This repository is my personal project to build a custom build system for EFM MCU family
Install arm-none-eabi tool chain from ARM website. After the installation, move the bin files with prefix arm-none-eabi- to system bin directory or any directory. Then add the path to the bin files to $PATH variable. Make sure to logout and login.
Edit Bin util and arm toolchain directory path for the host platform inside cmake/arm-none-eabi.cmake
set(ARM_TOOLCHAIN_DIR "path/to/binutil/") # set arm toolchain directory path
set(BINUTILS_PATH ${ARM_TOOLCHAIN_DIR}) # set binary utility directory path
Cross-compiling setting is configured by invoking the following cmake command
cmake -B build -D CMAKE_TOOLCHAIN_FILE=cmake/arm-none-eabi.cmake
Included following lines to suppress error regarding compiler configs
SET (CMAKE_C_COMPILER_WORKS 1)
SET (CMAKE_CXX_COMPILER_WORKS 1)
To build
cd build
cmake --build .
-specs options uses spec file specified by the string the spec files are inside the ARM lib folder /usr/local/gcc_arm/ARM/arm-none-eabi/lib
-Map=${PROJECT_NAME}.map this option requires -Wl, in front of it.
The issue regarding re-declaration of type is resolved by downgrading the CMSIS pack from 5-5.9.0 to 4.5.0
Programming flow command steps
connect
erase
loadbin /directory/to/binfile ...... /Users/sj/Documents/projects/efm-blink/build/EFM-Blink.bin 0
r - means reset
g - means go
Steps to running debugging environment
- open two terminal
- Run JLinkGDBServerCL -device EFM32G890F128
- On another terminal arm-none-eabi-gdb
- target remote localhost:portnumber/shown/on/JLinkGDBServerCL
- load, this programs the target and starts from the reset_handler
