Question
Hot to do a discovery using Device authentiction
Did numerous builds using CubeIDE (10,000 lines of code). this error started coming up. "reason was unknown target"
Got the following message:
Make -j4 all DriversSTM32L4xx_HAL_Driver/subdir.mk.91: *** unable to generate command line. stop. "make -j4 all" terminated with exit code 2. Build might be incomplete. Build failed. 1 error 0 warnings
Cannot clear the problem. In IDE Debug configurations, Project, Tool settings, MCU settings ---There is nothing in the MCU and board (Custom board) slots.
