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 jbe -- Pengutronix e.K. | Juergen Beisert | Linux Solutions for Science and Industry | Phone: +49-8766-939 228 | Vertretung Sued/Muenchen, Germany | Fax: +49-5121-206917-5555 | Amtsgericht Hildesheim, HRA 2686 | http://www.pengutronix.de/ | _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
