I am quite confused about partitions in my NAND flash.
Linux can mount my rootfs, so partitions make sense to the kernel, but
from the shell fw_printenv can't read the uboot environment, not matter
what I use in /etc/fw_env.config.
uboot is reading the proper uboot env, and booting the system.

I am trying to move from uboot-1.3.6 to uboot 2013.01, where the old
works, the new prints this before freezing:

something from those patches is lost in the current uboot.
What can I try next.
Bellow are the patches I applied so far.
boards.cfg: add target name
at91sam9g20ek_2mmc_nandflash,at91sam9g20ek_2mmc_dataflash_cs0,at91sam9g20ek_2mmc_dataflash_cs1

Using uboot 2013.01, booting from NAND, I am having difficulty
understanding how partitions (areas of NAND) work.
I have written to NAND in the following layout:
0x000 at91bootstrap1
0x002 uboot1
0x006 uboot-env1
0x020 kernel1
0x040 rootfs1
0x800 at91bootstrap2
0x802 ub
I am finally on uboot-2013.01.
I having issue using: env import
I have at91bootstrap reading an uboot environment from an address
location in NAND to RAM address 0x2000.
The environment uboot is compiled to load by default has one set of
variables, but the environment loaded into ram by at91

Is it possible to have uboot read it's environment from a RAM address,
rather than NAND?
OR
Can uboot's scripting support load variables from a RAM address?
My NAND layout has redundant halves:
0
uboot
ubootenv
kernel
fs
128
uboot
ubootenv
kernel
fs
256

I have an embedded project using an atmel arm processor, primary
bootloader at91BootStrap on NOR to call uboot (and the reset of the
system) on NAND.
I am trying to devise a way to partition NAND redundantly, with 2 copies
of (uboot + uboot-env + kernel + roofs).
At91bootstrap will have to decide
How does uboot decide where in NAND the configuration will be found?
I'm getting the classic errors:
*** Warning - bad CRC or NAND, using default environment
I am writing my environment to nand, with crc, but how do I know that
uboot is looking for it in the right place?
Is that a compile time on

Is it possible to add my kernel to the rootfs partition rather than have
a separate partition?
I am using U-Boot 1.3.4, on a at91sam9g20ek (256Mb Nand, 8Mb Nor), and
use the sam-ba firmware upload tool.
I'd like to put everything on nand, ignore nor, and hold redundant
areas, in perpetration fo

Maybe partition is
What area of memory is the crc stored for a partition?
I would like to find some detailed documentation on the crc (how big is
it, where it is stored, how to invalidate to force the booting from a
second area).
