Hi there,
I have an LPC1788 with an own bootloader and an application. Is it possible to exchange RAM data between both? The board also have an external RAM.
Physically this should be possible, since there is no power-down between the jump from the bootloader to the application. But I suppose the RAM is cleared, when the stack/heap are initiated.

Looking at the startup code should clear that up for you. Alter the memory arena the two use, and they won't interfere, Store data you want to pass in a location known by both.
Ok. Thanks for the help, guys. I'll look at this asap.
