(I also tried "AUTO" for "EPCQL1024" & "1.8V" in configuration device) 

 

 

When I tried to write .sof image into flash by using "NIOS II Flash Programmer" 

Error message pops up as below

Do you have any idea or any suggestion for this issue?

To debug this issue, read & write test was performed by using Memory Test template  

 

Here is my result of Memory Test template (below)
