这俩天遇到了一个很奇怪的问题
通过SD卡启动
在uboot下，将nand flash 擦除掉之后，执行saveenv，重启，再通过SD卡启动
就会打印出ECC: uncorrectable 错误
目前定位到是elm模块，ECC error-location process failed，就是说elm模块错误定位失败，导致打印出这个错误
但为什么elm 错误定位失败，还没找到原因
TI的专家们，有没有什么建议啊？卡在这里好几天了
你好！能否详细提供如下信息？
使用SDK的版本？
使用u-boot烧写什么image?烧写命令如何？
使用的版本是ti-sdk-am335x-evm-06.00.00.00
还未烧写uboot 到nand中，从sd卡启动，启动信息如下：
U-Boot SPL 2013.01.01 (Sep 03 2014 - 17:10:10)OMAP SD/MMC: 0reading u-boot.imgreading u-boot.imgU-Boot 2013.01.01 (Sep 03 2014 - 17:10:10)I2C: readyDRAM: 512 MiBWARNING: Caches not enabledNAND: NAND device: Manufacturer ID: 0x2c, Chip ID: 0xda (Micron NAND 256MiB 3,3V 8-bit)256 MiBMMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1*** Warning - bad CRC, using default environmentNet: <ethaddr> not set.

saveenv之后，再从sd卡启动

报ecc的错误
没看到U-boot下的烧写命令啊，这个NAND的型号和EVM板上是一样的么？
