    Rock PI 4

    two same addresses do not work on the same network, the other must be different (dhcp IP) "/dev/i2c-0 /dev/i2c-1 /dev/i2c-3 /dev/i2c-4" none is working

    w1 works "param_w1_pin=GPIO4_D5" ok how to find i2c root@rockpi:~# dmesg|grep i2c [ 1.543735] i2c /dev entries driver and root@rockpi:~# ls /dev/*i2c* /dev/i2c-0 /dev/i2c-1 /dev/i2c-3 /dev/i2c-4 i2cdetect find nothing
