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 ?
