Re: [beagleboard] Re: first steps to implement a new camera sensor driver in BB-xM...
If you are using ADC adapter which has interlaced output only then you need to make required changes in the kernel/bootloader to set FID pin in P10 socket in BB-xM. Even I have done this changes, it seems the current drivers (CCDC/V4L2) doesn't support the interlaced video input. I mean I couldn't find any driver code who uses FID (Field Indicator - EVen/Odd) signal. Is anyone in the position to confirm this finding? Regards, Ozkan. On Wed, Oct 9, 2013 at 10:20 AM, ozkann...@gmail.com wrote: An important note if you are going to use your own camera adapter card instead of LI5M03, BB-xM camera port (P10) is expecting frame_valid and line_valid signals in VSync and HSync pins. So, you may need to make some design changes at outputs of ADC chip that used in your board in order to satisfy the requirement of BB-xM.

Re: [beagleboard] SSH is intermittently slow (BBB running Ubuntu 13.04 shell)

It is normal. 2013/10/21 Cody Rushing codyrush...@gmail.com To preface this, I'm new to Linux - I picked up a BBB largely to learn more about Linux, networking, web servers, etc. Anyways, here's my setup: BBB flashed with Ubuntu 13.04 shell. I'm using this wifi donglehttp://www.amazon.com/Edimax-EW-7811Un-Wireless-Adapter-Wizard/dp/B003MTTJOY/ref=sr_1_1?ie=UTF8qid=1382404733sr=8-1keywords=wifi+dongle, which Ubuntu supports natively which was nice. So it's connected to my wifi at home, meaning I can SSH in from any device on the same network. Sometimes, it connects quickly and feels seemless; othertimes it's super slow, with like a 5-10 second delay on each keystroke. I've noticed that it can be very quick, then after rebooting the BBB, it will be slow. I've tried different things like connecting the wifi dongle directly vs using a usb hub, leaving the external case on or off, and I can't seem to find a pattern. I'm not sure if this is normal behavior or not. Should I just chalk this up to random network inconsistency? I'm guessing that if the BBB has a poor wifi signal, that will result in slower SSH right? Maybe there's a linux command I can use to check the BBB's connection speed over wifi.

Re: [beagleboard] Audio Cape with Beaglebone Black
Hi, I can confirm that it is possible to achive great audio quality on your BBB with AudioCape. Building kernel without using HDMI patches makes AudioCape works very well. The kernel version I used was 3.8.13-bone28. I belive it is not necessary to disable all of HDMI patches, what excludes HDMI permanently for this kernel. But when somebody doesn't need HDMI at all, this solution is very easy to apply. Thanks for your help.

Re: [beagleboard] Interfacing RF-Transceiver (CC1101 etc.) directly via SPI to Beaglebone
Hello Andrew, It looks like your post gave me some clue. I actually just started out to add CC1101 module on my Ras Pi. Since there is a generic SPI driver on my Ras Pi, do I have to create another SPI driver for CC1101 module? Or just as you said interface the C-code from 8051 to Linux?

I know http://theredblacktree.wordpress.com/2012/08/09/rf24bb/ and other ressources, but can't get an idea if those are more like a proof of concept. For real applications, the CC1101 should be interfaced to: - SPI including automatic CS - an Interrupt - GPIO The configuration of the CC1101 takes some bytewise exchange of data, but after that it's more or less plain frame-download and send or frame uploading on interrupt... CC1101 has 64 byte Tx and Rx FIFOs. As long as you send frames that are smaller than that, interfacing directly from Linux shouldn't be an issue. It's just like you said, SPI and GPIO. The data sheet's pretty decent, too. If you want to send or receive frames larger than 64 bytes, you'll need to empty / fill the FIFOs when the interrupt comes stating that they're close to being full / empty. This may be difficult depending on your RF data rate (ie: at 200 kbps you get 1 ms to react to FIFO interrupts but at lower data rates there may be reasonable time to react). Linux isn't the best at dealing with sub 1 ms actions, a dedicated microcontroller or the PRUSS would be a better fit. If TI / Chipcon made a CC1101 transceiver with 128 or 256 byte FIFOs, that would be great but I don't think such a thing exists. TI / Chipcon, if you're listening, make a CC1101 with 128 byte FIFOs! Please? You can take a look at the CC1110 or CC430 which each have an embedded microcontroller on the same die (CC1110 is 8051 I think, CC430 is MSP430) and then interface either of those to Linux easily via SPI or other interface. -Andrew -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Could you give me some more details about how to interface CC1101 from 8051 to Linux? You'd want to write either a kernel driver using SPI and GPIO (lots of Ethernet SPI controllers have this kind of interface, for reference, or for a reasonable example with exact steps, google for spike spi driver) in order to provide a kernel level interface. This isn't tremendously hard, but if you'd prefer, you could also take a look at using spidev and GPIO from userspace. The performance in userspace likely won't be as good as in the kernel, but the learning curve should be lower if you've not written kernel drivers before. The CC1101 doesn't have an integrated microcontroller, just the CC1110 and CC430 families. Although, recently TI introduced the CC1200 radio which has larger FIFOs (128 byte) and is targetted at those doing IEEE 802.15.4 with sub-GHz radios. If your radio frames are 128 bytes or smaller, and especially if you're doing 802.15.4, the CC1200 is well worth your time to look at. If you're not tied to using TI parts, also have a look at the Analog ADF7023 or the ST SPIRIT1. Both, on paper, are better looking than the CC1101. However, if you have an RF cape for beaglebone the TI modules pop right on, which is handy.

