Is there a way to let the LPCxpresso linker add some kind of checksum for the whole Flash image? I am not talking about the vector table checksum. I tried using --build-id option on the linker but it does not seem to do anything. I need some way to be able to check what flash image I am dealing with.

It takes less then 15 minutes to write one's favorite checksum program in C - close to what you already spent on asking the question and you will spend on checking the responses.

A good tool for making checksums is the SRecord Tools available from srecord.sourceforge.net. The SRecord Tools can process and convert many types of input files (such as .hex, .bin, etc.) and generate or insert checksums. The tools are smart so you can have them only checksum a certain address range, or split a .hex file up and generate several .bin files if you want. There are command-line versions available for Windows.

I will take a look at the srecord tool. I should be able to add that as a post processor to my build... Thanks again.

To GBM:
So why haven't they done it at Code Red if it is that easy? There are a thousand easy things I can do myself, but a thousand times 15 minutes is wasting a lot of my time, especially if someone else has already done it....
