Update: The problem was, as I suspected, the MCUXpresso generated project failed to properly initialize the boot header.
To get this project to run, I did the following:
- copied the files evkmimxrt1024_flexspi_nor_config.h/c from a working project (running on EVK),
- defined as 1 the symbols XIP_BOOT_HEADER_ENABLE and XIP_EXTERNAL_FLASH
- Note: no changes to hardware BOOT_MODE pins were required.
Please Note: MCUXpresso bug - failed to properly set up execution from internal flash in generated project.
The complete buggy generated project was attached to the original post above.
I've attached the nor config files below. Can you tell me:
Are the settings in the code below correct for MIMXRT1024CAG4B (different processor from 5B on EVK)?
Thanks!
Best Regards, Dave
