FPGA doesn't run after pof file programming.

[EEren]

The chip - MAX10M50SAE144. When I program sof file - it runs OK. When I program pof file - it doesn't run.

nCONFIG - pull-up, CONFIG_SEL - pull-down, CONFIG_DONE - pull-up.

What could be a problem?

Hello,

Do you have scope shot for below signals:

1. nCONFIG
2. nSTATUS
3. CONF_DONE
4. VCC, VCCA, VCCIO

How did you generate the .pof? Can you make sure the Quartus version is same?

regards,

Farabi

Thank you. The problem was a missing pull-up on nSTATUS.
