Hi,
Is it possible to enable more prints or “debug prints” in the PSC / MB1 / MB2 during startup?

I wish to better understand/monitor boot process in general and analyze secure boot, PSC execution for security in particular.

Thanks

Hi BSP_User,

You could just refer to the developer guide for bootflow.
Jetson AGX Orin, Orin NX and Orin Nano Boot Flow — Jetson Linux Developer Guide documentation (nvidia.com)
As I know, the source for these stages is not public so that you could not do further debug.

Thanks. I read it but looked for more informative prints (I asked since its possible in UEFI)

UEFI is open source, and the print is default disabled.
However, MB1/MB2 are both print default enabled.
