Linux 烧写
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,
第二:第一步完成之后,在nor下面启动,选择1,烧写uboot,文件还是uboot
第三:在nand模式下启动,进入烧写模式,
选择2,烧写eboot,
选择3,烧写zImage,
选择b,烧写logo,
最后选择6,烧写文件系统,就是那个root_qt的文件,
烧写完后,选择8可以进入linux系统,
按照以上步骤进行的,最后按8,终端显示如下:

怎么解决呢?
还有eboot不是烧写wince系统才用吗?这里烧写有什么用?
我选了EBOOT_Q35_20100120.nb0烧写进去了。 |
