Hi @jnj ,

   Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.

   After you: flash boot loader ,bootstrap and application binaries using Ivaldi tool and serial down loader method

 Whether the code function works or not after switch to the internal boot mode?

  When you debugger meet the can't boot issues, normally, it is caused by the invalid image, but, it is easy to resolve it, just do the mass erase, if you still have issues, you also can enter the serial download mode do the mass erase, then JLINK should can debug it again.

Wish it helps you!

Best Regards,
