Hi Wolfgang Denk,

I have a custom board with Processor is Samsung 2412 , Arm926EJ-S. ( My
board has 64MB mobile SDRAM , 32MB Nand Flash. Serial Port, and USB ) no
other devices as of now.

I have received a u-boot source 1.1.4 from Samsung FAE. With added files for
SMDK2412 board. I have compiled and produced a u-boot.bin . And loaded this
file into the NAND flash using JTAG.

On power on i see the u-boot prompt. on minicom. The problem i'm facing now

1. address 0x3000_0000, 0x3100_0000, 0x3200_0000 ,0x3300_0000 pointing to
same memory. a Write in 3000_0000 is duplicated in the other 3 locations

2. I use "loadb" command to transfer a  bin file. but if i try to write the
file to Nand Flash using "nand write" command I get error. and Board hangs.

I have contacted Samsung FAE. but not got any technical support on this
issue till now.
