Requesting you to resolve the programming on Cyclone V SX SoC Development Kit

Board: Cyclone V SX SoC Development Kit
FPGA: 5CSXFC6D6F31
Quartus: Prime Lite 20.1 (Windows 11)
JTAG Cable: USB-Blaster II
Observed JTAG devices:
  SOCVHPS
  5M1270ZF324
Expected device missing: 5CSXFC6D6F31
SW4 set to FPGA-only, SW2 all OFF, power-cycled
Conclusion: FPGA JTAG appears isolated / held in reset by board controller

    Hi,

    sounds like you got SW4 settings wrong. Which devices are recognized in default JTAG setting, SW4 = off, off, on, off, JP6+7 installed? FPGA only should be SW4=on, off, on, on.

      thank you for the response,

       I have checked for SW4 = off, off, on, off.it is showing the 5M1270, SOCVHPS and if I click auto detect, it is asking for select the device, I have selected(5CSXFC6D6) and confirm it. I have checked the JP6+JP7.

      after that,               

      I have done this, FPGA only should be SW4=on, off, on, on. I clicked on the auto detect, then it is showing this below error,

      unable to scan device chain. can't scan JTAG chain.do you want to open the JTAG chain debugger to troubleshoot the JTAG chain?

       

      can you please tell me what I have to do further.

       

      Best regards,

      Bachan

        Hi Bachan,

        my answer was based on user manual and schematic. Unfortunately I don't have the board and can't help further. Altera support should take care for the problem.

        Regards Frank
