GPT demo (SDK 2.3.1) runs once on EVKB then 1052 needs to be mass erased

I have the gpt demo imported into a new workspace from SDK v2.3.1. I modified the demo to run with SDRAM support instead of SRAM (reordered memory sections, allocated stack/heap to SDRAM and added preprocessor define SKIP_SYSCLK_INIT)

The demo runs as advertised on MIMXRT1050-EVK. On this eval kit type, you can terminate debug mode and re-enter and resume at will.

On the EVKB-IMXRT1050 the demo runs after loading the first time, but when the project exits debug mode the IDE throws errors.

Despite the IDE showing to be out of debug mode, it seems debug mode did not terminate. This dialog popped up after I disconnected the EVKB from my laptop.

Restarted MCUXpresso IDE and reconnected EVKB to PC. Attempted to enter debug mode and I got:

My only recourse now is to mass erase the EVKB.

I attached the exported project from MCUXpresso IDE.

This is the first of two issues I have with the GPT demo. I will ask describe the second issue in a separate post.

We will investigate. But can you please just confirm - did the original demo work OK on both boards? i.e. was the problem triggered only when you made modifications to use SDRAM?

It seems the run-once-and-bail-until-mass-erased issue on EVKB-iMXRT1050 occurs on the original project imported from the SDK as well that is running out of flash but using SRAM.

Steps to reproduce:

1. mass erase EVKB-iMXRT1050

2. restart MCUXpresso IDE and import gpt driver demo from the SDK

3. build and debug the gpt demo - gpt interrupt tick is visible on terminal via UART

4. attempt to terminate gpt demo -- same type of dialogs indicating failure to terminate

I attached an exported version of my test project.

For reference I also attached a snapshot of my EVKB with SN and rev info.