I know http://theredblacktree.wordpress.com/2012/08/09/rf24bb/ and other ressources, but can't get an idea if those are more like a proof of concept. For real applications, the CC1101 should be interfaced to: - SPI including automatic CS - an Interrupt - GPIO The configuration of the CC1101 takes some bytewise exchange of data, but after that it's more or less plain frame-download and send or frame uploading on interrupt... CC1101 has 64 byte Tx and Rx FIFOs. As long as you send frames that are smaller than that, interfacing directly from Linux shouldn't be an issue. It's just like you said, SPI and GPIO. The data sheet's pretty decent, too. If you want to send or receive frames larger than 64 bytes, you'll need to empty / fill the FIFOs when the interrupt comes stating that they're close to being full / empty. This may be difficult depending on your RF data rate (ie: at 200 kbps you get 1 ms to react to FIFO interrupts but at lower data rates there may be reasonable time to react). Linux isn't the best at dealing with sub 1 ms actions, a dedicated microcontroller or the PRUSS would be a better fit. If TI / Chipcon made a CC1101 transceiver with 128 or 256 byte FIFOs, that would be great but I don't think such a thing exists. TI / Chipcon, if you're listening, make a CC1101 with 128 byte FIFOs! Please? You can take a look at the CC1110 or CC430 which each have an embedded microcontroller on the same die (CC1110 is 8051 I think, CC430 is MSP430) and then interface either of those to Linux easily via SPI or other interface. -Andrew -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] GPIO
There is no +5V supply on the processor. So yes it is isolated and if you connect 5V to a GPIO pin, you will destroy the processor.

[beagleboard] BBB, GPMC bus for FPGA FIFO and 3.8 linux kernel
Dear all, I posted a similar post in the TI E2E forum and they said to post it here, so... I have to set the AM3x side to manage the reading phase from a FIFO placed inside an FPGA and I almost lost. I saw several posts which starts as: I have to use GPMC bus and I do not know how to do it., and several posts asking too detailed informations. So, I'll try to be in the midway. I usually write firmware (vhdl), so I am not that expert in software, kernel and driver (frankly speaking, I am not an expert at all). I spent the last two days reading manuals, guides, codes around and what I have understood so far can be summarized in a few steps (by supposing to work with the 3.8 linux kernel): 1) create a .dts file (whit chip-select, output-enable, write enable... settings) 2) compile and install it in /lib/firmware 3) enable it ( in the slot field) 4) Now that you have sort of drivers for GPMC communication, it is possible to write C code to work with it. I saw here http://derekmolloy.ie/beaglebone/ doing something similar for GPIO, so, I guess it could be possible to do that also for GPMC. Something is missing? is that right? And then, is there a .dts template for gpmc that one can just modify to set communication? Is there also some already-tested file for C coding or I should write it from scratch? Thanks a lot for your help. Alberto -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

I've tried different things like connecting the wifi dongle directly vs using a usb hub, leaving the external case on or off, and I can't seem to find a pattern. I'm not sure if this is normal behavior or not. Should I just chalk this up to random network inconsistency? I'm guessing that if the BBB has a poor wifi signal, that will result in slower SSH right?

