标题: 进军ARM9,下午成功的烧写了Boot,哈哈。就像是PC的BIOS

即使一小步也有新高度!




     就像当年学单片机一样,怀着无比崇拜和好奇的心情搞ARM9,大体看了下ARM9的架构,和ARM7基本是一样的,唯一不同的是他的boot是要单独烧写的,就是PC机的bios一样,忙碌了一下午,听着歌,研究怎么烧写,主要是刚开始路子没选对,走了弯路,其实直接用jtag就行,直接烧写,很简单的,我烧的步骤如下:
第一歩: 加载预先编译的启动文件,
第二部选择FLASH:norflash,或者NAND flash,
第三部:烧写
烧写完毕之后,提示你成功,然后你重新上电,串口就打印如下:成功了!
