[beagleboard] Re: How to turn on/off GPIOs in BBB
Pad control registers can only be changed in kernel space. You could write a kernel driver or do it the right way and use device tree. See https://github.com/nomel/beaglebone/tree/master/gpio-header If you don't want to use it directly, you can use the generated files as an example. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Is there a 'latest stable build' of Angstrom available, and changed regularly?
I have just got my Beaglebone Black and (being a long time Linux user, from the early 1990s) was looking for a sensible list of Angstrom versions for the Beaglebone Black but I can't really find one. Is there a repository where one can find the 'current' version of Angstrom for the BBB? It happily tells you It is highly recommended that you always use the latest version of the Software. on elinux but there doesn't seem to *be* a latest version of the Software. The link it gives to Updating the software tells you how to do the update and how to see what version is installed but there's no clue as to how to find stable, new versions. Also, can one update/upgrade 'off the net' from the Angstrom command line or does one always have to go through the loading to SD card and flashing process? It would be much more user friendly to be able to do it from the BBB command line. -- Chris Green · -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: GPIO does not turn on LED
Hi Matt,
your dts seems not to be complete.
Please append following code after your existing fragment@0 section:
fragment@1 {
target = ocp;
__overlay__ {
/* avoid stupid warning */
#address-cells = 1;
#size-cells = 1;
gpio1_16_test {
compatible = bone-pinmux-helper;
pinctrl-names = default;
pinctrl-0 = bb_GPIO1_16_pins;
status = okay;
};
};
};
Now you should get the expected value:
pin 16 (44e10840) 0007 pinctrl-single
(I successfully checked the overlay on my bone)
regards
Ralf

On Thursday, February 13, 2014 9:58:03 PM UTC-6, Walter Schilling wrote: Board members: I've got an interesting problem that I'm trying to come up with a solution for. I am going to be teaching a class next quarter on the Beaglebone Black. Students will attach their bones to a network and program them remotely over ethernet. Code will be developed on a virtual machine running Linux and then connected via sftp to the board. However, the students will only have a bone and a prototyping cape available to them. WHat I am trying to figure out is the best way for them to determine the IP address of their board. By default, I know that the boards use dhcp to get an ip address. However, without a display, it's somewhat hard to get an ip address. Is there an easy way, maybe by using the usb connection, that students can figure out the IP address of the board so they can remote to it in an appropriate fashion. I've thought about simply pinging the boards, but with multiple boards on the network, that would only indicate that a board is connected, not that their board is connected. I suppose I could go to fixed IP's, but that would require them to change the SD card, which at first I'd rather use stock until they have gotten their feet wet. Any ideas or suggestions?

[beagleboard] php+postgresql on Angstrom with nginx
I'm trying to set up a php+postgresql+nginx stack on Angstrom (on the BBB). I have nginx serving me php pages, and I have postgresql, but I can't seem to get php and postgresql talking. Usually, one can do a package manager install of php+postgresql, but opkg doesn't offer such an option. The alternative is to build php from source with pgsql enabled, but I'm trying to avoid that since I fear it will mess with the nginx-php settings, and might just make a mess of things.

The one's I get that don't run have flags set to 0x202, old ABI, soft float. Is there a good reason why the newer kernel can't run the older binaries? Are the ABIs that different?

