Hi,
I've got a couple of Pluto3-RevA boards (just getting back into fpga's again)..
Using TXDI board to program..

I'd been using one with no problem up until today.. it won't configure..
It loads the default code from the PROM (default blinky led code), but that's all I can get it to do now..

Tonight I've tried one of my other Pluto3-RevA boards and it works fine with the TXDI board, so I've done something to one of my boards..

I poked around on the board with a cro, found the resistor / zener for the serial line and compared good board to bad board.. all seems ok..

I have not tried to jtag program the board, as I don't have a parallel port or a usb jtag programmer at the moment..


Is there anything I can poke at to check?

Regards
Neil Davey

Just an update if anyone is interested...

I got my hands on a Altera USB Blaster... first quick test it looks like it can still be configures via jtag.. no apparent errors, but have not checked fpga operation yet..
