Dual Images best practices

Nishant Garg
Intellectual 3000 points

Hello,

Is there any documentation regarding best practices and steps to implement dual images using the boot loader in ROM of our devices? Is it as simple as compiling a project for two different flash locations, and using the default bootloader to load these images to their respective areas of flash? Or do specific considerations need to be made for the vector table or a custom bootloader at the beginning of flash?

Looking for the basics steps here, I don't think it's too difficult, but want to make sure I'm not over simplifying it. If there is an app note or documentation that describes the process that would be perfect.

Thanks,

Nishant

    Hello Nishant,

    I'm sorry I can't help you much.  The ROM boot loader only deals with one application at address 0.  It has no ability to deal with dual application images.  Supporting dual apps on TM4C123x devices is challenging because there is no MMU and no way to swap the two halves of flash.  We don't have any examples or app notes for this.

    Regards,
