我在打开supervivi烧写MINI2440内核,下载程序时都正常,但是下载文件系统映像却出现了“Could not found 'loadyaffs' command”
请问这是什么原因呢 ?

上面是在超级终端复制过来的
咨询了友善的技术支持客服,他远程协助,帮我再下载几遍,还是没解决问题。
然后他说”你用JLINK重新烧supervivi 就可以了”。
我便试一下用Jlink烧写。
按照Jlink手册,安装好Jlink
连接Jlink 和开发板
打开 开始->所有程序->SEGGER-> J-link ARM V4.08i->J-Flash Commader
如果连接好就会自动检测到芯片型号:
或者输入r命令也可以查看连接情况:
发现论坛不能发图片,唯有上传doc的附件还有Jlink配置文件的附件……[ 此帖被jiashu在2011-08-06 21:43重新编辑 ]
