On reset of LPCExpresso 122x (using LPC1227 module), if the ROM bootloader using UART0 is invoked,  does the bootloader code set the IOCONFIG  for PIO0_1 to be RXD0 and PIO0_2 to be TXD0?   Is there a way to change this without changing the bootloader code itself to use the alternate PIO2_1 (RXD0) and PIO2_2 (TXD0) pins for UART0?   Just started on using th LPC1227 module, so any input is appreciated.

You're right :) If you want different UART0 pins for ROM bootloader you've to ask NXP for your own LPC122x edition :cool:
