Validation app fails to run on Giga R1

[rbultman]

After compiling and downloading the KVStoreValidation example, the board blinks the "SOS" pattern on the red LED indefinitely. In order to reflash the board, hold down the BOOT button, press and release the RESET button, release the BOOT button - need to use the desktop client to do this as the cloud interface can't see the board anymore.

Steps to reproduce:

1. Connect board to computer (Macbook Pro) using USB cable and cloud agent running.
2. Open the Arduino web interface.
3. Select the KVStoreValidation sample application.
4. Ensure that the Giga R1 board shows as connected in the web interface via USB.
5. Compile and download the example.
6. After a few seconds, the board flashes the SOS pattern on the red LED.
7. No messages print in the monitor. "Cannot initialize kvstore" DOES NOT appear on the monitor.

This also happens with the desktop client.

Additional note: I added a print statement and delay just prior to the call to kvstore.begin. This message prints and then the SOS pattern appears on the red LED.
