Linux2.6.34.2在TQ6410上的移植详解(4)

在这要说明的：1.                    在./driver/mtd/nand目录下是关于nand的驱动，与硬件相关的文件是s3c2410.c。如果使用其他的硬件的话可以替换此文件。2.                    ./driver/mtd/nand/s3c2410.c中的s3c2410_nand_driver的.driver中的name字段一定要与./arch/arm/plat-samsung/dev_nand.c（平台设备）中的s3c_device_nand中的name字段保持一致，这样才能进行调用。否则可能会出现nand设备驱动不成功的现象。我的内核打印错误信息如下：[<c01469cc>] (strnlen+0x0/0x58) from [<c0148150>] (string+0x44/0xfc)[<c0148110>] (string+0x4/0xfc) from [<c0149270>] (vsnprintf+0x458/0xa28) r9:c033a5b0 r8:c7c27dd0 r7:c02efb56 r6:c02efb56 r5:c02efb57r4:00000000[<c0148e18>] (vsnprintf+0x0/0xa28) from [<c0149914>] (vscnprintf+0x14/0x20)[<c0149900>] (vscnprintf+0x0/0x20) from [<c003f6d4>] (vprintk+0x80/0x38c) r5:00000000 r4:c033a0f8[<c003f654>] (vprintk+0x0/0x38c) from [<c023cbf0>] (printk+0x28/0x30)[<c023cbc8>] (printk+0x0/0x30) from [<c017a1bc>] (add_mtd_partitions+0x2e0/0x7c0) r3:c031b578 r2:c031c1bc r1:70200000 r0:c02efb3c[<c0179edc>] (add_mtd_partitions+0x0/0x7c0) from [<c018487c>] (s3c24xx_nand_probe+0x4b4/0x774)[<c01843c8>] (s3c24xx_nand_probe+0x0/0x774) from [<c017167c>] (platform_drv_probe+0x20/0x24)[<c017165c>] (platform_drv_probe+0x0/0x24) from [<c01704b0>] (driver_probe_device+0x80/0x18c)[<c0170430>] (driver_probe_device+0x0/0x18c) from [<c0170650>] (__driver_attach+0x94/0x98)[<c01705bc>] (__driver_attach+0x0/0x98) from [<c016fcc8>] (bus_for_each_dev+0x68/0x94) r7:c01705bc r6:c0333834 r5:c7c27ee0 r4:00000000[<c016fc60>] (bus_for_each_dev+0x0/0x94) from [<c017033c>] (driver_attach+0x20/0x28) r7:c0333834 r6:c7c26000 r5:c0333834 r4:c02d872c[<c017031c>] (driver_attach+0x0/0x28) from [<c016f46c>] (bus_add_driver+0xa4/0x260)[<c016f3c8>] (bus_add_driver+0x0/0x260) from [<c0170914>] (driver_register+0x74/0x15c)[<c01708a0>] (driver_register+0x0/0x15c) from [<c0171968>] (platform_driver_register+0x4c/0x60) r7:c03393c0 r6:c7c26000 r5:c001db58 r4:c001dae0[<c017191c>] (platform_driver_register+0x0/0x60) from [<c0017638>] (s3c2410_nand_init+0x1c/0x28)[<c001761c>] (s3c2410_nand_init+0x0/0x28) from [<c0021368>] (do_one_initcall+0x38/0x1c4)[<c0021330>] (do_one_initcall+0x0/0x1c4) from [<c0008480>] (kernel_init+0xac/0x160)[<c00083d4>] (kernel_init+0x0/0x160) from [<c0041c44>] (do_exit+0x0/0x640) r7:00000000 r6:00000000 r5:00000000 r4:00000000Code: e24cb004 e3510000 e1a02000 0a00000d (e5d03000) ---[ end trace 48c84fc47f611133 ]---Kernel panic -

       2、解压Yaffs2并将其加入Linux内核（打补丁的方式）
       #cd yaffs2
       #./patch-ker.sh c /linux-2.6.34.2/
