macOS M1 support?

[KenjutsuGH]

Is there any way to use this core on a M1 Mac?

I made progress in modifying the package_at32_index.json file and installing AT32F4 support in Arduino for macOS M1. Here's a summary of the steps:

1. I made changes to the package_at32_index.json file to include support for the M1 toolchain/compiler. For "Artery_ISP_Console", I copied the Linux entry, acknowledging that the Linux executable won't run on macOS. Here is my modified file: package_at32_index.json
2. With the modifications in place, I was able to install AT32F4 support in the Arduino IDE for macOS.
3. In the Arduino IDE, I enabled the verbose compile setting to obtain more detailed information during compilation.
4. The second-to-last line before the memory usage information in the compilation output, provided a link to the compiled hex file. In my case, it was located at /var/folders/tq/dqrghm993td49tz1pvg8psxm0000gn/T/arduino_build_563977/MyFirstSketch.ino.hex.
5. To flash the executable, I utilized openocd from ArteryTek. You can find the openocd releases on their GitHub repository. (ArteryTek openocd)
6. Tested with ST-Link V2 and WeAct Mini Debugger DAPLink (APM32).
7. For the DAPLink debugger, I executed the following command in the terminal: ./openocd -f interface/cmsis-dap-v2.cfg -f target/at32f403axx.cfg -c init -c "program /var/folders/tq/dqrghm993td49tz1pvg8psxm0000gn/T/arduino_build_563977/MyFirstSketch.ino.hex verify reset exit".

Now, if only ArteryTek can port their Linux version of Artery_ISP_Console to macOS...

I have added support for macOS on a M1 processor using OpenOCD as the upload method via a DAPLink adapter.

ST-Link was added via OpenOCD