[beagleboard] BeagleBone Black Webcam
Hello all, Sorry for the long message, but I want to include all the details I thought were necessary. I am extremely new to Linux, but I have recently purchased a Beaglebone Black, and I am trying to set up a webcam server on it. I have tried to follow several tutorials online, but none of them have worked, because I cannot get the webcam to work. I have a Logitech C525 HD webcam, which is on the list of supported webcams (http://www.ideasonboard.org/uvc/). I am running Debian 7 (wheezy) with Linux Kernel 3.8.13-bone37. I have installed LXDE so I have a desktop, and VLC to check the functionality of the webcam. I am booting off of a 16GB micro SD card. The Beaglebone is being powered by 5 volts via the barrel connector and a power supply. The webcam, keyboard, and mouse are connected to a powered USB hub. The *lsusb* command returns “Bus 001 Device 003: ID 0460:0826 Logitech Inc” whenever I have the webcam plugged in; so I know the camera is being recognized. However, when I run the *ls /dev/video** command, I get “ls: cannot access /dev/video*: No such file or directory”. This seems to be what VLC is looking for, so it doesn’t see the webcam. When I run the *dmesg|tail* command, none of the entries mentioned anything about video or the UVC driver. I ran *sudo modprobe –v uvcvideo*, then I ran the *dmesg|tail* command again, and this time I got 2 additional lines 1) usbcore registered new interface driver uvcvideo 2) USB video class driver. I apparently have to enable the uvc driver after each restart, but I still don’t get anything when from the *ls /dev/video** command. I should also mention that this is my current configuration, but I have also tried this with Ubuntu 12 and Ubuntu 13 (both installed with instructions from (http://elinux.org/Beagleboard:Ubuntu_On_BeagleBone_Black). I get the same results no matter what I do. I have also tried several other webcams that were not on the list of supported webcams, with the same results. I know the webcams work with Linux because I have tried them on an old laptop that is running Mint 12, and they worked just fine. Since the webcams work in Mint, and many other people have been able to get them working on the Beaglebone, I am obviously missing something, but I don’t know where to go from here. Any help would be greatly appreciated.

Thanks On Thursday, January 30, 2014 3:17:40 PM UTC-5, Matthew Witherwax wrote: If you bypass OpenCV and capture directly like we did, you should test to see if you can capture successfully in YUYV format. OpenCV can convert YUYV to a Mat with less than 3% cpu use. If you capture in MJPEG, you will see cpu use of 90% or more to convert the image to a Mat. This isn't so bad on the Wandboard because it only consumes one core, but can be intense on the single core BBB. I can tell you from testing with the Wandboard Quad, it can push 30 fps in YUYV over USB. However, it is only possible to stream from one camera at 30 fps in YUYV. In short it is a tradeoff. You can either saturate the USB and save processing or save bandwidth and increase processing. Something to consider depending on your needs.

The fix Matthew and I have used is to just use our own video4linux capture code. You might be able to modify the OpenCV source code, but the capture code is difficult to follow since there are so many layers of abstraction.

[beagleboard] Re: Motor Controller for BeagleBone Black
Hi Morgan,
How is the Motor shield wired to the beaglebone? I see that you are using
P8_9,10,15, and 16, wondering what pins on the shield are the hooked up to.

[beagleboard] Re: BBB and element 14 BB-View cape
Did you get it working? I had a similar issue with the 4.3 inch version. First off insure you are using 5v adapter, usb doesnt put out enough power to power both. If you are booting up and only see the red led0 flashing, then it is your cable. Also I read somewhere for the 7inch, you need to configure it using putty/ssh connection to work properly. Just follow directions for this on http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone Should cover this on the full version of the user manual.

[beagleboard] USB Serial issues on Beaglebone
Hey All, I've just tried to move my BeagleBone from the TI provided BSP (Argo Linux 3.2 Release 04.06.00.11) to one of the newer community kernels from https://github.com/beagleboard/kernel. I'm not using any distro, just a busybox based rootfs. My motivations for moving to the later kernels are to gain Device Tree and a bunch of other drivers for some I2C devices as well as the TPS PMIC backlight (ultimately this will be used on a Beaglebone based custom design). I figured it would be easier to move forward that to reverse engineer these drivers into the old 3.2 kernel. Everything seems to work, except for one of the USB use cases I'm interested in. I'm able to mount a USB stick and copy a couple of gigs of data between the two without any issues. However, when I try to communicate with a CP2102 USB UART I very quickly seem to hang the driver. This worked fine in the old 3.2 kernel. It seems to send a bunch of data (but It doesn't seem to arrive on the other end of the UART) and then the TX buffer fills and causes my sending test app (https://gist.github.com/anonymous/1f2b2d5bca0041aa42d6) to hang. When I pull the USB cable, I get a kernel panic somewhere in the DMA driver waiting to clear the FIFO. I've tried this on 3.8, 3.12 and 3.13 all with similar results. 3.8 panic:https://gist.github.com/anonymous/3797f93521ce931f82e6 3.13 panic: https://gist.github.com/anonymous/35c4c49e5a9514d2adb8 I'm using the stock am335x-bone.dts for each of the kernels. I've also removed the USB support from u-boot (2014.01) to make sure no contamination got through. Now although this only manifests with the cp210x driver (at least for me), I've done a diff between 3.2 and 3.13 versions and I can’t see anything too significant that’s changed. I'm thinking it's somewhere under the hood within the musb core/platform bindings, which is my next avenue of investigation. However I figured I’d see if anyone else has run into any problems like this, and was wondering if someone could answer a couple of questions I have: * What is the recommended kernel to be using now? Should I stick to 3.13? * How much verification/what verification has been done on the USB Host to define it as working as is declared in README.md Cheers for any help Chris -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] BBB kernel 3.12.10/ GPMC
I am testing kernel 3.12.10 on the BBB. The system boots without issues. To be able to use the GPMC bus we must disable eMMC and HDMI. I did modify the uEnv.txt accordingly. I also modified am335x-boneblack.dts and set status=disabled in section mmc2. After that I can successfully load my .dts file without any errors. I also checked dmesg. But when trying to access the GPMC nothing happens on the GPMC signals. The same .dts file works without issues in kernel 3.8.13.

