Hi,
I'm trying to follow http://processors.wiki.ti.com/index.php/RPMsg_Quick_Start_Guide to set all 4 PRU cores to work with RPMsg.
After I and reboot my device, I can only see PRUSS0_PRU0 and PRUSS0_PRU1's virtio port in /dev (rpmsg_pru30 & rpmsg_pru31)
I found that there are different information between unbinding/binding PRUSS0_PRU0 and PRUSS1_PRU0:
unbind/bind PRUSS0_PRU0:

It looks like that PRUSS1_PRU0 didn't load any firmware, but I can't find out which part I did wrong.
Please help me, thanks!
Best Regards,
Leif
