Hi


Because the serial flash is also used to store the FPGA bit stream configuration, that is why you would need the offset.

In general you set the offset to be greater than the FPGA Bit stream (SOF).

First you compile your project and you will get a sof file. Check the size and set the offset to be greater than that size. e.g if the SOF file is around 8KByte(0x7A1 200), you can set the offset to be 0x7B0 000

Hi

Thank you for your concern.

E.g if the SOF file is around 801KByte(0x2FBE 4A40),just like image, I can set Hex file around 0x2FBF 0000,but it exceeds memory capacity,the Hex data is around 171KB.

Maybe the way of calculating offset is wrong,or something else is wrong,how to slove the question.

I still want to mention Nios II Flash programmer,can I use it to program cyclone 10 lp device?

Thank you once again.

Regards
