i.MX RT 1176 Dual Core Debug

[damonyun]

下载了MCUXpresso上最新的SDK 2.9.0，但是无论是使用DAP或者jlink swd都没办法调试 Cortex-M4内核，这部分有什么特殊设置吗？

Hi damonyun,

在SDK的example里有一个multicore_examples目录，里面有一些双核的工程。这些工程都可以同时调试M7和M4核。你只要import M7的工程，M4的工程会自动import。编译之后下载M7工程，M4工程也可以自动在同一个界面里调试。无论用CMSIS-DAP还是JLINK都可以这样调试。

你可以在mcuxpresso.nxp.com里下载一个SDK document包。里面有Getting Start文档。3.4节讲了怎样建多核工程。

Hi @jingpan

I have the same question as @damonyun , how do you debug the Cortex M4 specifically?

I am aware of the multi-core projects, and how they work.

I would like to know how one can debug the cortex m4 core ONLY, as I am trying to write an application for it.

Kind regards

Hi,

You can debug M4 core only by fill '1' to Run->Debug Configure->LinkServer Debugger->Override core index. This is only for CMSIS-DAP.
