Test Example

For HDMI Output

The following command shows an example for testing the HDMI output. 
modetest -M starfive -D 0 -a -s 116@31:1920x1080 -P 39@31:1920x1080@RG16 -Ftiles
The following list provides explanations for the parameters in the above example command.
  • 116@31:1920x1080 - <Connector ID>@<CRTC ID>: <Resolution>
  • 39@31:1920x1080@RG16 - <Plane ID>@<CRTC ID>: <Resolution>@<Format>

For MIPI Output

The following command shows an example for testing the MIPI output. 
modetest -M starfive -D 0 -a -s 118@35:800x480 -P 74@35:800x480@RG16
The following list provides explanations for the parameters in the above example command.
  • 118@35:800x480 - <Connector ID>@<CRTC ID>: <Resolution>
  • 74@35:800x480@RG16 - <Plane ID>@<CRTC ID>: <Resolution>@<Format>

For RGB2HDMI Output

The following command shows an example for testing the MIPI output. 
modetest -M starfive -D 0 -a -s 118@35:1920x1080 -P 74@35:1920x1080@RG16 -Ftiles
The following list provides explanations for the parameters in the above example command.
  • 118@35:1920x1080 - <Connector ID>@<CRTC ID>: <Resolution>
  • 74@35:1920x1080@RG16 - <Plane ID>@<CRTC ID>: <Resolution>@<Format>

For Both MIPI and RGB2HDMI Outputs

If your board is connected with both a MIPI and a RGB2HDMI output devices, the following commands show an example for testing on each of them.
  • For MIPI: 
    modetest -M starfive -D 0 -a -s 120@35:800x480 -P 74@35:800x480@RG16
    • 120@35:800x480 - <Connector ID>@<CRTC ID>: <Resolution>
    • 74@35:800x480@RG16 - <Plane ID>@<CRTC ID>: <Resolution>@<Format>
  • For RGB2HDMI: 
    modetest -M starfive -D 0 -a -s 118@35:1920x1080 -P 74@35:1920x1080@RG16 -Ftiles
    • 118@35:1920x1080 - <Connector ID>@<CRTC ID>: <Resolution>
    • 74@35:1920x1080@RG16 - <Plane ID>@<CRTC ID>: <Resolution>@<Format>
