Can't write to FLEXSPI on project evkmimxrt1170_mcuboot_opensource

[kayakaantuna]

Hi,

I was trying the OTA function for rt1172. However, in this line:

boot_set_remap_flag(FLASH_AREA_IMAGE_PRIMARY(0));

even though it returns kStatus_Succeess when I read it back I can't see the change at the address 0xfffe0.

It seems that it is a configuration issue, on FLEXSPI side. I did, include customLUT and linkerscripts, but problem still stays.

Appreciate any help possible

Hi @kayakaantuna ,

Actually I didn't find the line of "boot_set_remap_flag(FLASH_AREA_IMAGE_PRIMARY(0));" in the project of evkmimxrt1170_mcuboot_opensource, is it from some custom code? Please kindly clarify.

Have a great day,
Kan

Sorry for very late response.

I found the solution and here is what you need to do, very shortly:

-Use the github link I gave below and get required files. You need to enable SOC_REMAP_ENABLE. So you basically need to boot_remap_go function functional, since the example evkmimxrt1170_mcuboot_opensource doesn't include those files.
https://github.com/nxp-mcuxpresso/sbl

-Once you have compiled the code successfully with no errors, you need to modify flexspi functions that are used on evkmimxrt1170_mcuboot_opensource example, because they are simply don't work (atleast for me). Import sdk flexspi example of your choose and copy the functions that are used on that example and include them into your mcuboot_opensource project.

And after that your sbl will work like a charm!
