7i96s with 7i76 & sserial device

Hi all.

I'm trying to test and setup my mesa cards for linuxcnc.
My setup:

7i96s (due to chip shortage)
7i76 connected to Mesa 7i96s via 25pin connector
7i73 & 7i84 sserial cards

The problem is: at the moment I don't see the 7i76 card. I flashed the bitfile (7i96s_7i76d) to the Mesa 7i96s. Maybe this is not the correct bitfile?
The 7i96s side is working via linuxcnc, I get connection, the card also detects my sserial device (7i73). But nothing happens with the 7i76.

I don't even know if the combo (7i96s+7i76) is possible to run? Maybe someone has done this before and give me a hint.

Thanks and cheers,
David

Thanks for the help. Yes I did powercycle the board after upload (multiple times).
Below is the readhmid response:

Not sure if the 7i76 is visible. Don't think so..

That's the correct firmware.

Does the 7I76 have both 5V and field power? (both Yellow LEDS illuminated)

Good to know that the firmware is correct. So the issue is on my side somewhere... Yes both 5V and field power are connected but the second LED is not illuminated. I might have a damaged PSU. I will check on that.

Cheers,
David

So I replaced the power supply. It was bad. Both LEDs are now on on the 7i76 but still nothing visible in the HAL.There is the 7i96s and the 7i73 available in HAL.
Next thing to do: checking the ribbon cable.
Any other suggestions?

Is it possible (in theory) to use the 7i76 sserial port to connect another smartserial device? So one sserial device at the 7i96s and one at the 7i76?

 

 

Yes, you have one sserial expansion channel on the 7I96s, and one on the 7I76, and both are usable.

Here is a list of pins from test run of a 7I96S with 7i96s_7i76d.bin firmware and attached 7I76:

 

Thanks for the clarification. I replaced the ribbon cable. Now everthing seems to be working. I can now see all the I/Os of both cards.

I can confirm that the sserial device works on both cards (7i76 or 7i96s) no matter where I plug it in...

Thanks again for the help.
These MESA cards together with linuxcnc are just an awesome piece of kit! .
