Mbed Studio Debugger not showing variables

Mbed studio shows a cryptic error message in Local Variables:

Unknown value for PRINT_VALUES: must be: 0 or “–no-values”, 1 or “–all-values”, 2 or “–simple-values”

I’m using Mbed Studio 1.4 with the default toolchain (armc6) against a STM Nucleo-F446ZE board.

This may be related to error messages that appear in the “Static” variables dropdown “Duplicate variable object name”, “Attempt to extract a component of a value that is not a structure.”.

Hi Dan,

Thank you for reporting this issue. We will investigate it.
