开始以为是flash坏了,好害怕,后来才明白是JTAG接触不好.在烧写ppcboot时最好用tftp先下载,实在不行在用JTAG.
6.每次Mount上ramdisk.image后，不能umount？，主机上显示device is busy.
我的解决方法是打开 系统工具=>系统监视器,杀死最下面的fam进程就好了,我也不知道为什么,呵呵.
7.烧写ramdisk时发生这样的错误

经wpq和hn的指点知道是flash的第13个扇区坏了,可以跳过此坏扇区.flash是16M,共128个扇区,16M/128=128K,每个扇区是128k,换成16进制是20000,我的flash是0xc错了,故要跳过0xa和0xb两个扇区继续写,20000*2=40000,可以多跳几个扇区.写在11a0000中.
还有修改ppcboot重新编译,在\ppcboot-2\ppcboot-2.0.0-old\lib_arm下的armlinux.c的196行左右将0x140000改为1a0000,这里的40000和
140000都是逻辑地址,在flash中起始地址是1000000,故实际的地址分别为1040000和1140000,现在ramdisk改写在11a0000中了,呵呵.
好了,先写到这里了,希望对初学者有所帮助,小妹我还要继续下大家学习,在此对wpq和kangw表示最由衷的感谢.......~!~ |
