i am using am437x. It has 4 cores, i want to know that: dose the linux sdk supports 4 cores firmwares' loading? Does it means i just define the 4 firmware name, it will auto load it?

Hi, Yude,

Remoteproc during the boot will take care of the downloading if it finds the specific files in /lib/firmware. You can untar the filesystem in Linux ProcSDK. You should see 4 PRU files in /lib/firmware. They are currently symbolically linked to RPMSG echo interrupt example demo. Replace them with your own executables would do.
