Thanks to much help, I have a dts/dtbo loaded, and my firmware setup via /boot/uEnv.txt. After boo, everything seems fine, and the remoteproc firmware points to my firmware. Everything is how I want, other than the state is offline. If I think just copy “start” to the state file, they are off an running. Is there a way I can have them start running via the uEnv.txt or dts? If so, how?
