track this problem down if I can get some time to familiarize myself with the Linux drivers. It's pretty easy to get it into a state like this where the host port DMA engine is wedged in one direction, as there's a little ownership handshaking dance you have to do with the DMA descriptors and the documentation on it is a little vague in some cases, and it will kill the engine if you get things in an inconsistent state. Luckily it stores the reason for wedging when this happens, so it *might* be relatively easy to diagnose. There are also various opportunities for wedging things in other places, though, so we'll have to see what's really happening. Anyway, I'll try to check it out in the next couple of days and I'll report if I make any progress. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Help for program port COM
Hi all,
I would communicate with an IHM by my BBB, the BBB is connected to my pc by
the USB client and i have a little electronic card containing 2 port COM
connected on my BBB by the USB host.
So i have see than the BBB is connected to the PC by the port COM13 and i
have make a little program for communicate with the IHM:
the program:
#include iostream
#include stdio.h
#include termios.h
#include unistd.h
#include stdlib.h
#include fcntl.h
#include string.h
int main()
{
char buffer[8]= ;
struct termios options;
int fd,reception;
std::string code = ;
unsigned char nombre =0x01;
char P1_Etat = 0x00;
//char[] P1_Led new char[3]={ 0x01, 0x00, 0x00 };
char c;
fd=open(COM13,O_RDWR | O_NOCTTY| O_NDELAY);
if(fd0)
{
printf(problème port serie\n);
exit(-1);
}
else
{
printf(port serie %d ouvert\n,fd);
tcgetattr(fd,options);
cfsetospeed(options, B9600);
options.c_cflag |= (CLOCAL | CREAD);
options.c_cflag = ~PARENB;
options.c_cflag = ~CSTOPB;
options.c_cflag = ~CSIZE;
options.c_cflag |= ~CS8;
tcsetattr(fd, TCSANOW, options);
printf(fin de la configuration\n);
/*if(code == 1222)
printf(code bon\n);
else
printf(code pas bon\n);*/
printf(envoie des données\n);
if(write(fd,nombre, 1)0 )
printf(erreur);
printf(fin de l'envoie\n);
fcntl(fd,F_SETFL,8);
reception=read(fd,buffer,100);
printf(nb de caracteres lu: %s\n,reception,buffer);
if(reception==-1)
printf(erreur lecture port \n);
printf(fin de la réception);
}
close(fd);
}
But if i connect or not the IHM i have always the message problème port
serie .
How i can solve this problem ? i need to change COM13 by the port COM of
the USB host? what is the number for the usb host?
Thank you

Re: [beagleboard] USB errors (and hotplug work-around)
Hi Sword, I haven't got time to touch BBB recently. Most of my time devote to testing of some other device. Frankly speaking BBB more or less having the least stable USB with 3.8 kernel. There was a patch in this thread indeed helped somehow but still it gives trouble when it want. From the first day we understand the USB is quite sensitive to current draw or whatever, we have been using separate power from day 1 and have tested using extension cord of more than 10m which didn't really cause much difference IMHO. Sorry not able to provide much useful information, will definitely revisit here when I got time to play with BBB again. Meanwhile set mpurate indeed helped quite much with the old kernel.

poor Linux support of TIs Starterware? not sure I understand On Friday, November 8, 2013 7:52 AM, levipear...@gmail.com levipear...@gmail.com wrote: On Thursday, November 7, 2013 11:59:10 PM UTC-7, Satz Klauer wrote: On Thu, Nov 7, 2013 at 9:11 AM, levip...@gmail.com wrote: I was able to get that toolchain working and run a couple of basic programs in an emulated (via qemu) ARM M3 platform. Really, a microcontroller is the biggest thing you'd *really* want to write all the code for as a hobbyist. Digging through TRM details and RAM datasheets to figure out the correct timing parameters to program into your SDRAM controller is really not a lot of fun, and you'll never have the time to get a fraction of the BBB's peripherals up and running without taking advantage of a LOT of pre-written code. BBB is for several reasons the best solution for me. And what I try to do is not as complex as it sounds, I just want to access some GPIOs, Ethernet and - perhaps - UART. All the other things like USB, LCD/HDMI, SPIs and whatever is available on the board is not required. Meanwhile I have some code running on it - most troubles have been caused by build problems due to poor Linux support of TIs Starterware. Anyway, thanks for your thoughts! I actually wrote, with a small team, a set of drivers for the CPSW core that makes up the Ethernet support in the BBB, although my code actually ran on a different SoC. It was not a barebones driver, as it needed to interface with the timestamping engine to support PTP, and it was written for QNX rather than a no-OS environment, but it's at least an order of magnitude more complex than writing a UART driver or GPIO access. The BBB's SoC actually has a 3-port Ethernet switch inside, and the host port is controlled via a DMA interface while the RJ45 on the board is connected to one of the external ports. Even if you've had experience writing ethernet drivers before, you are likely to catch a few snags on this one. I don't know exactly what Starterware provides for you, and it may be enough to get all the grungy system configuration and basic drivers going, but everything is about 10x harder with a complex and featureful SoC than it is on a microcontroller. But if you're set on using the BBB for your bare-metal programming experiments, you're sure to learn a lot (and much of it through hair-pulling frustration), so I wish you luck! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Beaglebone Black freezing, USB related?
We have seen similar issues with USB devices on the BBB and are pretty mystified. We suspect a low-level bug in the USB drivers. Did you ever get a good resolution? BTW, on the HDMI console you will probably not see kernel panic messages- they are usually brought out only on the serial header, for which you will need a 3.3V USB/serial FTDI adapter. We also see lots of warnings and USB connect/disconnects in the system logs.

