[device-report] Royal kludge RK G68 about sinowealth-kb-tool HOT 1 CLOSED

@Chumet thanks for the report! Especially for those PCB pictures. I should make this part of the issue template so that more people are encouraged to provide them :)

I have been able to read without problems, now I want to flash the VIA firmware, there is one called rkg68_via.hex here: https://www.caniusevia.com/docs/download_firmware, I can use sinowealth-kb-tool to write this firmware? Do you think I can leave it like a brick? I would like to be able to use the entire VIA or QMK environment

QMK (with VIA) will most certainly not work as it's designed specifically for ARM and AVR architectures and the SH68F90A is an 8051 based microcontroller. There must be other variants of this keyboard with an ARM mcu (sonix SN32F268?) which can support QMK.

8051 isn't supported by mainstream compilers like gcc or llvm, and the most popular oss compiler that does support it is sdcc, but it lacks many features that QMKs code relies on, making porting it non-trivial (among other issues).

If you're interested in developing firmware for keyboards like this one, you might want to check out smk, but be warned that it's still in experimental/pre-alpha stage, I don't recommend it for general usage and it is provided as-is with no additional support.
