Hi crim_,
I have a HP Pavilion 570-p014 with Willow2 Motherboard.
Did you upgrade one of Willow or Willow2 with a Ryzen APU?
Did you also face any issues?
Thanks in advance. There is very little information out there. I checked the BIOS update history for Willow2. The 'fixes' sections don't mention "Ryzen" or anything processor upgrade related.
