Cyclone 10 GX Development Kit factory recovery issue

Hi,

The dev kit board was working. I could program C10 GX successfully. C10 GX was able to be auto detected with Quartus Programmer tool. See the attached screenshot "auto_detect_success.png".

I was testing C10 GX ASx4 configuration from EPCQ Flash. After a test which possibly erased CFI flash attached to MAX10, (EPCQ flash was also erased intentionally for the test), then I am not able to program C10 GX anymore. Quartus Programmer tool can not auto detect C10 GX. Only MAX10 is auto detected. CFI flash attached to MAX10 is also not shown (which was shown before having the issue). See the screenshot "auto_detect_fail.png".

Then I am trying to perform factory recovery and come to the issue I reported on this thread.

You can also find some details on the other thread I posted earlier "Quartus Programmer fails to auto detect device on Cyclone10 GX Dev kit" at the link below:
