Trenz-electronics (spartan2 development board) help?

[Loi Tran]

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,

LT

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
