Unable to run the application with image header using custom bootloader in IMX RT1170

[Ragnar]

Hi NXP,

          I'm trying to develop a custom bootloader for my board and when I try to jump to the application. I was unable to reconfigure the device from the application using image_header.

1. When it try to run the application without image_header. I was able to jump to the application and run it with the existing bootloader device configuration. But it is only limited and if I load the different bin file other than existing with different configurations it is getting failed.

2.When I try to run the application with the image_header. It is jumping but stucking at the start itself.

I am using RT1170EVK 

My boot loader starts at 0x30000000 and ends at 0x30010000

Application starts from 0x30010000 ends at 0x31000000

So, can you please help me with this problem.

Regards,

Ragnar.

Hello @Ragnar ,

In order to support you better can you provide me the next information?

-where will be loaded your image? (RAM or FLASH)

-Is the image_header the header of the IVT?

-Are you using Serial downloader or internal boot?

Hi @Habib_MS , 

           Thanks for the response. I found that the problem is with my flash loading function as it's not erasing some sectors as a result it is overwriting to the existing data. So the flash data is getting corrupted and I was unable to run the application. Now it got resolved and thank for providing the reference it helped me a lot.

Regards,

Ragnar.
