HI. I’m trying to connect a Kyocera TCG058WXLPAPNN-AN30 touchscreen which uses a Goodix GT911 chip. The pinout is this:
The board it’s obviously different but the pinout of the 7J1 matches.
I tried quite some overlay for Raspberry PI (firmware/boot at master · raspberrypi/firmware · GitHub and others) but I’m unable to adapt any of them to my board. The error while I’m merging the overlay is “FTD_ERR_NOTFOUND”.
I think it’s due to the I2C chip (designware hdmi i2c-1): no matter what I can’t get the correct response from “i2cdetect -y 1”

I “modprobe” a few modules too: i2c-hid-of-goodix, goodix-ts together with others but no response from the touchscreen.
FYI: I tried to make it working with Ubuntu, Debian & Raspbian: same result!
Have you any suggestion?
Thanks.
