EP3C40F484C8 fail to reset properly with .jic file

--- Quote Start ---

Hi,

So we have a EP3C40F484C8 having a LED for the CONFIG_DONE and NSTATUS.

The normal process and working process :

1- flash jic file on flash with quartus programmer

2- reset the fpga.

3- LEDs for CONFIG_DONE and NSTATUS are ON from the moment the reste button is pressed.

4- After some times (seconds) the LED go OFF.

So the current problem we have right now is that the .sof is working but not the .jic file. What is not working is not the programming part but after the reset:

1- flash jic file on flash with quartus programmer

2- reset the fpga.

3- LEDs for CONFIG_DONE and NSTATUS are ON from the moment the reset button is pressed.

4- LEDs stay ON and the code on the fpga is never process (ex: blinked light)

Any ideas on how to debug this?

Best Regards

We discover that our msel[0..3] pins are not properly wired. They are set to 0101 and we should have the last pin msel[3] to zero and not 1.
