Question
Nucleo-L4A6ZG failure to program
I've just installed the latest version of STMCubeIDE on a Mac and am trying to flash a simple program generated by the IDE. I have installed the L4 pack.
The firmware on the ST-LINK has been updated.
I have no other ST boards and I am not sure if it is an issue with the processor support or my installation.
I get a "Problem Occured" popup with the details:
Error in final launch sequence:
