Hello Nico,

Yes, I am using Intel Kabylake DDR4 RVP8 board.

> Never use another board's GPIO settings.
Reading the mail list yesterday I saw that warning maybe from you and I will do the correct changes to GPIO just after editing VR settings.

I am just started coreboot several months ago and there is still a lot of road to go for me and still don't understand many things; but I am doing my best to get aligned with the coreboot project.

After the GPIO changes I will check my schematics to check for hardware differences before I flash it into my device.

Thank you ALL for your help.
Jose Trujillo
