No, this is a another bad block table. [1] You need to generate the bbt. Factories only marks block as bad(with an mark pattern). > I'm using the barebox 2013.05.1 stable release from git > You can "try" to generate a bbt when you generate a nand bad block aware device, nand command "nand -a", then run "nandtest -t -m /dev/nand#.bb" to fill this bbt with "current" badblocks. I don't know if this generates a bbt for you. But give it a try, I think it should do :/ [1] http://www.linux-mtd.infradead.org/tech/mtdnand/x144.html _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
