Remora - ethernet NVEM / EC300 / EC500 cnc board

Hi
the board is a 3-axis, but I don't think it depends on that, I think.
Ultimately, on six axes XYB working, Z and C turning in one direction, dir doesn't work, A doesn't work.
I haven't had any luck....
this is the second board, the first one in understanding how to flash it I must have made it unusable, I can't get it back.
I don't want to buy another one, never mind.
Thanks for the feedback

try this: pair the contents in this dir:
github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic
download this:  github.com/scottalford75/Remora-RT1052-c...xCNC/nvem-rt1052.txt pair your files:nvem-rt1052.hal,nvem-rt1052.ini
then: 
and try again please

I try again and C turning in all direction.

Thank you
it's not a configuration problem
I tried the procedure you described, but nothing changes

 

XYB works, ZC dir doesn't work, A doesn't work
it's a hardware problem.
Thanks

can you desoldering and test this? or replacing it shouldn't cost too much.

I guess the culprit is that chip, I already tried to redo the soldering, but it was no use.
I have the first unusable board with two of those chips, I'll see what I can do, I've never unsoldered/soldered chips like that.
thanks
