I am using UC-599 on balenaFin board with Raspberry PI CM3 under Ubuntu 20.04  
It works fine with some version of libarducam\_mipicamera.so (V4L2 does not work - there are some threads on this forum about this). Now i replaced it with UC-788 and it does not work. I2C logical analyzer shows, that inside init\_camera call libarducam\_mipicamera speaks to I2C addr 0x60, sends 4 zero bytes, than speaks to slave address 0x6C. UC-599 responds and works, but UC-788 does not respond and initialization fails. Both cameras are OV9281 based. Maybe somebody can give advise?
