am3354 android4.2 uEnv.txt 文档



我是按照 Developer Guide  对 SD 卡进行分区,.txt 文档如下,

File: uEnv.txt
bootargs=console=ttyO0,115200n8 androidboot.console=ttyO0 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait init=/init ip=off
bootcmd=mmc rescan ; fatload mmc 0 81000000 uImage ; bootm 81000000
uenvcmd=boot
 
但是 启动到kernel 的时候 
 Kernel command line 是这样的  [    0.000000] Kernel command line: console=ttyO0,115200n8 root=/dev/mmcblk0p2 ro rootfstype=ext3 rootwait ip=none 
请问是什么原因导致的??该如何修改?谢谢,
另外还有个问题 我的板子启动后一直打印
 root@android:/ # [   28.379282] init: untracked pid 325 exited
 [   28.556780] init: untracked pid 329 exited 
[   34.454188] init: untracked pid 332 exited [   34.515079] init: untracked pid 334 exited
 [   44.428124] init: untracked pid 338 exited [   49.125667] init: untracked pid 344 exited
 [   50.079104] init: untracked pid 348 exited    请问是没有屏幕的问题吗?如果不是该怎么解决?? 谢谢
