@tnt Just a guess: Did you check bit order? Big/Little Endian? Maybe you want to read address 0x4800 but the IC responds with the content of 0x0012?
The IC seems to support several conventions, see 0x480A, the default (0x00) being … undocumented.

@teilweise No, some of the registers match their description and are consistent with the init values. You can find linux kernel drivers for this module but they pretty much rely on hard coded init sequence for the most part. But when you parse those, some register will match and things like PLL param or image size match. But then some other part write to undocumented register. And none of those drivers have init for single lane mode.
