• /Core
  • main.c
  • User can add user.c/user.h in this folder.
• /Device_Startup
  • _syscall.c system call function. (provide by Nuvoton M480 BSP)
  • gcc_arm_.ld linker script. (provide by Nuvoton M480 BSP)
  • startup_M480.S startup file. (provide by Nuvoton M480 BSP)
• /Drivers
  • CMSIS (Common Microcontroller Software Interface Standard) , including ARM core related files. (provide by ARM)
  • Device, Register Layer. (provide by Nuvoton M480 BSP)
  • StdDriver, Hardware Abstract Layer. (provide by Nuvoton M480 BSP)
• /UnitTest
  • User can add test.c here. Every test.c will build separately (Every test.c should include its own main() function).

How to use?

The following command can be used.

• make This command will build the sources file in /Core, /Device_Startup, /Drivers. The exact files can be set in Makefile variables C_INCLUDES and C_INCLUDES.
  • create \build folder, and the following output files will be put here.
  • compile the sources file separately.
  • link the depedency object files.
  • use the arm-none-eabi-objcopy to translate the ELF file to .hex or .bin.
• make test This command will build the sources file in /UnitTest, /Device_Startup, /Drivers. The exact files can be set in Makefile variables C_INCLUDES and C_INCLUDES.
• make macro This command will preprocess source files in /Core, /UnitTest, /Device_Startup, /Drivers, for debugging.
• make size This command will use the arm-none-eabi-nm tool to analyze the ELF file.
• make clean This command will clean all of the build files. (The /build folder)
