7i96s boot problem was created by ioiotutu
Hi,
I have a 7i96s that worked fine for a day and then during a reboot it was no longer recognized by linuxcnc. Looking at the LEDs on the card I noticed that the init, done and power LEDs remain on and I don't have the ethernet link up.
Following the manual I put the w1 and w2 jumpers in the up position, but the board remains with the LEDs on and ethernet link is down!
What can I check?

Sounds like either a power supply issue (marginal 5V)
or corrupted flash (wrong bitfile written, which is possible
with older mesaflash versions)
I guess it could be a failed flash chip, but this is pretty rare.

The card is new one. The power supply is 5.12 V.
I didn't use mesaflash, the standard flash is ok for me.
If the flash is corrupted, Is there a way to try to reprogram the card?

Its possible but requires the Efinity JTAG software and a compatible JTAG interface
Probably best that the card be returned for analysis/repair/replacement.
