I recently got a Cmod S6 and was able to program it just fine. Now I want to access the Quad SPI so I can load my program directly from the SPI rather than using the Digilent Adept program. The Cmod S6 did not show any references to how to program that part. How do you program the PROM?
I'm using Xilinx ISE suite to design, test and program the Cmod S6 board. At this point I am able to configure the Spartan6 FPGA with a bit file over the USB connection (although I have not verified functionality), but I'm having a problem programming the serial PROM. Here is the report I get from the iMPACT tool: INFO:iMPACT - Current time: 5 Jul 2018 14:00:55 // *** BATCH CMD : Program -p 1 -dataWidth 1 -spionly -e -v -loadfpga PROGRESS_START - Starting Operation. Maximum TCK operating frequency for this device chain: 25000000. Validating chain... Boundary-scan chain validated successfully. '1': IDCODE is 'ffffff' (in hex). '1': ID Check failed. INFO:iMPACT:2488 - The operation did not complete successfully. INFO:iMPACT - SPI Device not found. INFO:iMPACT:2488 - The operation did not complete successfully. INFO:iMPACT - '1': Flash was not programmed successfully. PROGRESS_END - End Operation. Elapsed time = 4 sec. It seems to fail the ID Check, whatever that is. When I selected the PROM device, I chose S25FL128S from the available list. I think that is the correct one. Also, if I try to erase the PROM or do anything else with it, I get a similar error. I tried following instructions posted on this forum, but nothing seems to work.
Hi, I have just received a CMOS S6 evaluation board (410-282P-KIT). Before I program it with my development code I wanted to verify my setup is working Ok. I am using Xilinx 14.7 on a Windows 7 PC. I have loaded iMPACT and successfully initialised the scan chain. I assigned the demo bit file to the FPGA and the demo mcs file to the flash device. When I ask it to iMPACT to verify the contents of the flash memory it fails at address 0. The iMPACT console output is displayed below. INFO:iMPACT - Current time: 11/07/2016 13:18:16 PROGRESS_START - Starting Operation. Maximum TCK operating frequency for this device chain: 25000000. Validating chain... Boundary-scan chain validated successfully. '1': IDCODE is '012018' (in hex). '1': ID Check passed. '1': IDCODE is '012018' (in hex). '1': ID Check passed. '1': Reading device contents... Failed at address, 0 '1': Verification Terminated PROGRESS_END - End Operation. Elapsed time = 1 sec. Is it possible to verify the PROM contents and if so what am I doing wrong? Regards, Stewart.
Hi, I connect the Nexys 3, and when i open the Adept software it doesn't show the PROM option, only the FPGA option which deletes the program every time i power off the Nexys. What should i do for program in the PROM memory? Thanks
