Hi
We are use DS90UB954 and DS90UB953 serdes to connent camera module and host. Basic data follow is
Host->TI954->LVDS->TI953->IMX390. We want to use exteral GPIO from host to trigger IMX390 frame sync.
The trigger GPIO0 from TI954 will be used as trigger pin. And TI953 GPIO3 is connected with IMX390 frame sync pin.
But we found pull/down GPIO0 can't trigger GPIO3 signal. Below is our setting, pls help review and give right register
config. Thanks
