Field Upgrade of Microblaze Software

I am working on a project that uses a Spartan 3E. I have Flash, SRAM and Configuration EEPROM connected to the FPGA. I am running a bootloader (that copys the software from flash to sram) thats initialized in the BRAMs. I would like to have the abaility to do field upgrades of the Microblaze software in Flash and have the bootloader point to the correct image. I am going to have 2 images in the Fl;ash at anytime.

 

1. Factury Default Image

2. Current Image (eg. Version 2.1)

3.  Previous Image (before Field Upgrade: eg. Version 2.0)

 

Is there an app note showing how to do this? Thanks
