Re: [beagleboard] Xenomai master - BBB RCNelson 3.13-bone5 kernel patches
Hello dlewin555 Did you succeed in installing Xenomai on your BBB?

Re: [beagleboard] Xenomai on BBB
Hi Giuseppe ! Did you succeed installing Xenomai? I'am having troubles with it... Well I'm not an expert so I could do something wrong in the procedure / or don't do something. Here is what I did: 1) I download the zip : https://github.com/yapatel/beagleboneblack-xenomai 2) I execute the following script ./build_kernel.sh 3) use eMMC patcher and put it to a microSD card Install Kernel Image to SD card: (requires MMC set in system.sh) 4) I execute the following script ./tools/install_kernel.sh What do I have to do to get Xenomai on my BBB? Did I miss something? Le mercredi 25 septembre 2013 09:12:03 UTC+2, Giuseppe Iellamo a écrit : Thank you very much! This is very valuable help for me!

Re: [beagleboard] Re: PRU FAQ 2013-05-15
Hello, I am also very interesting about this. I need to complete a fast ADC / DAC with some numeric matrix calculation. I thought about using a BBB, and the PRUs seemed to be a very interesting point. The numeric part could be done using Xenomai. Apparently the use of SPI with the PRUs is possible. So can I use SPI ADC / DAC with the PRU? Could anyone be more precise on how to do it? Write SPI drivers for the PRU? If I was not clear enough, tell me :) Thank you very much Le mardi 22 octobre 2013 17:23:11 UTC+2, u.pel...@srett.com a écrit : Hi, Thanks for these informations. But I would like to use the PRU to get data from a fast ADC connected by SPI. I get that there is no example of SPI connection but is it possible ? It seems that the PRU can only access to UART, CFG, eCAP interfaces. Am I right ? Thanks. Ugo Le jeudi 26 septembre 2013 00:05:00 UTC+2, Charles Steinkuehler a écrit : On 9/25/2013 4:48 PM, Mark A.

I've looked at the examples in Jason's post, but more examples on how to do simple things would be helpful. I have some basic example code I tried to comment very well for use as an example of the PRU debugger available with LinuxCNC. It mostly just sets up the timer portion of the industrial Ethernet controller (the only part that's documented) and blinks some LEDs. I tried to provide examples of various assembler features (like using records/structs) as well as use a variety of coding techniques (including a jump table for case logic). Perhaps you might find something useful reading through the code: https://github.com/cdsteinkuehler/linuxcnc/blob/MachineKit-ubc/configs/ARM/PRU-Debugger/pruexample.p ...or if you've got a copy of my MachineKit image you can try running it with the debugger and single-stepping through the code. 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. Or, examples of the PRU talking to things on the i2c or SPI buses. Has anyone gotten the PRU to control a quadcopter? No to both of the above, AFAIK. -- Charles Steinkuehler cha...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
