Hi, I had trouble shrinking the pic to send. Anyways-
Spi seems to have never been flashed nor working... my memory fooled me there so sorry for that. I rebuilt the lpt to p4 cable as i had that wrong as well....
But now... still no respone from Mesaflash version x.11 (within lnxcnc img 2.9.4). With jumper w3 i can seemingly select two configs under halrun so both eeprom seeem good.
Both are working under loadrt in epp.mode but none with Mesaflash.
For that i used sudo mesaflash --device 7i90hd --epp --addr 0x378 --verbose --readhdmi
I also tried --addr 0x778
I did try --addr_hi w/o anything added as not sure how to use it...with --addr
I tried many comies - nothing but No 7i90hd found.
Or syntax errors...

I will post the response from loadrt later as it provided some interesting response reharding the interface - matching the comand line in mesaflash but having some more info - cant recall right.now ...)

The lp0 port is confirmed in the boot log ... epp 378 int 5 etc.

under halmon i check some io's and they are updated in linuxcnc. When i short inputs it is visible. at least it seems to work on that side...
Messig about i also get the watchdog bite.
So whats left that im doing wrong :-)

Thanks so far..
At least im a bit more ahead now what to do and check when going for spi... may be... as id like to have it on a pi5...

I would try using the latest mesaflash:

github.com/LinuxCNC/mesaflash

As there were some bugs with the 7I90 name

( build instructions on bottom of page )

I did that as well (think it ended with version .12 2-3 days ago) not sure. But not on both machine and at that point not systematic as there was no difference. But now I will do that again with the current setup... and epp...
I'll update... have a nice weekend...8)

Hello, with the update and after doing a sudo install mesaflash the board is found and its working...
Also mesaflash is now reporting 3.5.16...

So I guess I was too sloppy with my version I build and what I was actually using...

Sorry for bothering you with these basics... and thanks for the responsive help.
Saved me from swapping EEproms...
