Dear Naresh, I choose the RVP8 board because is the only match in terms of CPU and memory, other templates made by google supports kabylake U/Y only processors and no DDR4.
My system has differences and I will check them after I finish GPIO. I already determined the proper VR settings and set them in devicetree (the default voltage setting was 0V -power was shutdown??-) and I will see if after the corrections of VR and GPIO the system boots. I will follow your advise of checking EC and about the base FW I am using the original UEFI AMI FW but, if still doesn't boot I will replace ME and descriptor as you suggested. Thank you, Jose Trujillo. ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Thursday, September 20, 2018 4:03 PM, Naresh G. Solanki <[email protected]> wrote: > RVP8 is known to boot.
