iMXRT 1024 evk debug error

Hello,

We are trying to debug a Secondary bootloader for IMXRT 1024 using the iMXRT 1024 evk board and MCUXpresso IDE. Whenever the debug session is launched, we get the following error:

What is the cause of this issue? Hoe can it be fixed?

Re: iMXRT 1024 evk debug error

Hi @cleo ,

Thank you so much for your interest in our products and for using our community.

I don't think this issue is caused by the secondary bootloader itself.

From the debug log, it appears that MCUXpresso IDE / LinkServer is running the following connect script:

IMX93_connect_M33.scp

IMX93 M33 Connect Script

This script is intended for the Cortex-M33 core on i.MX93 devices. However, the i.MX RT1024 is a single Cortex-M7 device and does not use the i.MX93 M33 connection flow.

Could you please try below?

1: In MCUXpresso IDE, delete the existing debug launch configuration for this project.

2: Confirm that the project MCU/board is configured for an i.MX RT1024 device (or RT1024 EVK), not an i.MX93 device.

3: Open the launch/debug configuration and verify that the selected device/core is RT1024.

If possible, You can also share a screenshot of the Debug Configuration settings for further review.

Wish it helps you

Best Regards

May
