place and execute program in user defined memory block

[mmentink]

Hello guys,

I'm trying to implement a wireless system, that needs to be upgraded wireless.

For that, I came up with this solution:

A kind of "bootloader" connects with the server and downloads a user program. After downloading the program, it places the code (C code) on a specific memory position, to where it jumps and executes.

For this, I need to be able to tell the compiler that the code should be executed (and formatted) from a certain position.

C does have Malloc and Calloc, and things like Long jump, but how do I use that to place functions in a certain memory block??

I'm programming using CCS PCW 3.160 for a Pic18F252

Any help would be greatly appreciated.

greets,

Matthijs

Search the forum for bootloader and #org

And just add, that 'Malloc, and Calloc', have nothing to do with program memory allocation. They are data memory allocation commands...

On a pic, data and program memory space are separate. Program memory cannot be run from data memory.
