Can't debug on Mac

[stanimirsp5]

Has anyone succeded to run avr_debug on Mac? I'm using VS Code for Mac with Arduino extension and now I want to be able to debug my program but there are a lot of obstacles in configuring the launch.json file.

• First for 'miDebuggerPath' the documentation says to set the path to avr-gdb. But there isn't avr-gdb. I searched for it in the Arduino IDE 2.0 directory but such a file doesn't exist. So I downloaded AVR 8-Bit Toolchain (OSX) from microchip website. When I run it constantly throws that error.

• My next problem is with miDebuggerServerAddress. What value to set there? My Arduino runs on /dev/tty.usbmodem142401 serial port. When I set that value the vs code enters an endless loop.

• Also I can't turn off compiler optimizations because such path hardware/arduino/avr in Arduino IDE 2.0 directory on Mac doesn't exist

So my biggest problem is with paths especially because documentation is strictly for Windows and it's very hard and time-consuming to search workarounds for Mac. So if anyone has succeeded in running the avr_debug on Mac, please tell me:

• where in Arduino IDE to find 'avr-gdb'?
• what value for 'miDebuggerServerAddress' to set?
• where in Arduino IDE to place 'platform.local.txt'?

This is how my Arduino.ino file and my launch.json file looks like code snippet

Thanks for your time.

Hi,

one way to get a decent avr-gdb on a Mac is using homebrew! Install the homebrew system and then:

brew tap osx-cross/avr && brew install avr-gdb

You can copy the binary which you find following the link at /usr/local/bin/avr-gdb to the place where you need it, or you simply set the path to that link.

The hardware folder on a Mac can either be found in the Application itself (you need to open the corresponding folder) or it is below ~/Library/Arduino15 (or both).

Hi, @felias-fogg, thanks for your answer it was very helpful. I overcame my issues with the launch.json and I think everything is fine with the JSON file. This is the updated version link

Now my problem is that when I upload my code to Arduino and run the debugger it enters in loop and vs code begins constantly to load something. I thought the problem may be with Baud rate but I know that the debugger uses 115200 and the default baud rate for Arduino extention is 115200 too.

Hi @stanimirsp5,

I did not try it out yet - I still have to install VSC and the Arduino extension. However, the default baud rate of avr-gdb is 9600! So you need to tell avr-gdb to switch to 115200. Either use set serial baud 115200 after avr-gdb started and before you establish a connection with target remote ... or call avr-gdb with the argument -b 115200.
