Hi Anand, thanks for your help.

I checked "Enable real-time ISP to allow background programming when available" in Quartus programmer. At first, the programmer gave me an error:

Warning (16328): The real-time ISP option for Max 10 is selected. Ensure all Max 10 devices being programmed are in user mode when requesting this programming option

Error (209012): Operation failed

I downloaded the SOF file through JTAG then it proceeded to program and verify the new flash without any errors. It seems to me the JTAG download forced it to user mode. But after I power cycled the 10M25 device, it didn't get configured from the flash.

Arrow Electronics, one of Intel's partners has a visit to my company w.r.t. this issue on Wednesday. I will see what they say.

Best regards, SV.
