Date: Thu, 5 Jul 2007 11:51:46 +0800 From: <sasin@...omon-systech.com> To: <linux-kernel@...r.kernel.org> Subject: CRAMFS support for 4KB page NAND FLASH Trying to boot off CRAMFS on a 4KB page NAND FLASH (new device), I ran into the "wrong magic" issue. MTD's nand_read (drivers/mtd/nand/nand_base.c) is returning the right data. cramfs_fill_supper calls cramfs_read (fs/cramfs/inode.c) which reads 4 pages and the 1st page of data gets corrupted. If I set BLKS_PER_BUF_SHIFT in this file to 0 instead of 2, so that only 1 page is read, the data is uncorrupted and the magic value matches but it crashes later (comments say that this values should be 2 or higher, so this is not surprising). So are 4KB-page devices supported by CRAMFS? I'm using linux 2.6.20.1 for ARM. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
