Dual Core Release debugging with PE Micro

DanielR — Wed, 21 Sep 2022 18:33:24 GMT

I am using the LPCXPRESSO LPC54102 EVAL BRD (OM13077UL) for developing a dual core project on the LPC54102. I have discovered that when I build my code in Release mode, I am no longer able to use the PE Micro Multi Link probe (connected via SWD)

When I try to launch the debugger, the master image loads fine, but then I get the following error when it tries to load and launch the slave image:

The PE Micro probe works in Debug mode and the J Link probe built into the eval board works fine in both Debug and Release mode. This is a problem, because in my final product, I will not have the built in J Link probe, I will only have the SWD port. Is this a limitation of SWD or the PE Micro?

Thank you,

Daniel

I am not sure what I was doing wrong yesterday. I did a clean and full compile on the Master and Slave and now the PE Micro probe seems to be working fine. I would still like to know what was causing the error yesterday.

Hello,

Thanks for your sharing.

It's hard to know exactly where the problem is, and yes, clean and compile is the commonly used method, also can delete folder .metadata under workspace to try.
