@westlake is on fire

I have compare b0671 0x123 vs 0x125 and 90672 0x35 vs 0x36, the last 20 KB of the binaries haven’t changed, does anyone know why?

Edit:
i was thinking that both b0671 and 90672 have p-cores and e-cores. maybe the last 20 KB control the e-cores. and no changes were made to them.
guess we will never know …

There is nothing new. The database you’re using is old. I assume it’s from UBU. It has v1.94.2 (r276).

Interestingly, there is a microcode with the same date and version (917DC5C4).

Didn’t check thoroughly, Sorry if it’s an old one?

To my knowledge, there are no other public. At least one that someone has found.

Yeap, correct observation. A big issue with AMD is that microcode blobs don’t have an end user-verifiable checksum or hash. Thus, any corruption can manifest as a new (valid) blob.

@lfb6 Do you remember the source of this particular blob? Maybe bad extraction of the original BIOS image or similar can be identified.

I was able to (re-)find the currently known blob here, for instance:

https://dlcdnets.asus.com/pub/ASUS/mb/BIOS/Pro-WS-TRX50-SAGE-WIFI-ASUS-0701.zip?model=Pro%20WS%20TRX50-SAGE%20WIFI

From LVFS, so there’s much Dell, HP or Lenovo. Traveling now, so not able to look it up, I’m sorry!
