Hi all,
Currently I'm trying to load a barebox environment image from NAND
storage but can't load it correctly.

I have given the path of my environment in the config :

CONFIG_CONSOLE_FULL=y
CONFIG_CONSOLE_ACTIVATE_FIRST=y
# CONFIG_OF_FLAT_TREE is not set
CONFIG_PARTITION=y
CONFIG_DEFAULT_ENVIRONMENT=y
CONFIG_DEFAULT_ENVIRONMENT_PATH="arch/arm/boards/cartesio-evb2065/env/bin"

After registering the NAND device I prepared a couple of Bad Block
aware partitions :

devfs_add_partition("nand0", 0x00000, 0x200000, PARTITION_FIXED, "self_raw");
dev_add_bb_dev("self_raw", "self0");
devfs_add_partition("nand0", 0x200000, 0x200000, PARTITION_FIXED, "env_raw");
dev_add_bb_dev("env_raw", "env0");

On compilation I get a barebox environment image - barebox_default_env.
Flashed this image to the env0 partition via DFU -
dfu -V 1 -P 24 /dev/env0

From host sent the barebox_default_env (the default_env file is page
alinged) via DFU to the NAND.

The flashing worked fine.

But now when I re-boot the system :

barebox 2010.09.0-00003-ge5727b1-dirty (Sep 27 2010 - 17:18:50)

Board: STMicroelectronics EVB2065 with Cartesio Plus
NAND device: Manufacturer ID: 0x2c, Chip ID: 0x48 (Micron NAND 2GiB 3,3V 8-bit)
Scanning device for bad blocks
Malloc space: 0x00860000 -> 0x00e60000 (size  6 MB)
Stack space : 0x00850000 -> 0x00858000 (size 32 kB)

This system is stuck at this point. Investigating further - I see that
we are stuck at
in the common/environment.c
int envfs_load(char *filename, char *dir)
{
...
buf = xmalloc(size);
buf_free = buf;
ret = read(envfd, buf, size); - Stuck here

I'm wondering why this read is failing. Could the developers shed some
light on this ?

Regards
Gaurav
