MCUXpresso IDE v24.12 [Build 148] [2025-01-10] doesn't suppoert Debug Confguration "Variables"

Hello everyone,

I am using MCUXpresso IDE v24.12.148 with a SEGGER J-Link debugger. My project, RSR1138_OSRAM_CONFIGURABLE, has two build configurations: Debug and Release.

My goal is to have a single Debug Configuration that automatically points to the correct .axf file based on the active build configuration. Currently, I have two separate Debug Configurations, each pointing to a fixed path (Debug\...axf or Release\...axf), and I want to merge them into one.

I noticed that in the Debug Configurations -> Main tab, next to the "C/C++ Application" field, there is a "Variables..." button. Among the available variables, I found active_core_build_dir, whose description is: "The build directory for the active Core Build configuration for the given project".

Based on this, I modified the "C/C++ Application" field as follows:

text

${active_core_build_dir}/RSR1138_OSRAM_CONFIGURABLE.axf

I also set the "Build (if required) before launching" -> Build Configuration to "Use Active".

However, when I launch this Debug Configuration, I get the following error:

text

'Launching RSR1138_OSRAM_CONFIGURABLE JLink Debug' has encountered a problem.
Program file does not exist
\RSR1138_OSRAM_CONFIGURABLE.axf not found
\RSR1138_OSRAM_CONFIGURABLE.axf not found
\RSR1138_OSRAM_CONFIGURABLE.axf not found

It seems that the variable ${active_core_build_dir} is not being expanded correctly in the "C/C++ Application" field, resulting in a malformed path.

My questions:

Is it possible to use ${active_core_build_dir} or a similar variable in the "C/C++ Application" field of a Debug Configuration to create a dynamic path?
If yes, what is the correct syntax or configuration to make it work?
If not, what is the recommended way to achieve a single Debug Configuration that automatically selects the correct .axf file based on the active build configuration?

I have attached two screenshots:

One showing the Debug Configuration with the variable inserted and the resulting error.
One showing the "Select Variable" dialog with the list of available variables.

Thank you for your support.

Best regards,
Paolo Bernasconi
