Bootloader for coldfire 52235 with an external flash memory

[fjoli]

Hello,

I'm trying to make a bootloader for the coldfire 52235 with an external flash memory.
I succeed in programing the external flash memory with a binary file, now I would like to make a bootloader which check in the flash memory if there is a new application to load and then load this new application to the internal memory of the coldfire.

I don't really know how can I have a bootloader in the beginnig of the internal flash and the application in the other part of the internal flash memory.
Do I need to have two differents projects and how can I make the link between the two projects?

Could somebody help me about this or show me some exemple ?

For information : I use the IDE CodeWarrior 7.0

Regards

Fabien

Hi

There are some details about doing this in the following documents:
http://www.utasker.com/docs/uTasker/uTaskerBoot_003.PDF
http://www.utasker.com/docs/uTasker/BM-Booloader_for_M5223X.PDF
The second is very specific to the M52235 and CodeWarrior, including programming guide and linking details.
