xilinx idcode wrong
Hi Group
I have developed my own Xilinx SPARTAN3-400 board but have a problem when trying to connected via JTAG to the FPGA, i am using the USB Cable from Xilinx but with out luck.
There is only one FPGA in the chain, i have rechecked power sequencing, and recehecked the connection to the FPGA JTAG/POWER/Ect.
The ID code i can read from the spartan via Chain debug in Impact:
00000000000001111000011110111111
I have tested when a eval board from memec with the same FPGA which returns:
00000001010000011100000010010011
I really dont have any ideas more whould could be the problem, are there
somebody how can give me a hint to would me could be te problem ?
Thanks a lot in advance
Best regards
René
