Re:5i20 + 7i52s + 7i37TA -> change the IO Pins

Can you show us the file?

Of course. After much trial and error I succeeded in compiling my own bitfile. However with very many warnings (See attachement).
Linuxcnc starts with this bitfile. PWMGEN and STEPGEN also generate correct signals. SSERIAL I could not test yet. I still lack the ICs for the exchange on the 7i52s.

Content of the appendix:
PIN_WEILER160_CNC.bit
PIN_WEILER160_CNC.vhd
readhmid.txt
WARNINGS.txt

That does seem to be a lot of warnings, but they are all warnings rather than errors, so it looks like the compile worked.

Whether the warnings can have an impact on the result can only be answered by the Peter.

Good news. The modification of the 7i52s works fine. The 7i73 connects itself after the start of Linuxcnc and shows standby with blinking green LED. The 2xStep/Dir and 1xPWM/Dir also bring correct signals. After that the conversion of the 7i52s and the self-compiled firmware was a complete success.

Well done, that's a pretty ambitious bit of hacking. (And it's rather cool that the drivers knew what to do)
