IMX6串口0造成崩溃的问题

Question asked by Yi Liu on Jan 25, 2016

我们有客户项目在使用串口时遇到死机问题,具体情况描述如下 :

客户使用串口ttymxc0是正常的,但考虑到有些客户需要用到串口,需保留这个作为调试用,所以在开机时候在设置环境变量串口做了更改。这样配置后造成系统崩溃,先前客户在IMX53也这样用过但是正常的,想请教下是什么原因?谢谢!

 

 

(已让工程师用官网镜像实验,同样会有这个问题)下面是客户邮件内容:

          您们好!

关于/dev/ttymxc0 出现死机的问题。我用了官方的包也是一样会死。

    我们用的版本及其硬件信息如下:android4.3

一、设置 console=ttymxc0  (这样是正常的)

root@sabresd_6dq:/ #

root@sabresd_6dq:/ # cat /proc/cmdline

no_console_suspend console=ttymxc0,115200 root=/dev/mmcblk0p1 init=/init video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666,bpp=32 ldb=sin0 video=mxcfb1:off video=mxcfb2:off fbmem=10M fb0base=0x17b00000 vmalloc=400M androidboot.console=ttymxc0 androidboot.hardware=freescale

root@sabresd_6dq:/ #

root@sabresd_6dq:/ #

 

130|root@sabresd_6dq:/ # echo 0123 > /dev/ttymxc0                             

 

0123

root@sabresd_6dq:/ #

二、设置 console=ttymxc1 (我们是要设置为console=null,这样可以理由ttymxc0这个串口

 

root@sabresd_6dq:/ #

root@sabresd_6dq:/ #

 

root@sabresd_6dq:/ # cat /proc/cmdline

 

no_console_suspend console=ttymxc1,115200 root=/dev/mmcblk0p1 init=/init video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666,bpp=32 ldb=sin0 video=mxcfb1:off video=mxcfb2:off fbmem=10M fb0base=0x17b00000 vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale
