Overview
mbed LPC1768 is a small development board by ARM. A LPC1768, an Ethernet PHY transceiver (DP83848J), a 2MB flash device (AT45DB161D) and a MBED-IF01 (LPC2148) are present on the board. This board aims to make it very easy to flash a new firmware. There is no need for an external programmer. The sole purpose of the MBED-IF01 is to appear as a USB flash drive when the board is connected over USB to a computer. The most recent binary file stored on the USB drive is flashed on the next reset.
See here for more information about the board.

Using UART
This board opens a serial interface through the USB automatically.
Supported Toolchains
For using the mbed LPC1768 board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
Flashing the device
The easiest way to flash the device is to connect to the board via USB. The
board appears as a 2MB usb drive. make flash will copy your binary file to
the root directory but you need to manually reset your board by pressing the
reset button.
While the LPC1768 is flashed by the MBED-IF01 with the new firmware, the
status LED blinks fast.
Known Issues
- Does not compile with the mentor graphics toolchain (compare https://github.com/RIOT-OS/RIOT/issues/751)
