BTW we have a tool for creating board-2.bin so that you don't need to
use hexedit:

Unfortunately no documentation but hopefully --help provides some guidance.

Can you report this to bugzilla.kernel.org:

https://wireless.wiki.kernel.org/en/users/drivers/ath11k/bugreport

That way it's easier to track. I'll try to find a board file for this
device.
