MCU Load Issues

[Paul Van Dyke]

Went to load the latest update (to me) on my K3S and the radio is now
locked in the dark screen MCU LOAD mode. I have checked comports, they are
up to date, and rebooted twice and even shut the computer totally off.
Nothing ... No power from the P3 is coming in... plugged and repluged the
USB cables.    all steps that are in the MCU Manager have been followed...
even tried to do an EE INIT and it will not do that either...

Any ideas or I wait till Tuesday

Thank You

Paul,

Go to the K3 Utility Help file and find the instructions to "Force a
Firmware Download.

Follow those instructions and you should be back on the air.

That "problem" is usually caused by a computer glitch during a firmware
load to the K3S.

You may also have to throw the switch on the KIO3B Main board if you
only have the USB cable.
Very old boards did not have this switch, in that case you will need the
RS232 interface to the RJ-45 jack and set RS232 to 38400.
