Hello! I'm facing an issue with Beaglebone Black PRU. I have successfully compiled a C program for PRU0 and copied it to /lib/firmware with name am335x-pru0-fw. But when I type sudo rmmod pru_rproc and then sudo modprobe pru_rproc I see only that both PRUs have been probed successfully, but there is no sign of firmware being loaded. My program doesn't work at all so it seems it hasn't been loaded... I have no idea why that could be. I'm coming back to PRU programming after a while, so this might be I'm missing something, but what is this?
My kernel is 4.9.36 ti rt Dmesg output: [ 361.101046] pru-rproc 4a338000.pru1: pru_rproc_remove: removing rproc 4a338000.pru1 [ 361.113437] remoteproc remoteproc2: releasing 4a338000.pru1 [ 361.113740] pru-rproc 4a334000.pru0: pru_rproc_remove: removing rproc 4a334000.pru0 [ 361.114703] remoteproc remoteproc1: releasing 4a334000.pru0 [ 365.601110] remoteproc remoteproc1: 4a334000.pru0 is available [ 365.601329] pru-rproc 4a334000.pru0: PRU rproc node /ocp/pruss_soc_bus@4a326000/pruss@4a300000/pru@4a334000 probed successfully [ 365.608375] remoteproc remoteproc2: 4a338000.pru1 is available [ 365.608639] pru-rproc 4a338000.pru1: PRU rproc node /ocp/pruss_soc_bus@4a326000/pruss@4a300000/pru@4a338000 probed successfully My uEnv file in /boot: uname_r=4.9.36-ti-rt-r45 uuid=0e71d59c-6852-49b0-92b3-1769eaed1c2e dtb=am335x-boneblack-emmc-overlay.dtb Best regards Igor -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