For example, how does on set up a double buffer between the ARM and the PRU with the PRU interrupting the ARM when it's finished with one buffer and is working on the next so the ARM can refill the buffer. That is totally *NOT* simple and has a *LOT* of places where things can go wrong (race conditions, deadlocks, cache management, etc). I'll probably have code that deals with all of this at some point, but I wouldn't expect it to be a newbie oriented HOWTO code example.

[beagleboard] BBB CryptoCape group
I'm working on BBB Cape that extends the cryptographic capabilities of the BBB, aptly called the CryptoCape[1]. For those that are interested in helping or lurking, I've setup a Google group[2] which is open to the public so feel free to sign up. While this list is amazing, I want a lower-volume and more topic-focused area to talk about adding trusted boot capabilities, crypto acceleration and the like.

Re: [beagleboard] Re: Failure Rate of Beagle Boards
The power related issues are not necessarily the fault of the device its self. It could be a bad ground on your part, or other new software that you've installed or started to use. When the BBB has blinking LEDs ( CPU heartbeat ) this implies that it does in fact work. SO either you're not waiting long enough, or dropbear( assuming ssh ) has lost its mind again. Yet there are other possible causes as well. Get a serial debug cable as Robert suggests, and see what is happenign at the console / uboot prompt.

The second line also runs once per hour, but runs 1 minute past the top of the hour. *NOT* once every minute as you desired. Crond runs *only* once every minute (finest resolution possible), so if you want a cron job to run once every minute, then you need to set the fields as follows: * * * * * /home/root/keep_alive.py cronjob.log And check to make certain that your script actually resides in the directory path you have given (/home/root/). The 'root' account's home directory is /root, not /home/root, so to have /home/root you must have performed a mkdir to create that root subdirectory under /home. Also be aware that plain old users CANNOT run scripts that require 'root' permissions. They must be run out of the system crontab configured in /etc/crontab. Also verify that the permissions are set correctly on your python script so that it is executable. 'ls -al keep_alive.py' will show the permissions. 'chmod u+x keep_alive.py' will turn on the execute bit for this file to be run as the User.

USER/BOOT button 3. power on 4. all 4 leds after 1 min process, led USR3 (eMMC) flashes only few times, then i have normal heartbeat and cpu indicator. botting without microsd still results with led0,1,2 :( does it mean that eMMC is broken? i tried to read dmesg but i havent found anything useful.

Looking at the kernel .config the setting described earlier in this thread is configured as: CONFIG_USB_ETH=m Below is my dmesg output filtered for 'usb': debian@arm:~$ dmesg | grep usb [0.154355] usbcore: registered new interface driver usbfs [0.154467] usbcore: registered new interface driver hub [0.154797] usbcore: registered new device driver usb [1.646463] usbcore: registered new interface driver cdc_ether [1.652718] usbcore: registered new interface driver rndis_host [1.659126] usbcore: registered new interface driver cdc_ncm [1.665920] usbcore: registered new interface driver cdc_acm [1.685532] usbcore: registered new interface driver usb-storage [1.696880] musb-hdrc: version 6.0, ?dma?, otg (peripheral+host) [1.703609] musb-hdrc musb-hdrc.0.auto: pdev-id = 0 [1.708865] musb-hdrc musb-hdrc.0.auto: drivers/usb/musb/musb_dsps.c:468 dsps_musb_init: OK [1.717645] musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) [1.717665] musb-hdrc: MHDRC RTL version 2.0 [1.717680] musb-hdrc: setup fifo_mode 4 [1.717707] musb-hdrc: 28/31 max ep, 16384/16384 memory [1.717906] musb-hdrc musb-hdrc.0.auto: *** mode=3 [1.722953] musb-hdrc musb-hdrc.0.auto: *** power=250 [1.728966] musb-hdrc musb-hdrc.1.auto: pdev-id = 1 [1.734230] musb-hdrc musb-hdrc.1.auto: drivers/usb/musb/musb_dsps.c:468 dsps_musb_init: OK [1.743012] musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) [1.743031] musb-hdrc: MHDRC RTL version 2.0 [1.743045] musb-hdrc: setup fifo_mode 4 [1.743067] musb-hdrc: 28/31 max ep, 16384/16384 memory [1.743238] musb-hdrc musb-hdrc.1.auto: *** mode=1 [1.748282] musb-hdrc musb-hdrc.1.auto: *** power=250 [1.753594] musb-hdrc musb-hdrc.1.auto: MUSB HDRC host driver [1.760016] musb-hdrc musb-hdrc.1.auto: new USB bus registered, assigned bus number 1 [1.768282] musb-hdrc musb-hdrc.1.auto: supports USB remote wakeup [1.768403] usb usb1: default language 0x0409 [1.768462] usb usb1: udev 1, busnum 1, minor = 0 [1.768485] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002 [1.775625] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [1.783200] usb usb1: Product: MUSB HDRC host driver [1.788420] usb usb1: Manufacturer: Linux 3.8.13-bone28 musb-hcd [1.794723] usb usb1: SerialNumber: musb-hdrc.1.auto [1.800700] usb usb1: usb_probe_device [1.800729] usb usb1: configuration #1 chosen from 1 choice [1.800799] usb usb1: adding 1-0:1.0 (config #1, interface 0) [1.801006] hub 1-0:1.0: usb_probe_interface [1.801028] hub 1-0:1.0: usb_probe_interface - got id [1.912044] usb usb1: bus auto-suspend, wakeup 1 [2.035218] usbcore: registered new interface driver usbhid [2.041134] usbhid: USB HID core driver Regards, Andrew.

