These problems have gone and I did finally get the u-boot.bin on version 
2009.06. I'm porting u-boot to a self-made board over AT91RM9200. There 
are some further small problems with the operation on NOR flash, whose 
model is INTEL 28F640J3.

I copied flash.c from board/xm250/ and made modifications to suit my own 
board because xm250 uses the same flash chip. I followed the steps that: 
burning loader.bin-> u-boot.bin -> entering u-boot prompt -> downloading 
and copying boot.bin to address 0x10000000 -> downloading and copying 
u-boot.gz to address 0x10010000, then set BMS to low and reset the 
board......smooth process except the following info:

1)existed at the startup of u-boot:

Program downloaded successfully

Jump to Application!


U-Boot 2009.06 (Jun 30 2009 - 14:35:56)

DRAM:  32 MB
Flash lock bit operation timed out
Flash lock bit operation failed at 10000000, CSR=EA000006
Flash lock bit operation failed at 10060000, CSR=FFFFFFFF
Flash:  8 MB
*** Warning - bad CRC, using default environment


2)existed when running "protect" command:

U-Boot> protect off 10020000 1009ffff
Flash lock bit operation failed at 10020000, CSR=FFFFFFFF
..Flash lock bit operation failed at 10040000, CSR=FFFFFFFF
..Flash lock bit operation failed at 10060000, CSR=FFFFFFFF
..Flash lock bit operation failed at 10080000, CSR=FFFFFFFF
.. done
Un-Protected 4 sectors


All seem to be timed out operations.....any idea please?

Johnson Yu
