Hi,
Continuing with NAND problems...
I replaced:
#define CFG_LCRR (LCRR_DBYP | LCRR_CLKDIV_4)
by:
#define CFG_LCRR (LCRR_DBYP | LCRR_CLKDIV_8)
And now I can read and there is only one bad block, but no erase or write yet:
(I checked WP and its correct, 3.3V)
=> nand read.jffs2 0x02
Dont know if can be a hardware problem, cause NAND is found in localbus:
I just copy/paste nand_scan code (from nand_base.c) and try this:
With u-boot-1.1.4 + drivers from u-boot-1.3.4:
DDR RAM: 128 MB
FLASH: 16 MB
In:serial
Out: serial
Err: serial
NAND: 64 MiB
=> nand scan

When I had discovered that my NAND flash had all bad blocks, I found a
patch to dump the NAND blocks (which I think you had said you did). What
I found in my case was that on one board 8 data lines were disconnected
and on another one of the 0 ohm resistors was faulty (so one bit was
always read as
Now i got all NAND stuffs from u-boot-1.3.4, including common/cmd_nand.c
and drivers/mtd/nand/*, but still the same problem.
Other components of u-boot can influence NAND behavior?
I saw some people with similar problem using "nand scrub", but im little
bit afraid with this command...

Odds are that something is broken in the NAND driver, and you're reading
garbage.

Hi all,
Im trying to use my NAND flash at MPC8360E-RDK based board.
But it seems that the whole chip is bad blocked.
Dont know if Im missing something... below some outputs:
=> nand info
Device 0: NAND 64MiB 3,3V 8-bit, sector size 16 KiB
=> nand bad
4000
