is that useful?

yes - it looks like there is a kernel option missing which seems to be enabled on pmos i guess:

$ grep GOODIX config.mt8
CONFIG_TOUCHSCREEN_GOODIX=m
# CONFIG_I2C_HID_OF_GOODIX is not set

i'll add that to the kernel config soon

hexdump0815 commented 1 year ago

i have added the config option now ( https://github.com/hexdump0815/linux-mainline-mediatek-mt81xx-kernel/commit/2a75a38af57c7267e00931fa8d71810759e9fb41 ) and added a test kernel with it built in here: https://github.com/hexdump0815/linux-mainline-mediatek-mt81xx-kernel/releases/tag/6.1.51-stb-mt8%2B ... here is some info about how to install a different kernel: https://github.com/hexdump0815/imagebuilder/blob/main/doc/installing-a-newer-kernel.md

Just because it defaultly boot from the root fs on mmcblk but not usb......yes, touch screen works, but the system seems to get swapped x and y value from touch screen.

refering to https://wiki.postmarketos.org/wiki/Lenovo_IdeaPad_DuetChromebook(google-krane), I set an udev rule, but nothing changed, and after switch to gnome, the touchscreen works fine...
