Why is my 12.1" display not supported in LogicLoader 2.3.1 for the i.MX31 SOM-LV? How can I work around this?

The release of LogicLoader 2.3.1 did not include display modes for Logic's 12.1" display kits. To see the supported modes, type:

losh> help video-open

Until we release a version of LogicLoader with these modes, you can use the following commands to set up modes in the configuration block in LogicLoader. This will allow you to use the video-open, draw-test, and bitmap commands.

Instructions:

  1. The following command should be run once on your board to create the configuration block. See the LogicLoader manual for more information.
    losh> config CREATE;
    for LCD-12.1-SVGA-10 Display Kit: (future LogicLoader mode 2)
  2. Use the following script:
    losh> video-init 5 16; w /w 0x53FC00C0 0x005D001B; w /w 0x53FC00D0 0x13F40000; w /w 0x53FC00D4 0x0E7C0001; w /w 0x53FC015C 0x00C00042; config V 121 800 600;
  3. power off
  4. power on
  5. Use the following command to open the new mode:
    losh> video-open 121 16; draw-test;

For use in Windows CE:

  1. Use the ‘video-open 121 16', in LogicLoader.
  2. When using the ‘exec' command to boot Windows CE, make sure to put the following in the boot parameters.
