After enabling i2c-1 in config.txt it does not show up (ls /dev/), instead one only sees i2c-11 and i2c-12. Seems i'm not the only one with this problem: https://www.raspberrypi.org/forums/view ... 3&t=302999 I'm not the OP.
From the linked thread: $this->bbcode_second_pass_quote('', 'A')nother way is change "dtoverlay=vc4-kms-v3d" to "dtoverlay=vc4-fkms-v3d" in config.txt.
