This PR aims to add support for the BeagleBone AI running
Linux beaglebone 4.19.94-ti-xenomai-r64NOTE The necessary BELA Cape overlay for BeagleBone AI can be found here: BBAI-BELA-00A1.dts
Feature List:
libprussdrvon the Am335x.Limitations:
Linux beaglebone 4.19.94-ti-xenomai-r64) crashes on boot, and the board needs to be reset a couple of times to properly boot.IRQ_CROSSBARSwhich me and the Bela team have been working on for a few days. This may take some more time to implement. (however, this shouldn't be much of a deal-breaker for most users)So, at the current stage, the only option is to manually update to the xenomai patched kernel x4.19 using one of the on-board scripts, and then one can source compile BELA using some basic instructions that I have provided on my blog.
