Version 1.2.6 of LogicLoader does not have standard support for the 5.7" display kit and Logic will not be adding this functionality. Development for LogicLoader on the 9520 ended before the 5.7 display kit was released. However it should be possible to get this display up and running by using the 'w' and 'x' commands to write and read lcd registers on the 9520. You can then use the 'source' command to execute a series of commands from a file stored on the CF card. For an in depth explanation of these commands please refer to the LogicLoader User's Manual.
