I am using the OM13027: LPC4330-Xplorer Board,which I can found that it is flashless and use the external flash S25FL032P0XMFI013. I download some example project from nxp websit and generate the binary files. After I program the external flash and turn off the power, when I repower the board the lpc4330 can not boot from the spifi flash. I had set the boot mode right but I don't know why it can't still boot from external flash.
