FRDM-K64F - Getting started: Downloading programs seems to fail

Hi, I'm getting started with the FRDM-K64F and have some issues trying it out.

In the mbed compiler everything seems fine. I downloaded the hello world example (mbed_blinky_K64F.bin) and sent it using Tera Term (File -> Send file...) and the LEDs are blinking (seems to be writing the data).

I then click the reset button on the board but nothing happens. I would expect the LED to be blinking. I have tried other binaries as well (that should send output on the terminal, but that doesn't work either).

Details: Version: 0221 (FRDM-K64F) I'm on Windows 7 64 bit. I have installed Tera Term (4.8.4 since 4.8.5 crashes during installation).

If I could get a pointer in the right direction that would be awesome!

If you plug in your K64F and did a firmware update to the mbed firmware (if not, do it ;) ), it should appear as a USB drive. Drop the downloaded bin file on there, and then reset your target.

That worked! I don't understand why my other method didn't work though...

Because that is a completely different thing, that sends the data of the bin file overr the serial port. Which while moved to the MCU, is not used to program it.
