    Hi All

    What we are doing now:

    Up until now our development cycle has involved building our app to load into RAM, and then using LOSH to load and execute it. After the load operation, still via the LOSH prompt, we do a couple of remaps to turn on all of the RAM, flush the cache and tlb just for good measure and then do a jump to the start of our application. Once inside our app we completely hijack the interrupt vectors so that only our code is executing.

    What we would like to do:

    Be able to load our application into flash, so that we survive power cycles.
    Still, if possible, make use of the BOLO setup of the system (memory configuration etc). Make use of equivalents of the remap and flush functions we get via LOSH.

    Can anyone recommend the path of least pain? Is there any recommended reading for getting an app up and running out of flash with the SDK?

    Many thanks
    Colin

    You will be able to use a boot script to execute all of the commands that you are currently executing from the command prompt when you use your ram image. You will be able to burn your flash image with LogicLoader. Later this week we will be posting a new sample application that will run from flash. It is a simple application that copies itself from flash into sdram and then jumps to sdram and blinks an led. You should be able to convert your current ram application to flash without much trouble.
