WhyCan Forum(哇酷开发者社区)

根据网上的修改方法，将调试串口从Uart0修改成Uart1，修改的文件有如下：
1)    sys_config.fex文件中Debug Port部分：
uart_debug_port = 1
uart_debug_tx   = port:PG06<2><1><default><default>
uart_debug_rx   = port:PG07<2><1><default><default>
2)    Uboot配置文件sun8iw20p_defconfig增加uart1配置
# Serial Drivers
CONFIG_BAUDRATE=115200
CONFIG_SPECIFY_CONSOLE_INDEX=y
CONFIG_CONS_INDEX=2
3)    env.cfg里
earlyprintk=sunxi-uart,0x02500400
console=ttyS1,115200
4)    board.dts增加uart1设备引脚描述：
    uart1_pins_a: uart1_pins@0 {  /* For EVB1 board */
        pins = "PG6", "PG7";
        function = "uart1";
        drive-strength = <10>;
        bias-pull-up;
    };

    uart1_pins_b: uart1_pins {  /* For EVB1 board */
        pins = "PG6", "PG7";
        function = "gpio_in";
    };

&uart1 {
    pinctrl-names = "default", "sleep";
    pinctrl-0 = <&uart1_pins_a>;
    pinctrl-1 = <&uart1_pins_b>;
    status = "okay";
};
5)    修改kernel_menuconfig中linux的Debug输出映射

经过如下修改后，T113运行后Uboot和前半段Linux都能够正常打印，但是一会就无法输出了，请教有修改成功的大神帮忙看看问题，谢谢！
ps：打印输入如下：
