    Is it possible to have LOLO load a java application?
    IBM makes a JVM that runs on small devices and on ARM processors among others.
    It should be possible to have the LOLO boot script launch the JVM right?
    How would I get this JVM in the app in the flash?

    Did anyone have success running a java application on the LH7A400-10 ?

    Patrice,

    In general, LoLo can load _any_ type of application. The LogicLoader will load raw binary files, elf-formatted binary files, Motorola S-record files, and Microsoft *.bin files. What is actually in those files doesn't matter to LoLo. It just needs to know where to store them and the starting address of the application so it can jump to it.

    As to your Java question, I don't really know. I guess it all depends on what the IBM JVM needs to run. Most of the time, a JVM uses the services provided by an underlying operating system to run. If the one that IBM has available doesn't need an OS, then you'll just have to figure out what it does need in terms of timers, thread management, etc. in order to properly run a Java application. Then, you'll need to figure out how to package that supporting software, the JVM, and your Java application together into one runnable package.

    Best of luck and keep us posted on your progress,
