Hello everyone,
I am also trying to reload AON/SPE firmware without rebooting. Do you know why I am getting this kernel error? I am pretty sure that It is SCR/Firewall issue but without SCR documentation I don’t know how i can reload SPE using DebugFS.
It seems that i have successfully reloaded firmware but i am not able to reboot SPE, and that is why i am getting this error.
