Su,</P><P>&nbsp;&nbsp;&nbsp;&nbsp; Could you tell us what the LPC chip you are using? Please give use the chip part number.</P><P>&nbsp;&nbsp;&nbsp; When you test on the same EVB board, did you solid it on the chip? Or use some socket?</P><P>&nbsp;&nbsp;&nbsp; Please check the pin connection,&nbsp; whether it has the pin bad connection problem, your problem is caused by the hardware.</P><P></P><P></P><P></P><P><BR />Have a great day,<BR />Kerry</P><P></P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
