Hello,

what’s the difference of the i2c@546c0000 and i2c@7000C000 for Jetson Nano?

There’s no any different.

    aliases {
            i2c0 = "/i2c@7000c000";
            i2c1 = "/i2c@7000c400";
            i2c2 = "/i2c@7000c500";
            i2c3 = "/i2c@7000c700";
            i2c4 = "/i2c@7000d000";
            i2c5 = "/i2c@7000d100";

So can I use any of it for camera control via i2c mux?
I’m asking because in “Address map” of “Technical Reference Manual” for Nano, says i2c has address 7000:C000, but on this forum most of people use “i2c@546c0000”.

i2c@7000C000 {
       tca9548@70 {

or

i2c@546c0000 {
       tca9548@70 {

If you design your own carrier board you can use any of them, but for the devkit only have i2c bus 0/1 in the 40 pins header.

Is it depend on hardware design ? Can you please point to document where is it described?
