Hi All,
I installed EDK7.1i on my computer and built a project. but there are always mistakes.
(1): when i download the bitstream to the FPGA board with the iMPACT of ISE 7 it always show a mistake as follows:
ERROR:iMPACT: 583-"1":The idcode read from the device does not match the idcode in the bsdl File.
(2)however, when i ignore the mistake and then go on to implement the programme "TestApp_Memory" which test the two SDRAMs(this programme is produced with the project automatically), they get the wrong results:
sdram1: passed sdram2: failed
but when i compile the programmes with EDK6.3i, all of the two sdrams will pass.
who knows the reason? please help me!
Thank you!
