Hi all,I'm struggling with the following Mesa card combination: 7i92 + 7i77 + 7i76.I’m using the firmware
. Unfortunately, only the Smart Serial peripheral on P1 is being detected — nothing shows up on P2.To clarify:
When I flash a different firmware, the same card that previously didn’t communicate on P2 works fine on P1, so I believe the Smart Serial slave and its power supply are OK.Here’s the output of
:
yaml
CopyEdit
I read somewhere that there should be more than one SSerial interface listed if both ports (P1 and P2) are configured for Smart Serial. It seems like the firmware might not be enabling SSerial on both channels.Has anyone encountered this issue?
Or is there someone with a working build environment who could check the Mesa source files to see if there's a configuration error?Any help would be greatly appreciated.@PCW – if you have a moment, your insight would be very welcome.

7i92_7i77_7i76D.bit

One sserial port can have from 1 to 8 channels so the mesaflash information is correct.
If both cards don't show up in hal, its likely that they are not enabled in the sserial_port_0=nnnxxxx
stanza in the driver command line
