Early versions of P3 firmware required that the P3 be turned off for all K3 firmware installation. The K3 Utility determines the P3 firmware version, and it displays a P3 firmware version dependent warning dialog if needed.
However if the K3's firmware load is interrupted, and the K3 powers up into its boot loader (MCU LD on the LCD when you apply power), you'll need to follow the instructions in K3 Utility Help, Troubleshooting, MCU Load Failure. In that circumstance, the P3 must start and stay off when the K3 is powered on until the K3 firmware is reloaded. The problem is that P3 initialization issues K3 commands (from the K3 Programmer's Reference) that can't be interpreted by the K3's bootstrap loader, and they put the bootstrap loader into a state that cannot be recovered without power cycling the K3. microHAM's router software does the same thing. This is why both microHAM and Elecraft recommend not loading firmware through port sharing software that multiplexes the K3 serial port. It works some of the time, but not all of the time. The K3 requires firmware to behave as its programmer's reference describes. 73 de Dick, K6KR -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Lee Buller Sent: Monday, May 28, 2012 7:51 AM To: Elecraft Reflector Subject: [Elecraft] Information on K3/P3 Utility Just got my new P3 working on my K3. Several years ago, there was an issue of updating the K3 with the P3 connected. Is that still true? What is the procedure for update either devices? I have the latest P3 and K3 utilities loaded and they talk to each device while all is connected for use. Thank you Lee - K0WA In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense. Is Common Sense divine? Common Sense is the image of the Creator expressing revealed truth in my mind. - John W.
