Hi everyone

I am working with TM4C123gh6pm and would like to build remote firmware upgrade feature.I want to write to application code on my flash e.g. Application 1 will reside between 0x00000000 to 0x00001FFFF and the Application 2 will reside between 0x00020000 to 0x0003FFFF.I want to switch between these two application while booting  according to my need.

I am having no idea how to do that as I am new to this series of microcontroller.Please help me with this.

 

With regards

Arun

    Hi Arun,

         There is a Tivaware Boot Loader User's Guide that you can review. You, can also do a search in the forum for similar post.

    Hi Arun,

         I think it will help if you review how these two example programs work together, boot_serial and boot_demo1. The boot_serial is the bootloader used for updating the application using uart. The boot_demo1 is the application program.

        The boot_serial and boot_demo1 example program is not present at my copy of Tivaware for Tiva Launchpad. It is present at my Tivaware for LM4F232 kit.
