[Elecraft] {K3} New Upload of MCU stuck

[Keith Heimbold]

No problem. 

I tried uploading the firmware update through the virtual port created by uRouter program from MicroHam. This is a major "no no". I followed the instructions as per Fred's manual that I needed to follow the bootstrap procedure for failed upload and found out that I needed a direct not virtual com port to do the upload and that using a virtual port will result in the issue of the upload locking up.

I used a serial to serial connector after removing all connectors and followed the procedure cited in the help portion under troubleshooting and voila the firmware uploaded and alles en ordnung.

Hope this helps. I was a bit excited when I was able to get the answer by reading cady's manual and I wanted to give Fred some props for his very thorough and helpful book on the K3.