But it doesn't work well because the mouse pointer is shifted (I use a touch screen)..

That´s what I'm up too. I´m trying to search a way to cross compile to X11. If you find any solution, please post here. I´ll do the same, maybe a video guide. I found that beagleboard has two qt demos. The proper qtdemo and qtdemoE. The qtdemo is launch over X11 and qtdemoE must be launched with -qws option. I couldn't find anything about how qtdemo was made. Did you try the tslib calibration solution? I still don't have my LCD7.

[beagleboard] Re: GPIO does not turn on LED
Matt, I have not a lot of device tree experience. Currently I design a FPGA-based cape for motion control. The cape must be supported by device tree. So I was forced to get an basic understanding of the dts mechanism. I took some simple and some complex dts sources from kernel tree and studied the description. Sometimes it is helpful to grep some description keywords in the kernel source or in the web to get an better understanding of the mechanism. There are a lot of device tree guides floating around. This one might be a good starting point http://www.circuidipity.com/bbb-dt.html and contains some more useful links. But be aware some descriptions get sometimes outdated and can not be taken 1:1. regards Ralf -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

RE: [beagleboard] learning ARM assy with BBB
Hi DD, I know exactly what you mean when you say that your assembly software rocks. And I am with you when you talk about the , mountains of dry meaningless documentation Only someone who has written good assy knows what assy can do and what C can never hope to. Every one said that a 8051 running at 30 MHz could never transfer a bmp file from an SDHC card to an LCD at a reasonable speed. They are wrong. With just one 4 x 2 input nand gate I find a way to do just that using the built in SPI port on the 89C51AC3. The data is setup and goes directly from the memory to the LCD. The processor only controls the clock. The rest is assy. I will soon start a blog of my own where I promise to fleece C, Linux and all that trash. I have nearly given up on this whole business. Besides, I don't want to learn/code in C or any other higher lingo any more. And I am no fan of Linux either. I see no need for it. From the bits I know, and looking at C code, I can tell that it is an impossibly stupid language. I am sure that you are aware that it started as a joke. ( look for C started as a joke with Google.) I am reading the Cortex manuals and hope to be able to write good Assy for this processor. I have no need for the | packages Can one imagine a language where even the experts cannot agree as to what a particular combination of operators forming a statement means. And like marketing warriors they claim that the minimalism of C is a prized feature. In fact a deadly weakness Bah. I hold that Assembly is an undervalued stock. And C's much vaunted cross platform capability is oversold. A lingo where such basic elements as the very size of variables is suspect. Porting C code from one platform to another is a joke, albeit a cruel one. And it is not true that my work was some low grade S*4#$T. One of my proud creations lives at 20,00 feet and the other moves at 600MPH at under 500 feet. So I know my stuff. I have been probing at some of these heroes who talk incessantly on the forums about the latest software they have mastered. I suspect that they actually in fact understand zilch. Some of my pointy questions in a way that suggests this conclusion. And do you want to know why the experts don't tell us how? Because they don't know it themselves. Read up the Sitara manuals. They are long but easy to follow. I think I should with luck be able to handle the Sitara. I have given up on the Cubie though. Thanks for reading this harangue. And stay in touch. I will send you the link to my blog whan I have it up. The skunks have given permission Azzythehillbilly.

