Hi,
it's not necessarily a defective SFL image. Can be also a JTAG problem or unexpected reconfig happening at the target system.

You didn't report the used Quartus version. I would try to load sfl_enhanced_ep4cgx30cf23.sof and alternatively sfl_ep4cgx30cf23.sof manually and try flash action with disabled sfl programming.

Hi Frank

I could download sof via JTAG into FPGA without any issue. Try to convert JIC with flash loader by both Quartus standard version 18.1.1 & 23.1.1 and get the same error.
