Cortex M with LLVM toolkit.

Example firmware for cortex-m using LLVM toolchain.

Tested well with LLVM/CLANG 6.0 or high from LLVM download site

Usage

This project provide a simple makefile set for working with LLVM/CLANG on cortex-m. Due to configure your target you need:

• Modify config.mk with preferred parameters for your project (self explained into file)
• Ensure memory configuration is correct for your MCU (on lib/mem.ld)
• Ensure linker script is correct (review lib/link.ld)
• Add vendor dependent reset vectors to src/start.c

Next, add your sources to src/*.c or modify Makefile to include others directories

Makefile targets

• all: Compile and link all files. Produce elf, bin, list and map
• clean: Remove compilation results
• size: Print size of result binary
• list: Create list file using objdump (llvm version)

Required packages

• clang 6.0 or higher
• llvm 6.0 or higher
• lld 6.0 or higher
