Hello!
We have a Board 5i25+7i77. Our problem is that not determined by the analog outputs on the card 7i77. The external voltage to TB2 is connected. Jumper W1 to the left. The voltage is 5V included from the Board 5i25. Jumper W5 on the left. LEDs CR1, CR3, CR6, CR7 light yellow. CR16 - red. R17 - don't shine. Pncconf start from the terminal. Open loop test shows the error. In a terminal:
Pin hm2_5i25.0.7i77.0.1 analogena does not exist
RTAPI: ERROR: culd not open shared memory (errno=2).
Please, help!

Looks like you do not have communication between with the 5I25 and 7I77
this could be a FPGA configuration issue (wrong firmware), a cable issue or
something else.

Can you open a terminal, and do this:

sudo dmesg -c
linuxcnc
(select a 5i25/7i77 config from chooser)
dmesg > linuxcnc,txt

and then post linuxcnc.txt here

Looks like 5I25 was found and has the correct firmware, but neither serial remote device on the 7I77 was found. If the 7I77 power is on and OK it sounds like either a cable problem, a jumpering problem (both 7I77 setup/operate jumpers (W4 and W12) should be in operate mode (left)) or something weird like wrong PCI clock frequency.

Thank you, PCW!
Now I'm not at work. Tomorrow check the PCI clock frequency. May be the cause of a fault of the Board 7i77?

I would check the jumpers first (and cycle the power if you change them)
That's a more likely problem. It would be a pretty strange PC to have a non-33.XX MHz PCI clock

If the PCI clock is wrong, the baud rates will be wrong so communication with the 7I77 will fail (the 7I77 analog and digital I/O will not be found)

If (and only if) this is the problem it would be best to update to the latest 5I25 firmware that uses the 50 MHZ oscillator (x2 =100 MHz) for the sserial base clock instead of the PCI clock.

We have checked the firmware 5i25. The file is attached. Firmware we took here: mesanet.com

That firmware should be fine. I will verify the same version with LinuxCNC today but I doubt there is any issue with the firmware.
Did you verify that the 7I77 setup/operate jumpers were in the operate positions?

Yes, we have checked the jumpers and the supply voltage. It's all right. Also check the cable again. We see only the encoder. Do not see the analog outputs. Thank you for your help.

I verified that the distribution 7i77x2 bitfile with sserial version 38
(MD5 (7i77x2.bit) = add18c02ff97fcd25805dc15872b460c)
Works fine with either linuxcnc 2.5.1 or master. (2.6pre)
so whatever problem you are having, its not likely to be firmware related

Just in case you have a funny PCI clock you can try the latest 5I25/7i77x2 firmware
freeby..mesanet.com/7i77x2.bit

This firmware uses the on card 50 MHz oscillator multiplied to 100 MHz
for the sserial processor and baud rate clocks so is not dependent on the PCI clock

If this does not work, there must be a hardware problem of some kind so we will probably
have to issue a RMA and have the card set repaired/replaced
