UBI只能挂载一次（AM3359)

Other Parts Discussed in Thread: AM3359, AM3517, AM3505

Hi，TI 专家

我们现在自己了块AM3359的板子，现在用的FLSAH 是K9F1G08U0C，我参照TI提供的文档通过tftp烧写内核和文件系统，ECC使用的是BCH8。烧写文件系统完后，系统只能正常启动一起，随后重新上电启动， ubi系统便不能正确加载。我发现K9F1G08是1bit的ECC，因此不能用BCH8，我有两个问题：

1、AM3359-EVM主要支持的Nandflash有哪些型号。

2、如果我要用K9F1G08,该如何烧写内核和ubi文件系统，是否需要修改驱动。

请专家指导下，很急。谢谢。

    您好，因为这个论坛是我们FAE在做支持，平时大家会在外面客户处做支持，很少在办公室，通常下午或晚上回来再回贴。我尽量给您问一下，尽快回复。谢谢理解！

    hi

    关于问题1：我们的AM335x芯片可以支持onfi和非onfi两种模式的nand，基本覆盖市面上大部分nand型号。你可以参考芯片spec（TRM）的Initialization那一章中的nand boot那一部分，有详细的说明。

    关于问题2：如果你的NAND只支持1bit ECC，那么你用u-boot烧写内核和文件系统的时候，就要选择1 bitECC 的烧写方式

    楼主问题解决了吗，我现在也遇到一样的问题，如果已经解决了那说下方法非常感谢

    你在UBIFS的时候用的mkfs.ubifs工具是多少版本的？mkfs.ubifs 1.5.0以下的好像不支持 -F 参数，做出来的ubi.img有问题，只能启动一次，启动后报ubi_io_read err ，ecc error之类的错，然后第二次ubifs损坏就无法启动了。

    如果是这样升级mtd-utils试试

    没有用到-F参数，我是用这个命令mkfs.ubifs -r rootfs  -m 2048  -e 129024  -c 812   -o ubifs.img生成镜像的，哥们你们怎么生成镜像的，移植是怎么操作的？谢谢

    am335x  要用-F 参数，

    另注意的是烧写长度要比image 长些，而且要按block对齐。

    按block对齐是什么意思

    http://processors.wiki.ti.com/index.php/UBIFS_Support#Creating_UBIFS_file_system

     

    Assuming

    1. NAND partition to be erased starts from "0x780000",
    2. NAND partition of size "0xF880000" and
    3. File system image size to be flashed is 0xFC0000 which is upward aligned to NAND block size
     
 u-boot# nand erase 0x780000 0xF880000
 u-boot# nand write 0x82000000 0x780000 0xFC0000

    我用的是AM3517，内核是2.6.37，我用uboot烧写文件系统，烧写好后启动没有问题，但是之后的启动就都不行了，不过重新烧写文件系统又可以了，但只能成功一次，也就是每次启动都要重新烧写文件系统才行。
    boot烧写UBI操作命令如下：
    一：mtdpart default
    二：nand erase root
    三：ubi part root
    四： ubi create rootfs-nand
    五：fatload usb 0:1 0x82000000 ubifs.img 0x2293800
    六：ubi write 0x82000000 rootfs-nand 0x2293800 帮我看看那里有问题

    0x2293800  是按nand flash 对齐的吗？

    改成0x2300000 再试下

    0x2293800是文件的大小，我把它改为0xf880000 结果还是一样，郁闷了 搞了很久了

    第一次启动之后是不是有报错？第二次不能启动死在哪里？可以贴这两次启动log看看。

    第一次启动没有报错，

    第二次就不能正常启动了

    Hi

    使用TI官网prebuilt 的相应ubi.img 试试。

    UBI error: ubi_io_read: error -74 (ECC error) while reading 64 bytes from PEB 2:0, read 64 bytes。

    还是像你的ubi.img做的有问题，我用的是AM3359，当制作的ubi.img 有问题，报的错与你相同

    这是我的 sudo mkfs.ubifs -r ./ubi_rootfs/ -F -m 2048 -e 126976 -c 1580 -o ubifs.img ; sudo ubinize -o ubi.img -m 2048 -p 128KiB -s 512 -O 2048 ubinize.cfg 和官网文档说明是一样的。

    我是用这个命令生成镜像的 mkfs.ubifs -r target/ -F -m 2048 -e 129024 -c 1580 -o ubifs.img

    二：nand erase root
    三：ubi part root

    四： ubi create rootfs-nand
    五：fatload usb 0:1 0x82000000 ubifs.img 0x2293800
    六：ubi write 0x82000000 rootfs-nand 0x2293800
    然后重启

    uboot中configs里面的am3517_evm.h文件修改添加如下内容：
    #define CONFIG_SYS_MALLOC_LEN             (CONFIG_ENV_SIZE+  1024*1024)
    #define CONFIG_MTD_DEVICE          1
    #define CONFIG_MTD_PARTITIONS        1

                                       "5m(kernel)," \
                                       "-(root)"
    已经搞了很久了 郁闷了，哥们帮帮忙

    Hi：

    五：fatload usb 0:1 0x82000000 ubifs.img 0x2293800 你烧写的是 ubifs.img？

    http://processors.wiki.ti.com/index.php/UBIFS_Support上说先使用mkfs.ubifs生成ubifs.img，

    The output of the above command, ubifs.img is fed into the 'ubinize' program to wrap it into a UBI image.

      The images produced by mkfs.ubifs must be further fed to the ubinize tool to create a UBI image which must be put to the raw flash to be used a UBI partition. 
    再用ubinize创建ubi.img,
    The output of the above command, 'ubi.img' is the required image.

    我现在用ubinize -o ubi.img   -m 2048   -p 128KiB   -s 512   ubinize.cfg
    

    在uboot下操作如下：
    

    fatload usb 0:1 0x82000000 ubi.img 0x1fe0000
    nand erase 0x780000 0xf880000
    

    nand write 0x82000000 0x780000 0x1fe0000
    

    但还是不行，你在uboot下是怎么操作的

    Hi:
    

    我uboot 做法如下
    

    fatload mmc 0 0x81000000 ubi.img
     nandecc hw 2
     nand erase 0x00780000 0x07460000
     nand write.i 0x81000000 0x00780000 0x07460000
    

    如果可以的话，你可以先做nand scrub.chip 再重新烧写uboot kernel ubi

    把ubi.img放在文件系统的根目录，先从sd卡启动ubi，然后用ubiformat /dev/mtd7 -f /ubi.img这个命令烧写ubi到nand flash，第二次启动也正常起来了

    他不是从sd卡启动ubi
    

    是把ubi的img放在sd卡中，然后从sd启动，把ubi的img烧写到nand中
