Any help?

"bone" kernels only support uio_pruss..

remoteproc_pruss is NOT mainline, thus the 'bone' kernels don't support it..


Hello Robert,
Thanks for your fast response.
Is it then possible to switch to TI kernel from the board or the best is to recompile new image on host computer from


Dear Robert,

I have tried to ti Kernel as the following but I got these errors…:

root@beagle:#/opt/scripts/tools/ --ti-rt-channel --lts-4_14
info: checking archive
ERROR: The certificate of ‘’ is not trusted.
ERROR: The certificate of ‘’ hasn’t got a known issuer.

Ho wto solve it?

Hi Robert,

I have checked my clock on my board, everything seems ok, see above.

I don’t understand why I have this certificate error?

Any help how to solve it?
