I'm using an Atlys board and I've succeeded in programming some of the demo projects (like the GPIO and UART demo project DSD-0000327).
But when I tried to program the VmodCAM project DSD-0000309 or DSD-0000310 using Xilinx iMPACT, it said "Program Failed" when the progress bar went to about 4%, and then the board rebooted.
The following was displayed in the iMPACT console:
PROGRESS_START - Starting Operation.
Maximum TCK operating frequency for this device chain: 0.
Boundary-scan chain validated successfully.
'1': Programming device...
LCK_cycle = NoWait.
LCK cycle: NoWait
'1': Reading status register contents...
INFO:iMPACT:2219 - Status register values:
INFO:iMPACT - 0000 0000 0000 0000
PROGRESS_END - End Operation.
Elapsed time = 5 sec.
I've tried the bit files provided by Digilent and those generated by myself (in ISE 14.7) from the source files. Neither of them worked. (The demo project was built in ISE 13.2, tested in ISE 13.1, according to Digilent's comment. But I think it should work in ISE 14.7 as well. I updated the IP cores used in the project anyway)
Then I programmed the flash with the bit file using Xilinx Adept, but the board fell into endless reboot loop...
I don't know why this demo project can not be downloaded... Any help would be appreciated :-)
