We have a new board that we have designed based around the LPC4350.  We are booting from external 32 bit Static Flash memory.  The board works perfectly every time when debugging through the IAR EWARM along with a Segger J-Trace J-Tag module.  With the J-Trace removed, the board boots normally when first powered and works fine most all the time.  Once the board is running, if you simply ground the Reset input to the LPC4350, it will never reset and start running from the external flash like it does on the initial power up.  Any ideas on what would cause this?
