I have requested FSP MR2 but yet to receive it.

But I checked the FSP file included in Apollo_Lake_CB_MR3 release and it has the same cksum with the FSP MR3 I have.

And this Apollo_Lake_CB_MR3 pre-compiled coreboot image is bootable on my CRB! :( Confusing...

Anyway, good to know that your FSP MR2 is working.

I think will just wait for the MR2 and check again.

BTW, I notice this in your config:-

CONFIG_CPU_UCODE_BINARIES="blobs/microcode_patch_1.bin"

I didn't set this in my previous configuration.

Is this from FIT tool?

I noticed there are 2 files after decomposing with FIT tool, "uCode Patch 1.bin" & "uCode Patch 2.bin"

But you only need 1 file here?

Thank you.
