I have read the MCU load error under K3 Firmware Self-Test and what to
do in an error of loading MCU but I have lost communications with the k3
with my serial to usb cable that I normally use and have tried a serial
to serial cable to another computer that still has a serial port- DB9
connections, I have also changed the baud rate to 38400 which it was
before it crashed. No luck with any of these actions. Any help would
be great.
John
