I would love to see a simple "echo" rpmsg example for C66 cores using GCC toolchain.That would allow interesting experiments without any proprietary bits.
I tried and failed to get a simple C66 ELF from c6x-gcc to be loaded by remoteproc. I then saw mentions of setting up IOMMU in the linux remoteproc driver and gave up :) Regards, Dimitar On Wednesday, February 10, 2021 at 4:49:49 PM UTC+2 Daniel Block wrote: > Jason (or anyone else), what would you recommend to a person just getting > started programming the C66x DSP cores on the BeagleBone AI board for this > summer of code?
