LPC55S36-EVK no contact via debugger after running TrustZone example

jpholme — Thu, 19 Sep 2024 09:14:45 GMT

I have tried out the TrustZone examples that comes with the LPC55S36 SDK from NXP's website using the IAR EWARM environment. I could debug this nicely and jump from secure start-up into the nonsecure part of the simple Hello World example.

Suddenly, however, I am locked out and can't debug anymore. Using BLHOST and starting the ISP-bootloader, I can run a ".... get-property 17" and see that the bootloader is now in SECURE mode. How did it jump in there?

And I suppose this is irreversible?

And can I do anything to get back to debyugging?
