+This repository contains a  makefile describing the functions of openocd & st-utils. 
+Using these files you can upload and erase the microcontroller firmware, and use GDB.
+
+st-utils is used only for stm32. openocd can be used for various microcontrollers, for example: WCH, Novoton, Geehy, GigaDevice.
+You can include flash_uploader.mk in you Makefile and use.
+
+Target:
+
+	make flash     : upload flash use OpenOCD
+	make erase     : erase flash use OpenOCD
+	make flash-st  : upload flash use st-flash
+	make erase-st  : erase flash use st-flash
+	make gdb       : open GNU debugger
