Thanks, Bob. But I didn't detect the corrupt file problem until after the K3 Utility had started to load the MCU. I still think I might need to pass the file twice, once to verify that it's complete and checksums correctly, and then again to actually load the firmware into the radio.

This format contains a built in integrity check, namely a checksum for every line. So it seems the uploader did indeed perform an integrity check - and detected a problem. Relax, these guys *do* know what they are doing! For years, at work, I've been using this format for deployment of firmware images used to update products in the field, it's plenty robust, nothing else is required, insofar as verifying the file read in from disk.

There's a thing called MD5 that's very good for this... _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
