Hi All,

Application stops in following steps,

(source/vendor/nxp/mcu-sdk-auto/SDK_MEK-MIMX8QM/boards/mekmimx8qm/ demo_apps/ rear_view_camera/ cm4_core1/ isi_board.c)

/* Delay at least 3 pixel clock. */

{
}

Thanks & Regards,

How to fix the source code without   LVDS to  HDMI Adapter（IT6263）,  I will connect to LVDS pannel direct.

Hi Wanben,

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

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.

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,
