[root@localhost ] vim arch/arm/plats3c24xx/static struct mtd_partition smdk_default_nand_part[] = { [0] = { .name = Boot, .size = SZ_128K, .offset = 0, }, [1] = { .name = param, .offset = MTDPART_OFS_APPEND, .size = SZ_1M SZ_128K, }, [2] = { .name = kernel, .offset = SZ_1M, .size = SZ_1M * 3, }, [3] = { .name = root, .offset = MTDPART_OFS_APPEND, .size = SZ_2M * 10, },/* , [5] = { .name = S3C2410 flash partition 5, .offset = SZ_1M * 14, .size = SZ_1M * 10, }, [6] = { .name = S3C2410 flash partition 6, .offset = SZ_1M * 24, .size = SZ_1M * 24, }, [7] = { .name = S3C2410 flash partition 7, .offset = SZ_1M * 48, .size = SZ_16M, }*/}。3. 去掉nand flash 的ECC[root@localhost ] vim drivers/mtd/nand/打開drivers/mtd/nand/搜索關(guān)鍵字NAND_ECC_SOFT，在s3c2410_nand_init_chip函數(shù)里修改NAND_ECC_SOFT為NAND_ECC_NONE4. 支持啟動時掛載devfs為了我們的內(nèi)核支持devfs以及在啟動時并在/sbin/init運行之前能自動掛載/dev為devfs文件系統(tǒng)。[root@localhost ] vi fs/Kconfig
