I never saw this reply. I know it is years later, but that was the output of running the Xenomai testsuite on a Udoo Quad. (ie, proof that Xenomai...
Are you communicating data or events? In the latter case you could consider linking IO pins together. There is very little overhead that way, but...
It is with Xenomai. I have a working (ish) Xenomai kernel, compiled from the source here: https://github.com/andypugh/Udoo-Xenomai/tree/xeno...
Quick intro: I am Andy, based in the UK. I sold my first program in 1984, but I have never been a professional programmer. Currently I work as an...
Reading PWM is likely to be expensive computationally. If you can use interrupts and time-stamp them, that is probably the best way. Polling the...
I eventually figured out two things: 1) Serial Tools on Mac is not the best tool for working at the serial terminal, it does not do terminal...
I am trying to boot the kernel with isolcpus=0 in an attempt to improve latency with the Xenomai kernel. As far as I can tell the way to do this...

Re: Failed compile. Syntax error during make Yes, absolutely. If compiling on the actual Udoo you can delete the cross-compiler and just: make...
HDMIPi isn't available yet. (also, in case this wasn't clear, it's not a touchscreen)
Re: Failed compile. Syntax error during make The setsecoversion is a permissions thing. I can't recall if it is because the file is owned by...
As a third alternative, this worked for me: sudo apt-get install --reinstall language-pack-en . I don't know if I needed the sudo . I don't know...
To not answer either of your questions: I am trying to get Xenomai working. However I am a bit of a fumbling hacker, so probably not the person...
I have managed to successfully compile and launch the kernel from the git archive. There are a couple of quirks in the SSD Ubuntu image that make...
That explains it, I guess. Still no closer to figuring out how to get the compile to work. Is there a step-by-step guide anywhere, starting...
http://pastebin.com/6FMwPg8t No error at the end, but reading back there is a fatal error at line 558. Hard to tell success from failure. if it...
Re: I am kickstarter backer and I still do not get my UDOO q It's bad that he needs to. Mine eventually arrived, (a few days ago) and I can...
Have you considered LinuxCNC as the controller? Not that anyone has it working on the Udoo yet, but it runs on BeagleBone, and can handle odd...
http://hdmipi.com/ Might suit. Aimed at the RPi, but I don't see why it wouldn't work with Udoo.
115200bps is likely to be much too slow, that would take about 1mS to send 20 bytes of update data. I was hoping for something at least an order...
