Hello,
Is there a way to load multiple programs at once from uVision onto a STM32?
I'd like to be able to have a bootloader program running that can jump into other programs that are already loaded into flash.
Ideally I would do this loading myself, but I've had trouble figuring out what exactly this requires. My idea was to turn on all the position independence options in the compiler/linker and then put the program wherever I wanted. However, I'm getting bogged down in figuring out exactly what it means to "put" a program somewhere. Do I need to parse the .hex and only load the sections that go in ROM? Can I put the program that goes in ROM anywhere as long as it's contiguous?
It seems like once the program is loaded you can just jump to the base + 4 and it will set itself up. But I'm having trouble finding good documentation about this.
If anyone has successfully created a bootloader and loaded applications into flash and then jumped to the loaded applications, I would be VERY interested in knowing how you accomplished this!
Thanks for any help you can provide.
