Differential encoder hard crashes the PC MESA7i77

Yes, you need to install firmware that matches the 7I77

You first need to download the 5i25.zip from

  www.mesanet.com/software/parallel/5i25.zip

unzip and then change to the configs/hostmot2 directory and then

sudo mesaflash --device 5i25 --write 5i25_7i77x2.bit --reload


 

still cant seem to find the board 

kind of weird that i can see it talking to a 5i25 in the error file

Did you try running mesaflash after running LinuxCNC?
 

yes, mesaflash still says 5i25 not found

 

Can you do a

lspci -vv  | grep -A 10 2718 > pci.txt

and post pci,txt here?
