stm32-nucleo-l476rg-gnumake

The repository demonstrates how to import GNU Makefile, generated by CubeMX, into Eclipse and add STM32 debug profile.

1. Create Eclipse Project

Launch Eclipse on Mac OS X (as well as other platforms), and select File / New / Other, and select Makefile Project with Existing Code in C/C++ category:

In the project creation wizard dialog, please point the Existing Code Location to the /cubemx directory, and select Ac6 STM32 MCU GCC in toolchain list:

Then, an Eclipse project is created.

2. Build Project

On the project icon, right click to pop up the action menu, and select Build Project

3. Update Project for Ac6 STM32 Debugging

The project is still a C/C++ project that just uses cross-compiler to build. We cannot run the project as Ac6 STM32 C/C++ Application:

It's required to add Project Nature MCU Project to project workspace. First, open project settings:

Select Project Natures, and click ADD button:

Select MCU Project to add:

Finally we can run the project as Ac6 STM32 C/C++ Application:

4. Add Debugger Profile

Now, we need to add one debugger profile for Eclipse to use as default one. First, please add one openocd script at the project top directory: /cubemx/cubemx.cfg

# This is an nucleo-l476rg-nfc board with a single STM32L476RGTx chip
#
# Generated by System Workbench for STM32
# Take care that such file, as generated, may be overridden without any early notice. Please have a look to debug launch configuration setup(s)

source [find interface/stlink.cfg]

set WORKAREASIZE 0x8000

transport select "hla_swd"

set CHIPNAME STM32L476RGTx
set BOARDNAME nucleo-l476rg-nfc

# CHIPNAMES state
set CHIPNAME_CPU0_ACTIVATED 1

# Enable debug when in low power modes
set ENABLE_LOW_POWER 1

# Stop Watchdog counters when halt
set STOP_WATCHDOG 1

# STlink Debug clock frequency
set CLOCK_FREQ 8000

# use hardware reset, connect under reset
# connect_assert_srst needed if low power mode application running (WFI...)
reset_config srst_only srst_nogate connect_assert_srst
set CONNECT_UNDER_RESET 1

# BCTM CPU variables

source [find target/stm32l4x.cfg]

Select Debug Configurations in the popup menu by right clicking project icon:

New a debug profile:

In Main tab, click Search Project to find cubemx.elf from current project

In Debugger tab, please fill in these values:

1. GDB command: ${openstm32_compiler_path}/arm-none-eabi-gdb
2. OpenOCD command: "${openstm32_openocd_path}/openocd"
3. OpenOCD port: 3333
4. OpenOCD Configuration Script: select User-defined
5. OpenOCD Configuration Script: fill in Script File with ${ProjDirPath}/cubemx.cfg

Then, run current app with debugger.
