开源软件名称（OpenSource Name）：glegrain/STM32-with-macOS开源软件地址(OpenSource Url)：https://github.com/glegrain/STM32-with-macOS开源编程语言(OpenSource Language)：C 98.8%开源软件介绍(OpenSource Introduction)：Using GCC and Makefiles on macOS to build STM32CubeMX projectsAs of v4.21.0, STM32CubeMX is now capable of generating Makefiles that can be used to build projects using the GNU ARM Embedded Toolchain. Makefiles allow you to be IDE independent and use you favorite text editor. For some people, IDEs are slow and take up a lot of resources. With a Makefile, building your project is as simple as typing Although this tutorial has been written with macOS in mind, similar steps can be applied to Linux or Windows machines.
0 - Installing the toolchainRequirements:
After the Command Line Tools were successfully installed, the remaining toolchain requirements can be installed using Homebrew.
If the above command does not work, you could try installing And Java 8 will be installed at Pro Tip: Create a symbolic link to one of the binary directory searched by your Then, 1 - Create a Project using CubeMXIf you are also using an NUCLEO-L476RG, you can use the example "blinky" project by cloning the following repo: Alternatively, you can generate you own project:
For more information, refer to the STM32CubeMX User Manual available on st.com. Usefull sections include:
2 - Configure your MakefileUnfortunately, Makefiles generated by CubeMX do not work out-of-the-box. You need to edit the file and set your compiler path. Luckily, this step only has to be done once. Later on, if you want to add source, header files or simply change your compiler options, refer to the [Editing your Makefile] section for more details.

Then use the Pro Tip: for faster build time, If all goes well, you should see a result without any errors or warning: Pro Tip: The Makefile generated by CubeMX comes with a predefined rule called 4 - Programming the boardOption 1 - Using STM32CubeProgrammer GUI:
Note: Because STM32CubeProgrammer is still relatively new, chances are you will have to upgrade your ST-Link firmware. For more information, you can refer to the STM32CubeProgrammer User Manual Option 1.1 - Using STM32CubeProgrammer CLI:Below are some example commands to erase and program the target using STM32CubeProgrammer CLI: Option 2 - Using texane stlink:If all you want to do is program the board, then run any of the following commands: Otherwise, to program and debug run the gdb server with: Option 3 - Using OpenOCD:OpenOCD requires a a configuration file. If you installed openOCD using Homebrew, list of provided configuration ( For example, you could the following command to program and verify using elf/hex/s19 files. Verify, reset and exit are optional parameters. Binary files need the flash address passing. More examples and documentation available here 5 - DebuggingBecause you will be debugging a remote target device, GDB needs to connect to a gdbserver compliant debugger. Before launching GDB, you need to start a GDB server using your debugger to act as an interface between GDB and your device. Step 1 - Start a GDB serverOption 1.1 - Using texane stlinkOption 1.2 - Using OpenOCDStep 2 - Launch GDB:
Here is my file "./build/Example_Project.elf"
# Connect to texane stlink gdb server
target extended-remote :4242
# Or, connect to openOCD instead
# target remote localhost:3333
# monitor reset init
# monitor halt
# Uncomment to enable semihosting
# monitor arm semihosting enable
# Flash program and load symbols
load
break main
# Run to main (first breakpoint)
continue
Pro Tip: Launch GDB in GDB in Text User Interface (TUI) mode to show the source file and GDB commands in separate windows: Step 3 - Using GDBProgram stepping/execution:https://sourceware.org/gdb/onlinedocs/gdb/Continuing-and-Stepping.html Step over (step to next line of C code without going into functions): (gdb) next
90 SystemClock_Config();
(gdb) n
97 MX_GPIO_Init();
(gdb) Step into (step to next line of C, goes into functions): (gdb) step
SystemClock_Config () at ./Src/main.c:124
124 {Note: Use Return from a function: (gdb) finish
Run till exit from #0 SystemClock_Config () at ./Src/main.c:124
main () at ./Src/main.c:97
97 MX_GPIO_Init();Run until next breakpoint: (gdb) continue
Continuing.Pro Tip: for most command, you can simply type in the first letter. e.g. Pro Tip: Press enter to repeat the previous command. Very usefull to quickly step trough a program. Pro Tip: gdb also supports TAB completion. e.g Pro Tip: Use Setting a breakpoint:https://sourceware.org/gdb/onlinedocs/gdb/Breakpoints.html#Breakpoints http://www.unknownroad.com/rtfm/gdbtut/gdbbreak.html From there, you can add breakpoints using any of the following methods in the GDB command: Break on line number and run until breakpoint: (gdb) break main.c:107
Breakpoint 2 at 0x800208e: file ./Src/main.c, line 107.
