RT1064+Jlink debug issue

colinluan — Sat, 24 Oct 2020 02:50:28 GMT

Hello,

My jlink suddenly couldn't connect to my RT1064 board, and now the J-link commander only can get the RT1064 information but cannot debug in MCUXPresso.

My debug environment:

IDE	CUXPresso 10.3.1
Debuger	Jlink Base
Debuger Driver	Jlink V6.84 Driver

1. The J-Link Commander can get the RT1064 information

2. MUCXPresso shows following error

and the jlink display following log:

3. My jlink configuration

Anybody has ever get this issue and give me some helps? thanks.

Hi colin,

Normally, this kind of problem is caused by application code has error and the core go into a unknow status. Please try to use MCUBootUtility to clear flash. You can download it from https://github.com/JayHeng/NXP-MCUBootUtility.

Regards,

Jing

Thank you for your help, I have resolved this issue by switching to serial download mode and clear all flash, then I can debug after switching to internal mode.
