John,

I just starting using my FRDM-K64F today and I upgraded the firmware to the same version you did. I don't see any console activity unless I explicitly write to the serial port from my program. Here's a simple test program that blinks an LED and writes Off/On messages to the serial port:

Blink the LED and send console messages

#include "mbed.h"

Serial pc(USBTX, USBRX);
DigitalOut myled(LED1);

int main() {
    while(1) {
        pc.printf("Off\n");
        myled = 1;
        wait(3.0);
        pc.printf("On\n");
        myled = 0;
        wait(1.0);
    }
