hardware/arduino/sam/cores/arduino/HOWTO - compiling a project.txt

1- Path to GCC ARM toolchain

Set into environment variables the ARM_GCC_TOOLCHAIN variable:
ex:
ARM_GCC_TOOLCHAIN=C:\CodeSourcery_2011.03-42\bin

2- Compile libsam (at91sam peripheral drivers)

Go to hardware/sam/system/libsam/build_gcc

run the command: 'cs-make'

This will compile the libsam library and deliver to main Arduino folder the files:

hardware/sam/cores/arduino/libsam_sam3s4c_gcc_dbg.a
hardware/sam/cores/arduino/libsam_sam3s4c_gcc_dbg.a.txt (result of nm)

3- Compile libarduino (Arduino API)

Go to hardware/sam/cores/arduino/build_gcc

run the command: 'cs-make'

This will compile the libarduino library and deliver to main Arduino folder the files:

hardware/sam/cores/arduino/libarduino_sam3s_ek_gcc_dbg.a
hardware/sam/cores/arduino/libarduino_sam3s_ek_gcc_dbg.a.txt (result of nm)

4- Compile libvariant (variant specific library, use Arduino API and libsam)

Go to hardware/sam/variants/sam3s-ek/build_gcc

run the command: 'cs-make'

This will compile the libvariant library and deliver to main Arduino folder the files:

hardware/sam/cores/arduino/libvariant_sam3s_ek_gcc_dbg.a
hardware/sam/cores/arduino/libvariant_sam3s_ek_gcc_dbg.a.txt (result of nm)

5- Compile test application

Go to hardware/sam/cores/arduino/validation/build_gcc

run the command: 'cs-make'

This will compile the test application and deliver the binary into:

hardware/sam/cores/arduino/validation/debug_sam3s_ek/test_gcc_dbg.elf
hardware/sam/cores/arduino/validation/debug_sam3s_ek/test_gcc_dbg.bin
hardware/sam/cores/arduino/validation/debug_sam3s_ek/test_gcc_dbg.map (mapping matching linker script)
hardware/sam/cores/arduino/validation/debug_sam3s_ek/test_gcc_dbg.elf.txt (result of nm)
