Tapo C120(SSC377 ) Image Sensor isn't detected

[asyncbridge]

I'm trying to test the openipc on Tapo C120 (SSC377).
I've finished to write the openipc firmware(lite) for SSC377 to my C120 successfully but image sensor isn't detected while booting.

I checked C120 log as follows. The correct sensor is sc430ai but it didn't work.
