CB运行android系统,在开机与关机时,均会在串口输出一串信息.
如关机时输出
[ 396.810000] SysRq : Emergency Remount R/O
[ 396.880000] EXT4-fs (nandd): re-mounted. Opts: (null)
[ 398.330000] EXT4-fs (nande): re-mounted. Opts: (null)
[ 398.400000] EXT4-fs (nandh): re-mounted. Opts: (null)
[ 398.470000] Emergency Remount complete
[ 399.230000] [sw-ohci2]: shutdown start
[ 399.290000] [sw-ohci2]: close clock
[ 399.330000] [sw-ohci2]: shutdown end
[ 399.380000] [sw-ehci2]: shutdown start
[ 399.420000] [sw-ehci2]: Set USB Power OFF
[ 399.470000] [sw-ehci2]: close clock
[ 399.530000] [sw-ehci2]: shutdown end
[ 399.570000] [sw-ohci1]: shutdown start
[ 399.620000] [sw-ohci1]: close clock
[ 399.660000] [sw-ohci1]: shutdown end
[ 399.710000] [sw-ehci1]: shutdown start
[ 399.750000] [sw-ehci1]: Set USB Power OFF
[ 399.800000] [sw-ehci1]: close clock
[ 399.840000] [sw-ehci1]: shutdown end
[ 399.890000] [NAND]shutdown
[ 399.930000] nand try to shutdown 0 time
[ 401.500000] Nand flash shutdown ok!
[ 401.560000] Power down.
[ 401.590000] [axp] send power-off command!
其次,在与PC进行串口通信时,如果PC发送一串数据到CB,CB接收到再回传给PC,在回传的数据中,也会插入
/dev/ttyS0[3]: not found
事实上,CB使用的串口就是ttyS0,通过ttyS0能发送与接收数据,但是就会莫名接收到额外的外部数据.
遇到这样的情况,该如何处理?
