nrf51 DK, could not write file, disk full error.

Hi, I just got my nrf51 DK, I compiled the BLE_URIBeacon example and downloaded the hex file, 361.2KB. I pushed the RESET button and connected the USB cable to my laptop. It shows a bootloader, as a MTP. When I try to paste the hex file, it shows error "Could not write file. Disk Full". When I looked at the properties of the MTP, it shows a total space of 128KB. The DK says mbed enabled, but how is this possible if the example code is more than the Bootloader size. It would appear that I'm missing something, please help. Thanks for help :)

Sorry for the stupid question, I though firmware update meant uploading code too :P. Directly connected the DK and uploaded the code successfully.

You hold the reset button and plug in the USB cable only when upgrading the bootloader. You will see a MBED LOADER disk in your drive portfolio.

For normal downloading of HEX files, plug in the USB without holding the reset button down. You will see a MBED disk in your drive portfolio. Download your HEX file. When finished, just hit the reset button.

Yeah, i realized it after an hour of asking the question :P. Thanks for replying though :)
