TMS320F280049C: Toggle boot between Flash0 & Flash1

Phil Gillaspy

My company wants our software running in Flash bank 0 to load a new image into Flash Bank 1, then reset processor and boot and run image in Flash Bank 1. Note that the new image in Flash Bank1 is just a rebuild of the image in Flash Bank 0 but with a few code changes. Are there any ideas on how that might be accomplished?

you need to have a small piece of code to decide which image to execute and jump to that.

this code can be kept in a sector 0 of flash bank 0 and not erased anytime in the future.

you can see that a similar strategy is used in this app note - www.ti.com/.../spruiu9
