Triton Mini with date code 2021/07/08 is possibly non B chip variant #1
Description
I had a hard time getting QMK to work on the 2021/07/08 revision of the Triton Mini, which turned out to be caused by a wrongful assumption of mine. I assumed the HFD2201KBA was the SN32F248B. The chip in my keyboard was marked HFD2201KBA (with the rest of the engraving being 216MNWA0e), but the core of it turned out to be the SN32F248 without the "B". These two variants, the SN32F248B and the SN32F248 are not pin compatible, so the ports and pins were all wrong. Differences described in page 16 of SN32F240B_V1.9_EN.pdf and page 20 of SN32F240_V2.1_EN.pdf.
It might be possible possible to spot this difference by inspecting the VID/PID, as any official FW-flasher needs to be mindful of the actual chip. However I did not investigate further, as remapping the pins solved my problem.
I have not heard of this core ambiguity of the HFD2201KBA elsewhere, but this was certainly the issue whith my Svive Triton Mini 2021/07/08. I made a comment about it on the SonixQMK discord, but have not documented my findings otherwise.
