Hi!

I have an LPC1788 board with 128Mbyte NAND flash, 32Mbyte SDRAM and other peripherals.
I followed the instructions on http://www.lpcware.com/content/project/lpc177x8x-u-boot-port/u-boot-build-procedure
but the result the usart is unreadable when the u-boot is relocated the RAM.
I download the nxp compiled u-boot-lpc.hex and the result is same:

I wrote a memtest before relocate and the memories works fine.
I have no idea whats the problem.
