RPi5_hdmi_in_card

Raspberry Pi5 HDMI to CSI-2 input card based on TC358743

I created this tutorial to help the community enable cheap HDMI to CSI-2 cards like Geekworm C790 based on TC358743 The script intends to automatically detect the media device that keeps changing every boot

STEPS

1- Modify the config file

    sudo nano /boot/firmware/config.txt

2- Add/Modify the entries below

    dtparam=i2c_arm=on
    dtparam=i2s=on
    dtparam=spi=on
    dtparam=i2c_baudrate=10000
    dtparam=i2c_vc=on
    
    camera_auto_detect=0
    
    dtoverlay=vc4-kms-v3d,cma-512
    max_framebuffers=2

    [all]
    dtoverlay=tc358743,4lane=1
    dtoverlay=tc358743-audio

3- Copy the hdmi2csi2card with all files to you RPi5

4- Run the enablehdmi.sh script with bash

Make sure the device is connected to the HDMI IN

    bash enablehdmi.sh

The script is fully customizable. You can play with the variable and change the detection resolution.
