Mesa 7i92 MAC no longer retrievable

That LinuxCNC message simply means there is no communication.

When you try to ping the card, what error do you get?

Can you access the card at 192.168.1.121?
(move jumper, cycle power, setup host IP)

If so, try running:

mesaflash --device 7i92 --addr 192.168.1.121 --verbose

and posting the results here

When I ping I get Host cannot be reached.
When I unplug the cable I get connection lost and when I plug it in again I get the connection restored from linux.

I have to go to the machine on Monday as it is far from me. I did remote support. I will try the 121 address when I get there.

P.S. We have a number of 7i92's that did the same. We just left them as dead but I would like to get to the bottom of this so we can recover the other cards as well.

Its an odd problem, it may be that there was a bad batch of EEPROMs
that "forgot" their data over time (this is very hard to test for even for the chip manufacturers)

If the card is accessible at 192.168.1.121 and the EEPROM IP address
has changed, this would confirm this theory.

Ok I will test that on Monday and report back.

I tried both the eeprom address and the default address. Neither work. I cannot seem to communicate with the board at all. Not even with mesaflash. I get 7i92 No Board Found error

Do you get link lights on the RJ45 connector?

I would contact Mesa and get a RMA# for any failed cards
so they can be analysed/repaired/replaced.
