EA6500  V1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、、、、 Broadcom CFE version 1.0.37 for BCM947XX (32bit,SP,LE) Build Date: Wed Jun 13 14:12:48 CST 2012 (lzh@team2compiler2) Copyright (C) 2000-2008 Broadcom Corporation.

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

已经搞定了，dd功能多呗，原厂固件要来没啥用。。。。

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？
