Hi Alan, I had a K3 load lockup a few weeks ago and I used the technique described in the help menu in the K3 Utility Program. Search for MCU Boot Loader Troubleshooting. Full instructions will be displayed.
I also removed the RS232 link between the K3 and P3 so that the K3 had a direct serial connection to the computer. But that may be overkill. I know what caused my particular lockup. I tried to cancel a load sequence after it began because of a stupid impulse. I know I'll continue to do stupid things but I won't do that particular stupid thing again. 73, Mike K2MK Alan Grant wrote > > I don't know what I have done to my K3, no 5779 I was trying to update the > Beta 4.51 and the computer just filled through all the attempts to connect > on different ports at different baud rates, and could not connect, next > thing I know, the transmit light just keeps on flashing the dial lights > went out and I can see mcu ld faintly I cannot turn the > > K3 off with its power switch I think I nearly had a heart attack.
