Remote firmware upgrade

Started by Sandeep_Mbedded February 18, 2009
hi all... I am Sandeep.M...
I am trying to implement remote firmware upgrade feature to my rabbit
3000, RCM 3200 based system...
I would like to accomplish this without the use of RabbitLink board.
So if anyone has tried this out, please help me with necessary 
information regarding how to start with this project...

Thanks...

Here is a solution http://www.shdesigns.org/rabbit/SHD-DLM.shtml However, the only guaranteed safe way to do remote upgrade is to have some external memory such as some serial flash attached to your rabbit. Download the new code to the serial flash, checksum it and then boot to a small program that can copy the downloaded code to the program flash and then restart the rabbit.