BTW, I hear a lot the term 'cape', what exactly do you mean by that? Second of all, Thanks a lot for the Fragment@1 addition! It works great :) I read the article you attached, it explains the motivation but does not go into details, but it was still helpful to see the big picture.

The cape must be supported by device tree. So I was forced to get an basic understanding of the dts mechanism. I took some simple and some complex dts sources from kernel tree and studied the description. Sometimes it is helpful to grep some description keywords in the kernel source or in the web to get an better understanding of the mechanism. There are a lot of device tree guides floating around. This one might be a good starting point http://www.circuidipity.com/bbb-dt.html and contains some more useful links. But be aware some descriptions get sometimes outdated and can not be taken 1:1. regards Ralf -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Reference for Enabling GPIO Interrupt
Hi again, To be more focused, I learned that for setting an interrupt you need to simply set a priority if desired, and necessarily clear the desired *INTC_MIRn *bit. However, when the Interrupt is generated, how do I define the Interrupt Handler Routine where I'd write the desired interrupt processing - e.g. turn on a LED when an interrupt is generated? I mean, how do you know how to name the Interrupt Handler's function? Thank you. On Monday, February 17, 2014 10:32:05 AM UTC+2, matt wrote: Hi, I'm trying to work with Interrupts, firstly on GPIO.

[beagleboard] Re: Is there a 'latest stable build' of Angstrom available, and changed regularly?
I imagine you have found this site http://beagleboard.org/latest-images, that is where the official images are. I know that they haven't been updated recently, but I hear that a Debian version is coming along nicely, should be out soon. The kernel in the most recent official image might be outdated, I would check out Robert Nelson's Github page, checkout the latest 3.8.x kernel, and put that onto the beaglebone. That should get you the most stable image to start working with. I would also keep an eye out for the next official image, I'm hoping it is out soon :).

[beagleboard] Re: Attention if order LVDS-Board from chalk-elec!!!
Hello Mike, This question is not really related to me, because I'm trying to resolve situation with missed orders as a third-party person. Anyway, here is my point of view on technical support: 1. ChalkElec sells open-source products, you can get schematic and Gerbers from their website to better understand how to use it in your project. 2. They also offer a lot of How-To and test images that allow to check product functionality. 3. Every product has warranty and can be returned in case of any problem that can't be solved on customer side. 4. Also, I know that Ace do his best to answer technical questions that are mostly related not to hardware, but to specific software issues on customer side. I don't know what was the problem in your case, so please send email to me with description - I will try to help somehow.

Just so you know. Much of the Debian and Ubuntu documentation will work for both. Debian also has a ton of information / documentation out there. All you have to do is google. I like Debian because I have been using it for years and it is very solid. Debian on the BBB has also been very solid in my experience.

Re: [beagleboard] BeagleBone Black Webcam
If you're using Roberts instructions for compiling the kernel, did you poke around in menuconfig to see if the cam needed a specific driver compiled in ? Also I would recommend if this is an option that you actually compile the driver module into the kernel ( * ) instead of as a module ( [M] ). Passed this, sorry I have no further advice to add.

