RT1064+Jlink debug issue

colinluan · ‎10-23-2020

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:

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.

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.
