I'm not quite sure what you did! If the "copy new files" check box is checked, then the K3 Utility will do an FTP step and copy files from Elecraft's FTP server to your firmware folder. First. Before it tries to send firmware to the K3. Then the "most recent" firmware files in the firmware folder are sent to the K3.
These aren't concurrent operations. Could you expand on your sentence "The Utility was directed by the user to move certain firmware files to the K3 and the configuration of the Utility interface was not concordiant with the version of the firmware files." I'm not quite sure what you mean there! I'd like to get this right if it can be made better so that no one else stumbles on this.

The issue is not any of the following: 1. Firmware version 2. Utility version 3. Cable, serial port, or communication over RS-232. The issue is this: In a nutshell, user error. But the user (me in this case!) was un-aware of the rules to follow: The Utility was directed by the user to move certain firmware files to the K3 and the configuration of the Utility interface was not concordiant with the version of the firmware files. In short, I did not realize I had left the check-box checked above the button "Check new version". After a few attempts, I was able to make the Utility load without error. It was nervous for me because being firmware, seeing errors on the load raised the hair on the back of my neck because things like that can often render the platform a brick. I knew in the back of my mind that Wayne and Lyle had made the process robust and enough bootstrap code should/would be on the K3 to bring up the executable on the K3 to handle a new MCU DL. In the documentation there are two methods described for resetting the K3 if the MCU load fails: 1 a) pull the power b) Hold the POWER button and wait about 10 seconds then go to step 3. 2 a) pull the power b) HOLD HI/LO while TAP POWER and wait about 2 seconds then go to step3 3 a) Re try loading the MCU - starting the Utility, re-confirming communication to the K3, and then choosing the firmware, etc.. The resynchronization error is a loading error by the Utility getting in the weeds because of the aforementioned configuration of the firmware data and the Utility settings (AFAIK). I've been trying to think of the use-case for what caused it, but it becomes nebulous because I don't know enough about the protocol used by the Utility and the meaning of the data in the S-code files. A block diagram of how the Utility works would be great. How it parses the first file, and etc. Why was it so difficult to get the MCU load to work after the Re-synch error? Method #1 did not work for me to re-try the MCU load. I was only able to get the K3 to succeed in testing the Serial port after a failed MCU load if I used method #2 to re-start the K3. The good news is that I was able to reload the MCU w/o Resync errors, but it was that moment of "uhh oh", you know what I mean? If I could make a suggestion to the documentation team about this: The documentation of the error messages in the Utility doesn't seem to cover this error. I searched the Help file on the Utility. There also could be a little more treatment in the K3 manual over loading MCU and fool proof steps for loading in these use cases: 1. Upgrading to a newer MCU 2. Downgrading to an older MCU And, for the support team, I'd suggest putting much more online with respect to past versions of the MCU. 2.57 isn't _that_ old, right? It's not on the web site in a downloadable form, unless you know the secret URL. All is well that ends well. -jeff _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list. Subscriber Info (Addr.
