@forlinx 好家伙，真厉害

tivon

已解决
"/tina5.0-t113/openwrt/target/t113/t113-evb1_auto_nand/base-files/etc/inittab"中
修改如下

::sysinit:/etc/init.d/rcS S boot
::shutdown:/etc/init.d/rcS K shutdown
tts/0::askfirst:/bin/ash --login
ttyS0::askfirst:/bin/ash --login
tty1::askfirst:/bin/ash --login

@yuqingli t113从上电到，lvgl出界面，最快要几秒钟？

tivon

大家好，我发现T113的SDK中烧录到开发板中的rootfs比out目录中的少了很多文件，不知道是哪些配置文件在控制的？我该怎么把自己的文件也加进去？

手动改变引脚输出失败.jpg
echo PD22 1 > data
想改变PD22为高电平失败，function,dlevel,pull 都可以设置，就是data设置出错。

tivon

@tivon 3天了，晚上换个思路试试

@eestr 通信可以做成web的吗，有根USB线就和主机绑死了，做成web的还可以远程监控，与主机分开也可以做成摆件。

@z2500abc 看我以前的帖子

@lztmfx 谢谢，可能有用

@eddylin 电路上，clk串了个33欧电阻，其他都是直连，没有外部上拉电阻

修改内核设备树：

	spi0_pins_a: spi0@0 {
		pins = "PC2", "PC4", "PC5"; /*clk mosi miso hold wp*/
		function = "spi0";
		drive-strength = <10>;
	};

	spi0_pins_b: spi0@1 {
		pins = "PC3", "PC7", "PC6";
		function = "spi0";
		drive-strength = <10>;
		bias-pull-up;   /* only CS should be pulled up */
	};


	spi0_pins_c: spi0@2 {
		pins = "PC2", "PC3", "PC4", "PC5","PC6", "PC7";
		function = "gpio_in";
		drive-strength = <10>;
	};

修改uboot设备树：

&spi0_pins_a {
	allwinner,pins = "PC2", "PC4", "PC5";
	allwinner,pname = "spi0_sclk", "spi0_mosi","spi0_miso";
	allwinner,function = "spi0";
	allwinner,muxsel = <2>;
	allwinner,drive = <10>;
	allwinner,pull = <0>;

  allwinner,pname = "spi0_cs0", "spi0_hold", "spi0_wp";
  allwinner,function = "spi0";
  allwinner,muxsel = <2>;
  allwinner,drive = <10>;
  allwinner,pull = <1>; /* cs, hold, wp should be pulled up */

	allwinner,pull = <0>;
};

T113，tina5.0是这个位置
/openwrt/openwrt/package/base-files/files/etc/init.d
中建立脚本，名字随便取，值越大，越靠后
start()开机执行
stop()关机(poweroff)执行

#!/bin/sh /etc/rc.common

START=98
STOP=99
start() {
echo "rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr" > /dev/console
}
stop() {
echo "SSSSSSSSSSSSSSSTOPPPPPPPP" > /dev/console
}

经测试poweroff命令关机后
AVCC 有 1.8V
LDOA 有 1.8V
LDOB 有 1.5V
我想关机后，这些内部LDO也自动关闭，该怎么做？
