Dear All,
About the memory I just changed the dimm to address A0 and now coreboot is reporting correctly 1 dimm detected.

But still no luck on the 0x71 post code loop (looks it is in some kind of loop because is still responsive to power and reset buttons).
I don't know where this loop could be located (coreboot or FSP).
The description on the post_codes.h file shows the following:
....
/**
* \brief Initializing Chips
*
* Boot State Machine: bs_dev_init_chips()
*/
#define POST_BS_DEV_INIT_CHIPS               0x71
....

Any advice on this issue?
Attached is the serial dump with extra information.

Thank you
Jose Trujillo

Dear coreboot engineers:

Right now I am stuck with a Kabylake system with the following message:

May be some configuration is missing and I am trying to find this out myself but if someone of you can give a hint on how to resolve it I will be grateful.

Attached is the full serial dump.

Thank you,
