Necessary firmware for Navi14
power9mm:
do i need to worry about placing the jumper for the AST or is blacklisting it in bootloader for the OS all i need to do?
MPC7500:
Jumper or blacklist. Blacklistng has some advantages.

@MPC7500 If you blacklist the AST can you interact with Petitboot?

Yes - if you flash the correct firmware to Skiroot's BOOTKERNFW section. But knowing which subset of the multiple megabytes of modern Radeon firmware to load into the ~1.8MB sector allocated for storing that firmware was why I created this thread back in late July of 2022... and I still don't know the answer there. So now I just toggle inputs between an HDMI to the BMC video and DisplayPort to the Radeon as needed.

Yes. Blacklisting AST is post-Petitboot.
