Hi!

I have to include a checksum calculation in the start of my program to 
verify the firmware integrity.

I verifyed that the IAR compiler, in the linker optios, has a tab to 
fill the unusued bytes and automatically calculate the Checksum 
(simple, CRC, etc).

My question is this:

Does some one has a sample code to use this automatic calculation?

I mean how to automatically find the __checksum label and the ranges 
of the calculation that the linker used to calculate the value stored 
in it?

Thnaks in advance for any tip.
