We received ours a week ago.

Unfortunately we had problems with it from the start and, before we could characterise the issue, the board stopped working altogether.

Now it only boots properly when the ERASE jumper is closed. When the ERASE jumper is open, we see 2 volts on VDDCORE (which is out of spec.), the crystal isn't oscillating and the JTAG TAP controller isn't working.

Of course with the ERASE jumper closed, we cannot do anything with it other than watch the boot loader ROM running.

There has a MP3 programmer run on SAM3U-EK which could play .wav and .mp3 audio file.
The programmer base on a free OS called Coos,it is similarity to RTX and UCOS.

You can get the source file of MP3 programmer from http://www.coocox.org/EXAMPLE/SAM3U_MP3_CoOS.htm
An RTOS specially for Cortex-M3----> http://www.coocox.org
