5 years ago Hey, thanks for reaching out!
Both versions of the board have uncommitted board defs for the bootloader, the wroom is from when it was still called uf2-samd and the wrover is more recent and a combo of the feather m4 and the pyportal. I'll probably come back to the wroom at some point but I'll likely get the wrover committed first as I'm actively working on that version. If you're interested in hacking on it yourself you can compare the different board defs in the bootloader to see what the options are and use that to guide you. I should have a PR in by the end of the week.
The board def in the CP repo is for the wrover version which uses a J20 and was hastily updated from the G19 based wroom version, hence the mixup you pointed out.

Hi, I don't know where to ask questions elsewhere...
Do you use the "normal" ItsBitsy UF2 Bootloader for the 48pin variant of the CP32-M4 ? (from here: https://github.com/adafruit/uf2-samdx1/releases) even though the board has crystal ?
I thought, I found a board variant for CP32-M4 in the circuitpython repo: https://github.com/adafruit/circuitpython/tree/master/ports/atmel-samd/boards/cp32-m4 but in there is written in "mpconfigboard.mk": "# No I2S on SAMD51G" "CHIP_VARIANT = SAMD51J20A" so I think this is a little mixed up (?)
