Hey Zoran,

thanks for your help!

Is there some place to look up the connection between CPUID and microcode?

I tested M0130679905.inc but still with the same effect.

So I flashed the original Image and booted Linux.
/proc/cpuinfo tells me that the original image is using microcode: 0x906

but where can I find it?

Best Regards

Michael

This is CPUID 0x30679, which uses MCU M0130679901.h (ONLY this one).

You can also try the following MCU: M0130679905.inc (attached). You need to convert it to .h

Hey Piotr,

I'm glad to read that somebody else is working on the Atoms as well.
I'm not sure about my ucode config. At the moment I'm using 5 include files:

M0130673322.h
M0130678806.h
M0130678817.h
M0130679901.h and
M0230672228.h

for a E3845 Family: 0x06 Model:0x37 Stepping: 0x09.
I copied the includes from various FSP's and the FSP_GOLD packages.

I tried other combinations before but then i had no output on the serial
line so I ended up using these five.

What is your Familly/Model/Stepping and what are you using for ucode?

Best Regards

Michael
