i got a problem with the Spartan 3E starter kit from Xilinx, no matter
what Mode pins are set for, the DONE LED is always turned on when i
power on the board. I cannot connect to the board via JTAG pin headers
either. All the voltages are correct. What could be the problem ? any
thing i can do to debug it ? i have another Spartan 3E board and it
works fine.

the LED is on even though i hold PROG_B low

Check shorts.
Check power voltages.
Check the schematics.

when measured all the signals are grounded, including the unconnected
jtag signals (which should be pulled high from internal pull ups) ..
can the FPGA be damaged somehow ?
