The extract\_flash.c program comes with the latest release of Dynamic C 9.62A which you can download from Digi’s website; [https://www.digi.com/support/productdetail?pid=5053&amp;type=software](https://www.digi.com/support/productdetail?pid=5053&amp;type=software)

It will allow you to do the following;  
A program you can compile to RAM on Rabbit hardware in order to dump a copy  
of the firmware stored on the flash. You can use the Rabbit Field Utility  
(RFU) to install the firmware on a new board after converting the Base64  
dump to a binary file
