Generic Serial Flash Interface avalon wait request doesn't negate on 4-byte Quad SPI flash writes.

Hi ALMSlinger,

Are you referring to this document?

https://www.intel.com/content/www/us/en/docs/programmable/683419/21-2-20-1-1/program-flash.html

It seems that you are able to read but not able to write. Can test out any other method of write which can help to identify the problem.

Thanks.

I responded to your question. You haven't answered.

Hi ALMSlinger,

Sorry that I misunderstood your previous respond.

I was thinking is it only a write and not read issue if you can run the Read from memory flash ?

https://www.intel.com/content/www/us/en/docs/programmable/683419/21-2-20-1-1/read-memory-from-the-flash.html

Can try to perform write enable operation for the flash first before a write operation.

Can share if there is any errors info logs.

Thanks.

Hello Aik,

You can close this case. I found a better example accidentally... feel lucky. https://www.intel.com/content/www/us/en/design-example/714766/arria-10-intel-fpga-remote-system-update-via-pci-express.html

Thank you.
Best regards,

Hi ALMSlinger,

Glad that the issue has been resolved on your side.

May I know the what may be the root casue for this issue?

Anyway I will close this thread soon.

Thanks.

Actually, the problem has not been resolved. To be honest, it is most frustrating to deal with Intel FPGA tools... the documentation is so scattered all over the place and in this particular case, the scripts in system console just don't work. I moved to another reference design that I just happened to stumble upon on Intel's website. My hope is that the driver code that comes with the reference design will help me move further along.

Thanks for the interest.

Hi ALMSlinger,

Sorry for the inconvenience. I will take note on your feedback.

At the mean time, I will close this thread for now. Do consider open a thread if there is further question.

Thanks.
