关于AM335x Nand 启动UBI出错的问题

根据错误提示，好像是和nand ecc校验有关

根据提示做了验证，u-boot中都是采用nandecc hw bch8校验了，同时查了在am335x-bone.dts文件中的参数信息也是bch8

am335x-bone.dts

另外如果将am335x-bone.dts中的nand ecc 改成none 

nand-bus-width = <8>;

gpmc,device-nand = "true";

则超级终端的输出有所变化：

该从哪几个方面去修改nand ecc呢，话说linux 3.12中升级成ARM_Device_Tree后还不大理解

建议你照如下这个文档做一遍ubifs:http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/59921.aspx

最好不使用SDK里面自带的.ubi文件

感谢 Jian Zhou，按照提供的说明重新做了ubi文件，发现问题是在u-boot的启动参数设置，虽然还不知道为什么，但是

将bootargs中的ubi.mtd=NAND.rootfs 直接改成mtd partition id了：ubi.mtd=9，UBI文件系统顺利加载起来了

你好，我就是按着这个这篇文档做的，到最后依然没有能加载ubifs。

简单描述一下我的情况：我们的板子是参考BBB做的，但没有eeprom，板子没有eMMC，而是用的nand flash，除此之外和BBB没多大区别了，现在用的这款主芯片是AM3352。在uboot中改了iic读取eeprom部分，改成BBB的信息，让内核以为是BBB，然后启动。用的SDK包是SDK6.0，内核是3.2，uboot是2013.01.01版本。目前做的SD卡启动，完全没有问题，uboot、kernel和文件系统都没有问题，能启动正常。

遇到了两个问题：1. SD卡启动uboot后，把MLO, u-boot.img, uImage, ubi,img烧写到板子的nand里，然后上电后，串口打印一直是CCC，并没有从nand启动，板子的SYSBOOT[4:0]=10011b,按说启动顺序是NAND-NANDI2C-MMC-UART，应该从nand启动的，但是没有。

2.从SD卡启动uboot后，烧写上面那些文件后，拔掉SD卡，输入boot命令，会从nand读取内核，并启动，但是到了要打开ubi0:rootfs的时候出错了，详细的启动打印信息在下面：

请各位前辈和TI的工程师，帮忙分析一下问题可能出在哪里，试了很多方法都不行，这里先谢谢各位大牛了。
