You might try explicitly setting the high address in the hm2_7i43 command line (and the debug option)

did you try the --readhmid mesaflash option?

What kind of parallel port card do you have (what chip manufacturer?)

what does lspci report for the parallel port addresses? (trying to verify the high address)

Thank you for the support.

lspci:
Warning: Spoiler!


It is a Sunix 4008T card. I have a Sunix PAR6408A card for pci-e, but cant use it.
Tried also "cat /proc/ioports":

Ok. Everytime I use only the terminal I can get a connection to the 7i43.

Once I try to start linuxcnc I get an error. After that the pc freezes when I try to reacg for the card by the terminal.

You would need the

lspci -vv

option to show addresses

Ok. that is new:

cnc@linuxcnc:~$ sudo mesaflash --epp --device 7i43 --addr 0xd000
[sudo] Passwort für cnc:

EPP device 7I43 at 0xD000:0xD400

I can get some strange results:
loadrt hm2_7i43 ioaddr=0xd000 ioaddr_hi=0xd400 epp_wide=0 config="firmware=hm2/7i43-2/SVST4_4.BIT

Gives me:
No parport registered at 0xd000. This is not always an error. Continuing.
hm2/hm2_7i43.0: invalid cookie, got 0x00000000, expected 0x55AACAFE
hm2/hm2_7i43.0: FPGA failed to initialize, or unexpected firmware?
hm2_7i43.0: board at (ioaddr=0xD000, ioaddr_hi=0xD400, epp_wide OFF) not found!
hm2_7i43: rtapi_app_main: Invalid argument (-22)

If I change to:
loadrt hm2_7i43 ioaddr=0xd010 ioaddr_hi=0xd410 epp_wide=0 config="firmware=hm2/7i43-2/SVST4_4.BIT

I have to change to the 7i43-4 firmware because linuxcnc said thats tghe wrong one. Wit 000 and 400 it is vise versa...

0xd400 cannot be a valid address as its not listed by lspci

that is,  "ioaddr_hi=0xd010" should be tested

Also hm2/7i43-2/SVST4_4.BIT is a bitfile for a 7I43-2, but you have a 7I43-4