I am extremely new to Linux, but I have recently purchased a Beaglebone Black, and I am trying to set up a webcam server on it. I have tried to follow several tutorials online, but none of them have worked, because I cannot get the webcam to work. I have a Logitech C525 HD webcam, which is on the list of supported webcams (http://www.ideasonboard.org/uvc/). I am running Debian 7 (wheezy) with Linux Kernel 3.8.13-bone37. I have installed LXDE so I have a desktop, and VLC to check the functionality of the webcam. I am booting off of a 16GB micro SD card. The Beaglebone is being powered by 5 volts via the barrel connector and a power supply. The webcam, keyboard, and mouse are connected to a powered USB hub. The *lsusb* command returns Bus 001 Device 003: ID 0460:0826 Logitech Inc whenever I have the webcam plugged in; so I know the camera is being recognized. However, when I run the *ls /dev/video** command, I get ls: cannot access /dev/video*: No such file or directory. This seems to be what VLC is looking for, so it doesn't see the webcam. When I run the *dmesg|tail* command, none of the entries mentioned anything about video or the UVC driver. I ran *sudo modprobe -v uvcvideo*, then I ran the *dmesg|tail* command again, and this time I got 2 additional lines 1) usbcore registered new interface driver uvcvideo 2) USB video class driver. I apparently have to enable the uvc driver after each restart, but I still don't get anything when from the *ls /dev/video** command. I should also mention that this is my current configuration, but I have also tried this with Ubuntu 12 and Ubuntu 13 (both installed with instructions from ( http://elinux.org/Beagleboard:Ubuntu_On_BeagleBone_Black). I get the same results no matter what I do. I have also tried several other webcams that were not on the list of supported webcams, with the same results. I know the webcams work with Linux because I have tried them on an old laptop that is running Mint 12, and they worked just fine. Since the webcams work in Mint, and many other people have been able to get them working on the Beaglebone, I am obviously missing something, but I don't know where to go from here. Any help would be greatly appreciated. There are known usb issues with the 3.8 kernel.. Please test with either Ubuntu/Debian base microSD: http://elinux.org/BeagleBoardUbuntu http://elinux.org/BeagleBoardDebian Then, cd /opt/scripts/ git pull ./tools/update_kernel.sh --beta-kernel (reboot) To pull in a v3.13.x based kernel..

[beagleboard] Re: Beaglebone USB serial issues
Hey, I've done a bit more digging at the problem seems to be that for some reason the TXPKTRDY bit in the HOST_CSR register never get's cleared by the MUSB controller. This is causing cppi41_dma_callback() to schedule work due to musb_is_tx_fifo_empty() stating there is still data in the outgoing FIFO. Consequently the callback schedules cppi_trans_done_work() which also uses musb_is_tx_fifo_empty() which then reschedules itself if there is still data. Thus the cppi41_trans_done() - musb_interrupt() - musb_host_tx() are never called so the USB controller never gets released. You can see this through the dmesg.

I'm not using any distro, just a busybox based rootfs. My motivations for moving to the later kernels are to gain Device Tree and a bunch of other drivers for some I2C devices as well as the TPS PMIC backlight (ultimately this will be used on a Beaglebone based custom design). I figured it would be easier to move forward that to reverse engineer these drivers into the old 3.2 kernel. Everything seems to work, except for one of the USB use cases I'm interested in. I'm able to mount a USB stick and copy a couple of gigs of data between the two without any issues. However, when I try to communicate with a CP2102 USB UART I very quickly seem to hang the driver. This worked fine in the old 3.2 kernel. It seems to send a bunch of data (but It doesn't seem to arrive on the other end of the UART) and then the TX buffer fills and causes my sending test app (https://gist.github.com/anonymous/55ab3051827aeb698f95) to hang. When I pull the USB cable, I get a kernel panic somewhere in the DMA driver waiting to clear the FIFO. I've tried this on 3.8, 3.12 and 3.13 all with similar results (3.13 panic = https://gist.github.com/anonymous/12ef2a1223f7a953f293) I'm using the stock am335x-bone.dts for each of the kernels. I've also removed the USB support from u-boot (2014.01) to make sure no contamination got through. I've also tried to disabling the USB DMA support in the kernel .config. I've found that I get the exact same symptoms if I use a different USB UART ftdio_sio, so I think the problem is somewhere under the hood within the musb core/platform bindings. I figured I’d see if anyone else has run into any problems like this, and was wondering if someone could answer a couple of questions I have: * What is the recommended kernel to be using now? Should I stick to 3.13? * How much verification/what verification has been done on the USB Host to define it as working as is declared in README.md Cheers for any help Chris -- For more options, visit http://beagleboard.org/discuss --- You received this message

Thanks for all the ideas. This is the direction I plan on going now that I've made it work. As a side note, if you are trying this, make sure you have your VM in Bridges mode and not NAT mode. NAT will not work, but it works fine once you go into bridged mode.

[beagleboard] After hotplug ging USB mass storage device system hang.
Hello, I am using a Beaglebone black board wuth ubuntu 12.04 (3.8.13-kernel). My board is working very good with eMMC as well as with with SD card. Problem is when I hotplug a USB mass storage device(pendrive) whole system getting hang. Then if I powered off and again powered ON with pendrive then its working properly and pendrive is also detecting. Problem is only during hotplug.
