    Just got a LH7A400 -

    Even though the manual says that the board support LCD-5.7-QVGA-10,
    however when I type in

    video-open 3 16

    I get the following error

    Error, found no suitable display drivers
    Error, couldn't get a display handle

    The versio of Lolo on the board is Version_release_1=2-pre1.2.5
    CPLD_CE_REG_REVISION : 0x34<rev:b>

    Do I need to load in a new version: the release note for loading the new logicloader is not clear. Can someone post clearly how to load in the new loader (step by step) plus which files - I get 5 files 3 elf, 1 upd and 1 raw.

    Thanks in advance for any help.

    Hello,

    Yes you will need to update to latest LogicLoader version which has support for the 5.7" display kit built in. This can be found at the following link:

    http://www.logicpd.com/do...oads/115/1002302.zip

    Unzip the files in the downloadable to a location on your computer.

    1) type 'load elf' at the losh prompt

    2) Go to "Send File" in TeraTerm

    3) Select the Lolo file entitled "1002302_lolo.elf"

    4) When it's done loading the file, type 'burn'

    5) Reset the kit

    Please post back to this thread if you have further questions regarding this.

    Once you have the updated LogicLoader (2.0.2 is the newest as of this post) you can use the 'video-open 1 16' command.

    If you need to check the available video modes, you can use the following:

    losh> help video-open

    Thanks,
