Software Update on STM8

Question asked by pradeep on Sep 12, 2012

I am working on a low density STM8S with 8Kbyte flash memory.
I need to accomodate a main software and a recovery software.
I do not need any special bootloader as I am planning to make
the software update as part of the application itself.

I am newbie in this.
Can someone tell me if the following strategy sounds good or
if it has any issues:

Divide the Flash memory into (Program memory + UBC region[user bootcode])
Program memory shall contain the main software.
UBC area shall contain the recovery software.
Recovery software shall be used in case a software update fails.

Any insights/comments will surely help me.

Thank you.
