flash memory issue

Hello everyone,

I have a Altera max10

I have a flash memory issue. When I download a program in FPGA, then I power off then power on. The program isn't keep in memory.

I use the same software, but with a kit max10. The memory works. So that's mean I have a hardware issue. But when I check some pins like

-CONF_DONE. It has a pull up, so no problem.

-nSTATUS should be connect to a pull up. But it's put in a ground. But normally no impact.

So Except CONF_DONE nSTATUS nConfig. What else pins should I verify?

Thanks a lot
