Hi! I’m trying to enable the PRUSS on my beaglebone running:
Debian Image 2015-11-12
and uname -r
4.1.13-ti-r35
After the boot-up dmesg gives me:
[ 15.756474] remoteproc1: Direct firmware load for am335x-pru0-fw failed with rror -2
[ 15.756559] remoteproc1: failed to load am335x-pru0-fw

[ 15.809512] remoteproc1: request_firmware failed: -2
[ 16.023483] pru-rproc 4a334000.pru0: rproc_boot failed
`
(this is the whole dmesg output)
