烧写内核和文件系统后系统无法启动呀！！

刚买啦TQ2440开发板（东华3.5英寸屏）试着把出厂烧录镜像合集里的zImage_2.6.25.8_W35_64MB.bin，和root_qtopia_2.2.0_2.6.30.4_64MB.bin 烧写到开发板，发现系统不能启动了，超级终端里显示：

是不是NAND flash坏了。

你下错了 应该是后缀256MB

问题解决烧错镜像了
:D

NAND flash 坏块还是很多呀

4# mkmkbird
什么意思？

制造工艺还是不成熟呀

zImage_2.6.25.8_W35_64MB.bin和zImage_2.6.25.8_W35_256MB.bin有什么区别呢？
只是Nand容量的区别？为什么对启动会造成影响呢？
难道需要不同的驱动？
如果是Linux上，同样的镜像覆盖到80G，还是160G硬盘是不需要使用不同镜像的啊?

mkmkbird 发表于 2009-10-7 19:42

是否有程序可以统计坏块数目的？

没见过,呵呵！网上找找吧

在我们移植手册里面讲了两个镜像不同之处的，在Nand Flash移植章节。
如果出现很多坏块，最大的可能性是uboot或Linux系统导致的人为坏块，伪坏块。
在uboot下面使用：9-》1-》y-》回车即可格式化Nand Flash，然后马上重新烧写各个镜像即可。
