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 are.

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 also.

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.

Regards, Swapnil
