why PC can't recognize the demo board? I put already D+ up by jumper. it show ''unknown device'' in computer management.

The reasons are simple:
1.Programming the flash memory. 2.Your PC doesn't have drivers. 3.If you are using the Demo version from st then it was working properly. 4.Check the BOOT options, power supply to the board and Check the JP1 jumper settings for USB.2011-05-17 03:37 AM
The demonstation software was downloaded from ST website, I selected the power supply from USB port, it's work well, I think the power supply and BOOT option are correct, as well as flash memory. JP1 is ok, too. My PC must havn't driver because my PC can't recognize the new hardware. So my question is why my PC can't recognize the target board? It must install MSD card at first? I havn't install anything yet, just plug into USB port.
