LPC55S69 Secondary Bootloader Reinvoke

henninjw1 — Wed, 21 Sep 2022 13:30:58 GMT

Hello,

I am running through the example in app note AN12327 using an LPC55S69-EVK. I am able to flash the bootloader and then run the flash_program.bat tool the load the dsbl_app program. The issue I am running into is trying to re-enter the bootloader from the app using the sbl_api as described on page 12 of the app note. When I uncomment the sbl_api->reinvoke(); command in the app I get a hard fault failure. I am using the MCUXpresso example code in the app note.

Thanks.

Hi @henninjw1

I hope you're doing well.

Could you tell us the revision and date code of your chip?

Here is an example of where to find those in your chip.
