Mesa 7i77 not working after switching 7i96 to 7i96s

Hello, I'm pretty new to this whole LinuxCNC thing so please be patient if I don't know a lot.
After my 7i96 broke, I replaced it with a 7i96s due to supply. I then updated mesaflash and linuxcnc from 2.8.3 to 2.8.4 and quickly threw together a configuration with pncconf to check if the card was detected. Until then everything seemed fine, but after connecting the 7i77, none of the doughtercard pins like hm2_7i69s.0.7i77.0.0.input-XX were found. Also CR16 is on permanently.
So to make it short, even though everything is connected like before, nothing seems to recognize the 7i77. Can someone tell me where to look for errors? I'm out of ideas.
Thanks a lot in advance,
Mark

Does the 7I77 have 5V power?

What happened to the 7I96?, it is possible the 7I77 was damaged
at the same time?

I can try that board combination later today to verify that there are no
firmware issues

I switched out the 7i77 as well, sorry I forgot to mention that.

7I77 W4 and W12 in left hand position?

Also what is the LinuxCNC startup printout?

(Best done by starting LinuxCNC in a terminal window)

Edit: Tested 7I96S+7I77 with 7i96s_7i77d.bit firmware and it works correctly
so the problem is likely specific to your setup. Could be a bad card or cable
or some kind of more global issue.

Thanks a lot for testing the setup!
W4 and W12 are in left hand position. After starting Linuxcnc from terminal, I get the following (I don't know if you meant this with startup printout, I'm really new to Linux):

It appears that the 7I96S has stock firmware loaded, not firmware to support a 7I77.

To install 7I77 compatible firmware. you would run these mesaflash commands:

mesaflash --device 7i96s --addr[the 7i96s ip address] --write 7i96s_7i77d.bin
mesaflash --device 7i96s --addr[the 7i96s ip address] --reload

The last command can be skipped by power cycling the 7I96S which does a reload

The first command assumes that you are running mesaflash from a directory that
contains the 7I96S configuration files.
