Hi all experts

I have a problem with NOR flash when it reads and writes.

Here is my parameters

Arria10 (with quartus prime standard edition)

Micron Serial NOR flash 1.8V (MT25QU01GBB

(There is limited images I can post, so I will put the link on reply)

Msel = 010 (hard wired) as below

(There is limited images I can post, so I will put the link on reply)

epcq_controller in qsys was set as below

("STANDARD" & "QUAD" both cases were tried)

devices & pin option was set as below

(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)

If you have any idea or any suggestion, I appreciate your help.
