LPC55S69 Secondary Bootloader Reinvoke

[henninjw1]

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.
