Modify imxrt1024 SDK flashloader example to run on flash

rodrigocsm — Tue, 11 Apr 2023 20:23:26 GMT

Hi, I'm new to imxRT processors and I'm trying to develop a secondary bootloader for the imxrt1024. At first I'm using the flashloader example from SDK as a base. What are the steps to modify the project, from RAM to Flash?

Hi @rodrigocsm ,

RT1024 support the ROM API, you can use the ROM API, that code can run in the flash directly.

Please check this SDK code:

SDK_2_13_0_MIMXRT1024-EVK\boards\evkmimxrt1024\driver_examples\fsl_romapi

Wish it helps you!

Best Regards,

Kerry

Thanks @kerryzhou. I'll try.

Just a question. There's no ROM_RunBootloader function in the fsl_romapi. Can I implement it manually or it doesn't work on imxrt1024?

Hi @rodrigocsm ,

Do you check the evkmimxrt1024_fsl_romapi project which I recommend you?

In fact, that project is using the ROM API to realize the flash operation. So, you can add it in your secondary bootloader.

BTW, we also have the SBL for your reference:

Wish it helps you!
