Help with mesa 7c81 and 7i77 setup. Possibly corrupted flash

Some good news!

I was able to find the parts to build another cable and it worked! Or at least mesaflash can talk to the card again.

I forgot I had a 90deg adaptor in there because there wasn't enough clearance between the two boards. I redid the spacers to give it more room and a much shorter cable.

Now to reinstall the board in my machine and see if it can talk to the 7i77 and then back to wiring it up. Which is where I expected I'd need help but one problem at a time.

Thank you for the help.

I've reinstalled the board and was able to run --verify with mesaflash against the bit file I had flashed (came back ok)

ran pncconfig (with no real i/o or axis setup since none of the wiring is done yet)
modified the ini and hal files for the 7c81
linuxcnc started up without error and I see both the hm2_7c81 and 7i77 under halconfiguration

Green flashing light on 7i77

Now on to the wiring. If I have trouble I'll probably post under another thread since it's not really related to what went wrong here.
