I'm not expert in MinnowBoard Turbot, but I play recently with E3826
and saw similar behavior when incorrect microcode was used (or no
microcode). What are your ucode configuration ?

coreboot support for Minnowboard Turbot E3845

[Michael Graichen]

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
