Flash Stubs

These are simple routines for programming the flash on various Cortex-M microcontrollers. The routines should be provided with the naked attribute as the stack may not be available, and must not make any function calls. The stub must call stub_exit(code) provided by stub.h to return control to the debugger. Up to 4 word sized parameters may be taken.

These stubs are compiled instructions comma separated hex values in the resulting *.stub files here, which may be included in the drivers for the specific device. The drivers call these flash stubs on the target by calling cortexm_run_stub defined in cortexm.h.
