*** Warning - bad CRC or NAND, using default environment

不知道是什么原因，烧写不上Linux系统，亚瑟王帮帮忙啊

烧写了几次，一直都是这样，是不是还有什么原因？

你烧写的文件系统名称是什么？

只烧了个uboot到板子上，一直重启，使用手册上说：（使用旧版本的 uboot 烧写新版本的 Linux 镜像会导致开发板一直重启，因为 uboot启动时读取 zImage 镜像的位置不对导致数据错误引起重启的。），可我还只烧了个uboot啊？？？应该怎么修改uboot啊？怎么解决？？？

进入uboot下载模式，使用命令1更新uboot镜像即可。

烧写了uboot之后还要重新下载吗？

建议重新下载内核、文件系统，开机logo

我也遇到这种情况 但一直没发解决

恢复出厂设置：


Linux 烧写,以下以东华3.5寸屏配256MB NAND FLASH为例：
第一：首先烧写nor:什么都没有的开发板，需要在nor flash 烧写uboot文件，用h-jtag或者j-link，具体方法请参考手册第四章，一般来说我们的板子都已经烧好了的，如果没有被擦除，可以跳过此步。
第二：第一步完成之后，在nor下面启动，选择1，烧写TQ2440_CD\出厂烧录镜像合集\东华3.5寸屏的镜像\U-boot\u-boot_W35.bin
第三：在nand模式下启动，开机按空格进入烧写模式，然后选择3，烧写TQ2440_CD\出厂烧录镜像合集\东华3.5寸屏的镜像\Linux-2.6.30.4\zImage_2.6.30.4_W35_256MB.bin，选择b，烧写TQ2440_CD\出厂烧录镜像合集\东华3.5寸屏的镜像\Logo\logo_320_240.bin，最后选择6，烧写文件系统TQ2440_CD\出厂烧录镜像合集\Linux文件系统镜像\root_qtopia_2.2.0_2.6.30.4_256MB.bin.
提示：如果NOR已经有UBOOT了，就可跳过第一步,另外第三步中我们也可以不换启动模式，直接在NOR下进行 （ 选择3，烧写zImage，选择b，烧写logo，最后选择6，烧写文件系统.）也是一样的！还有一点就是第一次烧写系统之后要进行触摸屏的校正，连续点击十字架中心五次即可！

晕这个只烧写UBOOT的原因啊，nor flash烧写UBOOT之后，从nor flash 启动的话不会出现这样的问题，烧写到nand flash一定要按空格在能进入UBOOT菜单，然后可以按照菜单用USB烧写，或者是用UBOOT的命令进行tftp烧写，具体烧写方法光盘里有视频教程，不多说了，要注意的一点是如果内核和文件系统不匹配的话也会出现类似的错误，按找说明来。

4楼和8楼只烧写了uboot，没有烧写Linux内核和文件系统，uboot启动时找不到正确的数据，肯定就报错了。
