FPGA not configured from flash EPCQ128A with generated .rbf file issue

FPGA is regularly configured with .jic file. .jic and .rbf are generated from the same .sof, with Quartus Prime Standard Edition, Version 18.1.0 .jic and .rbf file generated with parameters: Con...

Hi Dragan,

Just would like to check, have you program SOF and JIC into the device before? Is it working fine?

Regards,

YL

Hello,

FPGA is never configured from FPGA flash EPCQ128A with RBF which is generated by Quartus 18.1.0.

FPGA is always configured from FPGA flash EPCQ128A with JIC which is generated by Quartus 18.1.0.

Old FPGA flash EPCQ128N (Quartus 15.0.0 was used):

JIC (via JTAG) and RBF (via TFTP SW update) are successfully flashed on FPGA flash EPCQ128N and FPGA is configured after reboot device in both cases. Those JIC and RBF were generated by Quartus 15.0.0 from same SOF.

New FPGA flash EPCQ128A (Quartus 18.1.0 is used):

Now, we are using new FPGA flash EPCQ128A. For new FPGA flash (EPCQ128A) JIC and RBF are generated by Quartus 18.1.0 and state is:

  • JIC is flashed (via JTAG) on FPGA flash EPCQ128A and after reboot device, FPGA is successfully configured
  • RBF is flashed (via TFTP SW update) on FPGA flash EPCQ128A, but after reboot device, FPGA is not configured

Files JIC and RBF are generated from same SOF.

Dragan
