Qartus command prompt flashing is unsuccessful throwing "Can't access JTAG chain" error message

We are from XPIV team covering automation for the PM and MSS. We were using the Quartus tool to flash the CPLD and we have the scripts in which the CPLD flashing is automated. While using the quartus...

Hi,


From the error message, it seems like the device part number is not the same between physical device and device selected in quartus. Can you please check on it?


Also, can you try to reduce the TCK frequency of USB Blaster II to 6MHz?


Thank You.


Regards,

Bruce

Ram's Observation

Providing the data here, instead of posting on the community.

We reduced the JTAG programming clock frequency to 6 MHz and tried flashing the CPLD firmware. The issue still persists.

  1. Command to set clock frequency to 6 Mhz: jtagconfig --setparam "USB-BlasterII" JtagClock 6M (Attachment: 6Mhz.PNG)
  2. GUI based CPLD firmware flashing passed, platform booted fine. I saved the associated cdf as “Chain1_6M.cdf” (Attachment: Chain1_6M.cdf.txt)
  3. I then tried flashing the firmware using this CDF file, which failed, with the similar issue as before. (Attachments: CLI_Error.PNG and CLI_Error.txt)

Command that I used to try and flash the firmware: quartus_pgm -c "USB-BlasterII" Chain1_6M.cdf

Please let me know if I might be missing anything here.
