CRC generator for hex file

Hello,

I am looking for a way to generate a CRC after compilation and add it to the hex file at a specified address so that it can altogether be programmed to flash and at runtime can be compared to a value calculate by the program.

Any idea how to do it, best in an automated way, so that I don't have to fiddle in some value somewhere for every compiler run? I use Atollic True Studio Light and asked something similar there too. uC is STM32L151

Thanks

Martin

Here we've just written small apps to read in .BIN, .HEX or .ELF/AXF type files and process and package firmwares, adding CRC or checksumming as required. Often had to do similar things for legacy hardware using old DOS apps and batch files, folding the process into a single step. The old Motorola and Intel HEX formats aren't inherently complex.

Thanks for your answers

Jan, I will take a look at SRecord.

Clive, I wonder if you want to make me look forward to you publishing these apps or if you want to encourage me to write my own apps. I'ld welcome if you published yours. 🙂

I think they are of relatively low complexity, I'd publish but generally find doing so to be unrewarding.
