From the microchip documentation I gathered that there are 4 Boot Mode options:
Boot Mode 0 (Idle Boot): Code is not executed on power-up
Boot Mode 1 (Non-Secure Boot): Boot directly from eNVM (alternatively from any FPGA fabric memory resource)
Boot Mode 2 (User Secure Boot): User defined, PUF-protected secure boot
Boot Mode 3 (Factory Secure Boot): Microchip secure boot
I am guessing the BeagleV-Fire uses Boot Mode 1 (if no reconfiguration is done), but I am struggeling to confirm or check this.
What boot mode does the BealgeV-Fire use out of the box, and is there a way to confirm it?
