Hi,

Sorry to bother you all, but has anyone here ever used the trenz-electronics XC2S spartan board? I bought it about a year ago and just recently started working on it. I tried earlier to program the flash rom from which the spartan will then load automatically. Whenever I start the webpack4.1 impact programmer, I keep getting an error telling me to set the JTAG clock setting. I've done it, but I can't get the stupid thing to properly initialize and program itself. Well, I've gotten this thing to work before. What gives?

Thanks,

I think this is a trouble with the board. I don't know trenz-electronics boards and schematics.

Could you let me know how the CE# of the FLASH is connected.

Normally, we have to add electronic or just a jumper, to allow

1) a connection between the done signal to the CE# in normal use (FPGA in master serial or parallel) 2) a disconnection of the done signal and the CE# in JTAG mode and auto-configuration using CF pin of FLASH to generate a pulse on FPGA program pin

Loi,

What is the exact error? Is it about Startup clock? If yes, set the startup clock to CCLK, and make a proper mcs file. Then read the manual, and set the M0-M2 Jumpers to boot from flash.

If you can't fix this, contact me directly at t.trent at trenz-electronic dot de

best regards Thorsten Trenz
