Consider the bad blocks in your NAND. So, you will need a bad block aware
device to write to.
This code in your board specific init routine should add the thing:
[...]
/* ----------- add some vital partitions -------- */
devfs_add_partition("nand0", 0x00000, 0x40000, PARTITION_FIXED, "self_raw");
dev_add_bb_dev("self_raw", "self0");
devfs_add_partition("nand0", 0x40000, 0x20000, PARTITION_FIXED, "env_raw");
dev_add_bb_dev("env_raw", "env0");
[...]
(Sizes depending on the size of your boot loader binary).
And at runtime:
barebox> addpart /dev/nand0 256k(barebox)ro,128k(bareboxenv)
barebox> erase /dev/nand0.barebox.bb
barebox> tftp barebox.bin /dev/nand0.barebox.bb
