[flashrom] Attempting to flash rom

[Dan Hellerstedt]

I'm trying to flash the rom on an HP Envy 20 (model 20-d034) as oxide
suggests here:
https://h30434.www3.hp.com/t5/Desktop-Video-Display-and-
Touch/HP-Envy-20-Black-Screen-On-Startup/m-p/5715628#M89817

However, I am getting this error when trying to create a backup or read the
rom.

what does it mean when "requested mapping is incompatible"? any suggestion
on what to do next?
