Factory Test & Debugging

[TheBakedPotato]

I am attempting to make my way through moving the factory tests over to PlatformIO. I have just been trying to familiarize with that ESP32 platform and Arduino framework to have a better understanding of what the various structs/functiom calls actually do.

As well, at home I have an ESP32-C3. Specifically the ESP32-C3-Rust-Dev-Kit. It's a single RISC-V core oppose to I believe the two core Xtensa processor used by Krake, but works fine for this. I'm trying to get the debugger through PlatformIO connected to it, and serial output, but I'm currently unsuccessful. The ESP32-C3 dev kit I believe has a built in JTAG debugger.

Anyways, I am trying to figure that out as I go ahead and try to move all "Factory Test" code into a single project and to PlatformIO

Oh my goodness, I figured it out. In the platformio.ini file, the debug_tool needs to be set to the right value. Since ESP32 boards have built in debuggers the line debug_tool = esp-builtin needs to be added to platformio.ini. This is for my C3 board, but an example .ini file would look like

[env:esp32-c3-devkitm-1]
platform = espressif32
board = esp32-c3-devkitm-1
framework = arduino
debug_tool = esp-builtin

With that line it debugs properly! Honestly, kudos to PlatformIO, it genuinely is pretty much seamless to get a board setup and debugging.

The problems I'm having with the Serial instance not outputting is because I believe it simply has the wrong UART pins configured. The Rust dev kit has a slightly different hardware configuration than the regular C3 dev kit so to get serial out I might just have to define a new HardwareSerial instance with the correct UART port.

Anyways, this is all wonderful news meaning I can continue making some progress towards updating the "Factory Test" files and better understanding the full ecosystem we will be working with :)