I think learning systemd is worthwhile, as it is a much more powerful system than sysvinit. It's also the default init for Fedora, Arch, and several other big distros. Ubuntu uses an alternate init system called Upstart that is also more powerful and flexible than sysvinit. Both allow you to explicitly model the actual dependencies between services that run, so everything gets initialized in order but as quickly as possible. Upstart and systemd can both significantly cut down on boot time, but systemd goes even further by also taking on the role of inetd, which will open sockets on the ports that services will use in anticipation of starting the service, and hand the sockets over when the service is finished starting. You can use this to trigger the starting of services as well. For example, if you're tight on resources, you can have systemd listen on port 22 in place of a ssh daemon. It won't actually *start* the daemon until someone connects to the port, though. And if you have a service you've written that requires other resources to run, it will ensure your service will start as soon as those are available. I've spent a lot of time pulling my hair out trying to resolve nondeterministic startup issues in a systemvinit-based embedded system. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Unable to Launch getting started page. After updating
Also I'd like to know which OS is currently the best for BBB? Should I stick with Angstrom? I'm a total Beginner mind you. On Friday, November 8, 2013 3:17:22 PM UTC-6, sid2013 wrote: I recently updated the Angstrom image on the BBB to the latest one. about a week ago, everything worked, even with the new image installed. The startup page worked. The device showed up on the port scanner app. I could use Putty to SSH into it. But today when I connected it, I am not able to get the SSH to work, the getting started page doesnt show its connects, neither does the port scanner detect it. The BBB seems to be working as I am getting the Pulsed LED as usual and seems its booted okay. I recently installed Vmplayer and eclipse on my desktop and spend the last couple of days figuring out how to install eclipse on Ubuntu through VMplayer. I was able to SSH back then through Ubuntu on to my BBB. I added a folder on the BBB through eclipse. today its stopped working. I dont know if installing one of the above software has modified any drivers or changed anything on the BBB. Should I try to use the same image of Angstrom I previously used on the uSD and reimage it? Or is there any better explanation to this. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Can't get BeagleSNES to work on BBB
Hello, first time using a BBB, and I've hit a wall. I'm good with Arduino toys and before switching back to Windows 7 I used multiple Ubuntu machines for about 3 years. So some of this BBB stuff isn't too far fetched for me. I bought the board from Adafruit about 2 weeks ago now for the soul purpose of getting BeagleSNES to work on it. From what I can tell, the SD card isn't getting written correctly or the Beagle can't read it as it should. I followed the getting started for BBB. I was able to plug it in and see it and then use Putty to log in as root. I also downloaded the latest software for it, imaged that onto an SD card and the update went fine, although it took about 65 minutes. Much longer than the caution, may take 45 minutes warning suggested. After plugging it back into my Windows 7 machine it looks fine, so the update seems to have worked, so my SD card burning ability is fine, and the BBB can read the card. So I download the full BBB image, write that to a card, plug it into the BBB, plug in the miniUSB cable to Windows, and all I get is a unique blink pattern for about the first 10 seconds on power up. After that, its just the heartbeat pattern. Windows never sees any partition, so I can't copy my roms to it. Basically it looks frozen somewhere. I checked the MD5 hash whatever code and it is a match for the file from Sourceforge. I try just plugging everything into the TV anyways (2 different TV's) and there is nothing. I follow the instructions closely and repeat, nothing. I deviate a little and try resetting or holding the boot button longer, nothing. Just a heartbeat and no screen or sound action. Then I go back and reburn the image to another 4Gb card, nothing on Windows or at the TV. I redownload the zipped image, rewrite both cards, nothing. In summary, a whole lotta nothing :) It seems like all the pieces have proven they work somehow, except the actual BeagleSNES image, which I downloaded twice and re-wrote to multiple cards, multiple times. Now I am downloading Android and going to burn that to another card to see if that will work. If that works for me, then what? Is BeagleSNES working with the latest of everything? I assume it is or I would be able to find more problems in searching this forum, but I didn't. Should I try to do a complete format of the microSD card before writing the image to it? I don't think that should matter. Should I try getting an 8Gb card? I saw on some write ups that 4Gb is close and might not always work for other images. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Beagle Bone Black DC Power and Battery Cape
Hello everybody, I want my BBB keeps ON always although DC power supply fails. I am planning to use the BBB with the Battery Cape, but I am unable to find if it is possible. The main idea is to power ON my BBB from DC all time and when power supply goes down, the battery cape act as a backup battery without system restarting. My question: Is possible to do it? or, do I need to use a different circuit (of battery backup) that allows that?

I have no idea why I can't connect with your images, but without being able to connect, I have no way of figuring out what is going wrong. Any thoughts on uEnv.txt not being compatible. Any thoughts about the best way to try and get a serial usb link going? I will keep trying, but am totally lost on what to do. Everything seems to be going right until I try to login in over the internet. Your image seems to boot up fine, with the lights doing the right things, and booting down after 10 seconds when holding the reset key down etc., just can't get into it over the ethernet. -Ken On 13-11-07 06:00 PM, Robert Nelson wrote: On Thu, Nov 7, 2013 at 4:49 PM, Bit Pusher ken.w.mar...@gmail.com wrote: I am interesting in downloading and upgrading my kernel to Linux ubuntu-armhf 3.8.13-bone28 from Linux ubuntu-armhf 3.8.13-bone20.