Re: [beagleboard] Re: Failure Rate of Beagle Boards
Not really scientific, but I have used around 50 Beagles of various pedigree/version. I have only had to return one for repair, and that was I think due to accidentally applying 5V to a GPIO pin. :-( Keep up the good work Gerald et al. :-) Dave.

It could be a bad ground on your part, or other new software that you've installed or started to use. When the BBB has blinking LEDs ( CPU heartbeat ) this implies that it does in fact work. SO either you're not waiting long enough, or dropbear( assuming ssh ) has lost its mind again. Yet there are other possible causes as well. Get a serial debug cable as Robert suggests, and see what is happenign at the console / uboot prompt.

Re: [beagleboard] eMMC broken?
I have no way of knowing for sure. Maybe. Spontaneous combustion is something I have yet to run across on these boards. If you can't flash it, then maybe the eMMC is bad. Only way to know for sure is sending it in.

[beagleboard] Re: SSH is intermittently slow (BBB running Ubuntu 13.04 shell)
You were right about it being a power issue. I turned off power management on my wireless and my signal quality remains high and my SSH connection is fast. Thanks! Just a note, this did not work on the BBB: sudo iwconfig wlan0 power off I get SET failed on device wlan0 ; Operation not permitted. So, a found a solution over at askubuntuhttp://askubuntu.com/questions/85214/how-can-i-prevent-iwconfig-power-management-from-being-turned-on, which was to create an empty wireless hook under /etc/pm/sleep.d by using this command. sudo touch /etc/pm/sleep.d/wireless Do that, then reboot, and wireless should remain high. I'm not sure if I need to worry about heat issues though. At the end of the day, this will be running a web server, so ideally I would want to write a script that keeps the power management on while no requests are coming in, and turns it off when they are. Thanks again! On Tuesday, October 22, 2013 5:20:39 AM UTC-5, hemant...@gmail.com wrote: This could be because of the power management of wifi. Try to disable the power management feature on the wifi adapter. # sudo iwconfig wlan0 power off (replace wlan0 with the name of your adapter) This might heat up your wifi adopter. To verify if this works out, ping any host before and after disabling power management. Are you using USB hub with external power or directly connecting the wifi adapter to the BBB board ?

So it's connected to my wifi at home, meaning I can SSH in from any device on the same network. Sometimes, it connects quickly and feels seemless; othertimes it's super slow, with like a 5-10 second delay on each keystroke. I've noticed that it can be very quick, then after rebooting the BBB, it will be slow. I've tried different things like connecting the wifi dongle directly vs using a usb hub, leaving the external case on or off, and I can't seem to find a pattern. I'm not sure if this is normal behavior or not. Should I just chalk this up to random network inconsistency? I'm guessing that if the BBB has a poor wifi signal, that will result in slower SSH right? Maybe there's a linux command I can use to check the BBB's connection speed over wifi. Any thoughts/help would be greatly appreciated - thanks. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
