This could be an intermittent communication problem. I'd look first at the serial port and USB to Serial adapter (if there is one).
When the part wears out, my experience is that it continues to fail at the same address. My K3 S/N 00018 has had more firmware installs than anyone's with the exception of N6KR. Mine is still on its first MCU and FPF. 73 de Dick, K6KR -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Bob Sent: Wednesday, May 11, 2016 14:03 To: Elecraft <Elecraft@mailman.qth.net> Subject: [Elecraft] Interesting FW Upload issue with K3 (happy ending) Hi: I am curious if this is an indication of a programmable part wear out, or perhaps simply a timing issue between my K3 and computer. I was installing the 5.38 firmware update today in anticipation of installing the two new synthesizer hardware upgrades. The K3 utility found the latest software, connected without issue, and proceeded to do the MCU update to 5.38. However when it came time to the Front Panel Firmware, it failed, complaining that a retry count had been exceeded. The remainder of the update went just fine, with both of my existing synthesizers being successfully updated. The good news is that a retry of the update (Send All Firmware to K3) worked the second time around, but it still remarked on one retry being required. I have copied the log data that shows the problem, and again wonder if this was just bad luck, or an indication that the programmable part on my FPF is wearing out: K3 responded with revision 05.38 16:23:43 MCU firmware load is complete 16:23:43 Elecraft K3 Utility Revision 1.13.5.9 16:23:43 OS Version 6.2 Build 9200 16:23:43 K3 MCU revision 05.38.
