I am far from an expert, but:

have you previously run flashrom successfully on this device?  Other
  apu2 boxes?

I have run flashrom under NetBSD on two apu2 boxes.  I did this in
  March with the then-current BIOS, v4.13.0.6, which worked entirely
  fine.  I am 90% sure it was 1.2, but I might have been running 1.1.
  One apu2 was bought in 2019, and I think is a 2d4 and the other in
  2020, I think 2e4 but it might still be 2d4.

I really don't expect 2d4 vs 2e4 to be any different

I hope you ordered the BIOS rescue chip when you got your apu2.  I did
  but I have not needed it.  It's very cool that such a thing exists.
