Hi,
I am trying out the Arago build for TI AM335x Starter Kit (TMDSSK3358).
I built the image with:
git clone https://git.ti.com/git/arago-project/oe-layersetup.git tisdk
cd tisdk/
./oe-layertool-setup.sh -f
configs/processor-sdk/processor-sdk-kirkstone-09.02.01.09-config.txt
cd build/
. conf/setenv
MACHINE=am335x-evm ARAGO_RT_ENABLE=1 bitbake -k tisdk-base-image
Then I boot the image and try to load the firmware with the following error:
root@am335x-evm:~# dmesg | grep pru
[ 29.717917] remoteproc remoteproc0: 4a334000.pru is available

root@am335x-evm:~# cat /sys/class/remoteproc/remoteproc0/firmware

If I look at the firmware folder:
root@am335x-evm:~# ls /lib/firmware/ti-pruss/
am335x-pru0-prueth-fw.elf am335x-pru0-pruprp-fw.elf am335x-pru1-pruhsr-fw.elf
am335x-pru0-pruhsr-fw.elf am335x-pru1-prueth-fw.elf am335x-pru1-pruprp-fw.elf
I also tried:
echo 'am335x-pru0-prueth-fw' > /sys/class/remoteproc/remoteproc0/firmware
root@am335x-evm:~# echo 'start' > /sys/class/remoteproc/remoteproc0/state
-sh: echo: write error: No such file or directory
[ 458.718686] remoteproc remoteproc0: powering up 4a334000.pru th error -2

Could you please help me on this issue? Thanks in advance!
