Programming .jic to S25FL128S FLASH with Cyclone 10 LP device

At first, there was no problem when I downloaded my .jic file to S25FL128S. However, after operating the Flash through "Generic Serial Flash Interface Intel FPGA IP Core" (including writing and read...

I very much doubt there are any 'special characteristics' of that device. I'm pretty confident I'll have used exactly that part before without issue.

Can you read/write to any part of the device from your FPGA? Is it damaged? You suggest it has previously worked as expected...

Cheers,

    Hi Alex，

    Thanks for you reply.

    I checked the issue with another FPGA board.

    1. At first, the jic file can be programmed into the S25FL128S.

    2. Then, I execute sector protect operation on S25FL128S with "Generic Serial Flash Interface Intel FPGA IP Core".

    3. Then, I failed to program the jic file into S25FL128S, which is expected due to the sector protect operation in step 2.

    4. I unprotect the S25FL128S with "Generic Serial Flash Interface Intel FPGA IP Core".

    5. Still, no way to download the jic into S25FL128S.

    I doubt if some register bits of S25FL128S is locked to prevent the programming operation after step3. Do you have any clue?

    Thx so much!
