First try at setting up a Mesa card as well as a newby to Linuxcnc. Oops!
I mistakenly flashed my 7c81 with 7c81epp.bit ,( thinking it would be the best match to my existing Mach3 parallel port)
Now my board responds like this and I don't know how to get it back
sudo mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --readhmid
unable to set bpw32, fallback to bpw8
Unexpected cookie at 0100..0110:
00000000 00000000 00000000
No 7C81 board found
Here is the complete mess I've made, can some kind soul help me put the genie back in the bottle?
