Other Parts Discussed in Thread: SN65DSI83
Hi Team,
My customer got issue with M101GWWF panel, they can not get image from DSI bus but ok with test pattern.
It was work with XT70618 panel but doesn't work after change to M101GWWF,
Below is customer initial setting and panel spec.
Would you help us check if there is mistake with the setting below? thanks a lot.

};
