LPC43XX M4+M0app debug issue "failed to execute MI command"

a_bet — Thu, 18 Jun 2020 08:43:12 GMT

I'm on a journey to implement a multicore application on the LPC4370.
I'm trying to lay the basis and understand multicore projects and how to debug hem before adding stuff.

At the moment I created a M4+M0app project.
Memory configuration for M4:

The M4 core executes code from FLASH, while the M0app from RAM2:

Memory configuration for M0:

The problem is that I can't debug the projects successfully:

Can stop the M4, but not set breakpoints
Can not interact with M0 (leads to "failed to execute MI command -exec-interrupt").

Here's a video where I show a session of debug. Note that I am using LPClink2 and it is working as I can correctly debug other single core projects.

Thanks in advance,
Andrea
