I use PINN to dual-boot between the 32 bit and 64 bit Raspberry Pi OS. When I boot to the 64 bit version PINN exits and the screen blanks, but then the ACT light repeatedly flashes slowly 7 times. When I boot to the 32 bit version it starts up fine. Is this problem SD card corruption or a different problem?
Update: I re-copied the /boot files and it boots, but now my mouse and keyboard don't work. What's wrong now?
