EA6500 V1更换nand flash后不能刷机，求高手指点
EA6500V1原来的三星nand flash有好多坏块，不能刷dd固件，只能原厂，后来换了个新的闪存，上去，可以识别，但是固件刷不进去，求cfe下格式化或者清空nand flash的命令、、、、

备注下：tftp和ttl命令强刷都不行，都是提示校验错误。。。。 原厂固件比dd好用多了 tt的固件目前支持不好 建议用原厂 :lol已经搞定了，dd功能多呗，原厂固件要来没啥用。。。。 支持一下 zhujunsq 发表于 2015-4-25 21:45

请问楼主如何搞好的？我的也需要清掉nand数据，可否告知我具体操作步骤 难道是用编程器写上的？
