=== Device mapping ===
−
UART3 is mapped to <code>/dev/ttymxc2</code> device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernel.
+
The MIPI CSI peripherals are mapped to the corresponding <code>/dev/video<X></code> device in Linux.

−
=== Device usage ===
 
  
−
To connect to the debug serial port:
+
The MIPI DSI peripherals are mapped to the corresponding <code>/dev/fb<X></code> device in Linux.
  
−
# connect the DB9 adapter bracket to the J22 connector on the SBCX board
+
The devices mapping depends on the device tree configuration.
−
# connect a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)
 
−
# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1
 
  
 +
=== Device usage ===
 +
The devices are accessed in Linux through the standard graphic stack.

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.

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

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.
