How can I program a custom board using external mini simplicity debugger?

[abhaysbharadwaj]

I have created a custom sensor board using the MGM240P (same pin outs as the sparkfun matter board) and would like to use an external mini simplicity debugger (SI-DBG1015A) to program it.

I tried downloading the bootloader, but the IDE could not detect my debugger. I have simplicity studio and the JLINK pack installed.

P.S. I am able to use simplicity studio to code and flash, but would want to work with Arduino core to port a couple of existing projects to use MGM240 and Matter with SiLabs.

I get the following error when I try to upload any sketch:

WARNING: Can not look up target device automatically because adapter is in debug mode OUT.
ERROR: A target device must be specified using the --device option.

A small update.
Workaround implemented is as follows:

1. write the sketch in Arduino
2. use "Export compiled binaries" option
3. Use simplicity studio's "Simplicity commander" >> Flasher
4. Flash the "sketch.hex" to your Device. (Use the "sketch_with_bootloader.hex" incase you have selected the bootloader as Metter or BLE)
5. Program starts to work.

Now, having said this, I would still love to do this completely inside the Arduino IDE. Similar to how the STM32 core or the ESP32 core helps you use a "Generic family" and select the "IC Variant" and uses that to compile the code and upload to target, if something like this could be implemented in SiLabs core, it would be damn useful for custom board projects!
