If you are just starting out, try downloading the "Hello World" program binary to your microcontroller to test things are working. Save it to your mbed Microcontroller Disk, and then hit the reset button to run it. For more things to try, see the mbed Handbook "Getting Started" guides.
The mbed NXP LPC2368 is our beta board, and will remain fully supported. The new LPC1768 based board is now available to order!
