Hi,

I need to dump entire NOR memory (uboot+boot parameters+kernel image+ filesystem) of my BF548 based board into a file to clone board.

Mike some time ago suggests to me to use /dev/mtd* devices from user space.

now, my dmesg reports to me that there are 3 partitions in NOR:

Driver 'sd' needs updating - please use bus_type methods

physmap platform flash device: 02000000 at 20000000

physmap-flash.0: Found 1 x16 devices at 0x0 in 16-bit bank

Intel/Sharp Extended Query Table at 0x010A

Using buffer write method

Using auto-unlock on power-up/resume

cfi_cmdset_0001: Erase suspend on write enabled

RedBoot partition parsing not available

Using physmap partition information

Creating 3 MTD partitions on "physmap-flash.0":

0x00000000-0x00040000 : "bootloader(nor)"

0x00040000-0x00440000 : "linux kernel(nor)"

0x00440000-0x01000000 : "file system(nor)"

bf5xx-nand bf5xx-nand.0: page_size=256, data_width=8, wr_dly=3, rd_dly=3

How can I do a whole NOR memory dump, into a single and contiguous file?

Tanks a lot.

Massimo.
