2.9.3. Display

The max HDMI resolution supported by AM62x Starter Kit (SKEVM) is 1920x1080@60. The default SD card image included in Processor SDK already has HDMI support enabled. In order to test the display, connect the HDMI monitor to the SKEVM as shown by below picture.

Next, power on the board and wait for the Linux prompt to appear on the Linux console. After successfully booting the SKEVM, run the below commands to test the display connection:

# /etc/init.d/weston stop

# kmstest
Connector 0/@39: HDMI-A-1
  Crtc 0/@37: 1920x1080 148.500 1920/88/44/148/+ 1080/4/5/36/+ 60 (60.00) 0x5 0x48
  Plane 0/@31: 0,0-1920x1080
        Fb 49 1920x1080-XR24
press enter to exit

After executing the above test, the following image will be generated:

The below color pattern should be observed on the screen (left to right):

Red -> Green -> Blue -> Cyan -> Magenta -> Yellow -> White -> Black

The modetest command could also be used to query all the resolutions, connector ID and plane ID of the connected monitor:

# modetest -M tidss
