| # Overview | ||
| ## Overview | ||
|
|
||
| *missing* | ||
| 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. | ||

||
| ## 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](https://launchpad.net/gcc-arm-embedded) | ||
| 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) | ||
