Need help writing flex spi nor config for S25FL128LAGMFM010 on i.MX RT1170

[sanjana291]

Hello,

I am working with an i.MX RT1170 and external NOR flash S25FL128LAGMFM010.

I generated an fcb.bin using the MCUXpresso Secure Provisioning Tool, and this binary works perfectly with my board. However, when I use the flexspi_nor_config.c inside MCUXpresso IDE (generated/modified manually), I face issues during debug and get the error please find the attachment for error.  

It seems that the .c configuration I made in MCUXpresso does not match the working fcb.bin.

I need support on:

How to correctly write or align flexspi_nor_config.c with the parameters of my working fcb.bin?

Is there a way to convert the fcb.bin into flexspi_nor_config.c for direct use in projects?

Are there any reference files for flexspi_nor_config.c specific to the S25FL128LAGMFM010?

Any guidance or example configurations would be greatly appreciated.

Thanks in advance!

I think qspiflash_config (in flexspi_nor_config.c file  ) need modify based on  fcb.bin generated by MCUXpresso Secure Provisioning Tool.

Please try to modify qspiflash_config based on fcb.bin, especially pay attention about lookupTable configuration.

We can see the first 4 bytes are ascii "FCFB"   in  fcb.bin.  You can observe the correspondence between the bin file and the qspiflash_config .

Wish it helps you.
