Than you Xu Ji,

rear view camera demo is working (Needs to connect HDMI Monitor at J8 connector of LVDS Port as per schematic (SPF-29420_C2.pdf) instead of J7 Connector.)

Thank You,

Hi Joan,

How can I change this demo from LVDS1 I2C1 to LVDS1 I2C0 ? because my board use i2c0 instead of i2c1 ?

Thank you!.

Hi bin wang,

You have to configure the MUX pin configuration in pin_mux.h file in M4 MCU side#. As well you have to configure in dts file in Kernel side.

Check the I2C MUX pin configuration (It's already used or not)

Hi Wanben,

If you are not using external adapter, undefined APP_DISPLAY_EXTERNAL_CONVERTOR from isi_config.h file
