am335x串口死掉

另外我是使用的sd启动，文件系统也在sd卡上。

刚才移植一个3.12的内核， 也没有这个问题。

还到4.1的内核上面就有问题。

是不是内核少选了什么配置

看你上面给的log，rtc哪块挂了。在你移植的这个有问题版本的内核中，RTC的相关配置是不是没有被去掉？你把在am33xx.dtsi中关于RTC的部分注释掉，然后查一下在你自己使用的dts文件中有没有，有的话也干掉。然后启动试试。

还是不行， 都可以看到登录了。然后串口就没法输入了。在这之前是可以敲回车的， 能看到敲了回车调试串口有空行。

现在到最后一步登录的时候， 调试串口无法操作。

最后这条/etc/rc5.d/S98thermal-zone-init: line 7: /sys/class/thermal/thermal_zone*/mode: No such file or directory 是不影响启动的。

在linux3.14上面也有这个部分报错都是可以进入命令行的。

解决了rtc问题， 还是不行。

我写了一个简单的驱动，定时器每隔一秒打印一条信息。

但是在调试串口假死之后， 这个驱动就再也没打印信息了。

尝试使用8250 -omap的串口驱动， 然后传串口参数console=ttyS0,115200n8, 修改/etc/inittab,

S:2345:respawn:/sbin/getty 115200 ttyS0

或者传参数 console=ttyO0,115200n8 /etc/inittab

S:2345:respawn:/sbin/getty 115200 ttyO0

使用omap-serial驱动，

同样会出现该问题。

文件系统是我从官方sdk里面取的， 换成其他内核可以使用， 不会有这个问题。

内核配置文件我使用的是

arch/arm/configs/tisdk_am335x-evm_defconfig 使用sd卡启动。

你看你的log这里：

[    0.515849] console [ttyS0] disabled
[    0.516021] 44e09000.serial: ttyS0 at MMIO 0x44e09000 (irq = 158, base_baud = 3000000) is a 8250
[    1.174807] console [ttyS0] enabled

你是改了驱动哪里了吗？你在移植的时候，其实只要动dts文件的配置就好了，driver部分的话没什么要动的。能否简要描述一下你移植都改了哪些文件。

现在内核里面有两个omap串口驱动，  一个是基于8250的

另一个是omap-serial.c

我参考的http://processors.wiki.ti.com/index.php/Sitara_Linux_UART_-_Switching_to_8250_Driver

两个驱动我都试过，都不行。

驱动我没有改过。

目前只是修改了lcd， 以及pmic 因为这个和sd卡有关， 然后移植了uart0， 1， 2， 3， 4，

其余的没动过。
