What version of arm-non-eabi-gcc are you using? Some older versions do not automatically infer Thumb mode from the -mcpu=cortex-m0plus option. We recommend using at least version 7.3.1.

Alternatively, you can try adding FLAGS += -mthumb to the file basicloader/build/makefiles/stm32lx.mk below the line that says FLAGS += -mcpu=cortex-m0plus.
