MIPI interface[edit | edit source]

There are two MIPI camera inputs and one MIPI display output available on the Evaluation Kit.

Description[edit | edit source]

The MIPI camera interfaces are available on the Evaluation Kit at the connectors J5 and J6.

The MIPI display interface is available on the Evaluation Kit at the connector J7 (and it is located at the bottom side of ORCA SBC)

J5, J6 and J7 are a 22x1x0.5mm horizontal ZIF connectors that deliver the MIPI signals, many control signals and power.


MIPI camera J5 connector
MIPI camera J6 connector
MIPI DSI J7 connector

Device mapping[edit | edit source]

The MIPI CSI peripherals are mapped to the corresponding /dev/video<X> device in Linux.

The MIPI DSI peripherals are mapped to the corresponding /dev/fb<X> device in Linux.

The devices mapping depends on the device tree configuration.

Device usage[edit | edit source]

The devices are accessed in Linux through the standard graphic stack.
