@whycan 测过了，是拉高的。高电平

shz18877605430

@whycan 这个蓝牙使能管脚会一直高吗？还是瞬间拉高然后回到低电平？

shz18877605430

@whycan 我测了的时候已经是拉低了（不上电默认和GND导通的），但是我还是把100k的电阻接上去做下拉了。还是出现这个问题。

F133跑bluez的时候，加载rtk_hciattach -n -s 115200 ttyS1 rtk_h5 &报错

运行了以下操作，rtl8723ds驱动已经运行，hci_uart.ko也运行了。

/etc/init.d/dbus start
echo 0 > /sys/class/rfkill/rfkill0/state
echo 1 > /sys/class/rfkill/rfkill0/state

加载rtk_hciattach -n -s 115200 ttyS1 rtk_h5 &的时候出现了协议不支持。但是内核已经开启了h5

各位大佬指教一下！！！

shz18877605430

8723ds的wlan0是能正常使用的，已经连接网络，能ping通。

大佬们，F133启动之后，/sys/class目录下找不到rfkill文件，配置已经开启，内核已经打开驱动，但是就是找不到rfkill目录。

T113跑bluez，bluetoothctl命令行操作的时候，手机能搜索到蓝牙，但是连接的时候一直连接不上，

大致流程如下操作：

/etc/init.d/dbus start
echo 0 > /sys/class/rfkill/rfkill0/state
echo 1 > /sys/class/rfkill/rfkill0/state
rtk_hciattach -n -s 115200 ttyS1 rtk_h5 & 	
hciconfig hci0 up
bluetoothd -C &
bluetoothctl
    ---->power on               //打开电源
    ---->discoverable on     //打开可发现
    ---->menu adv
         ---->name qq123      //设置蓝牙名字：qq123
         ---->back
    ---->advertise on           //广播

然后使用手机端的nrf connect助手搜索蓝牙，然后点击连接，但是连接不上，超时。

各位大佬，支支招！！！

@yunchawaishi 改一下dclk的屏幕，改到24Mhz，你现在肯定是48Mhz

shz18877605430

1、前序

前几天，买了个显示屏，5寸的RGB（800*480），遇到了个奇葩的问题，用了芒果的F133（MQ-R）板子，然后开启了lvgl的demo程序，发现屏幕整体图像很淡，有抖动波纹，有种撕裂的感觉，不信你看。可能不是很清晰，如下：

fe38c654-be68-4624-bcd3-4ca028bc165f-2D13F840CE14A7DBEBF4D6BB2B56EDC6.jpg

2、过程

当时出现了这个问题的时候，我首先看了设备树，发现设备树该改的都改了呀，也没看出啥毛病，然后一直在哪里乱调，群里问了大佬，得到了一点点的灵感，看来还是要上RGB显示屏的手册才行，如下图所示。

接着对着手册改，发现改了也没用，然后用了示波器测量dclk，发现时钟频率是48Mhz,哇，这么嗨高，手册显示最高也就27Mhz，以是我想了想，要不把频率降下来看看，然后打了两个补丁：

0001-disp-support-dynamic-adjust-tcon_div.patch：
    放置到 lichee/linux-5.4 目录中执行 
    git apply 0001-disp-support-dynamic-adjust-tcon_div.patch

0001-disp-support-dynamic-adjust-tcon_div-uboot.patch：
    放置到 lichee/brandy-2.0/u-boot-2018 目录中执行 
    git apply 0001-disp-support-dynamic-adjust-tcon_div-uboot.patch

补丁在这个全志服务平台上：https://open.allwinnertech.com/#/sdk/0?menuID=36

如图所示：

接着依旧于事无补，没用啊，算了，打了补丁就不管了，过了两天，带着板子到公司的示波器上测测波形，靠，还是48Mhz，无语，只能看看有没有同步吧，接着在uboot命令行下用了fdt print命令看了一下设备树的参数，发现和内核的设备树一样，这下扯淡了，证明改的设备树内啥问题啊，都更新进去了，于是我还是不死心，坚决拿uboot的设备树开刀，改成了和内核的参数一样，烧录进去，啪，示波器测量，24Mhz，成了。没了，请看下一集。

贴图贴图，收工。

贴个内核设备树（uboot也是一样的）上来给大家看看：

&lcd0 {
	lcd_used            = <1>;

	smart_color         = <90>;

	pinctrl-0 = <&rgb18_pins_a>;
	pinctrl-1 = <&rgb18_pins_b>;
};

// 记得改uboot的设备树，一定、一定、一定，重要的事情要说三遍！！！

shz18877605430

1、开了adb ,启动板子，然后使用命令：cat /sys/devices/platform/soc@3000000/soc@3000000:usbc0@0/usb_device
出现了截图中的第一个红框的现象。

2、重新给板子上电，在没有使用上面的命令，然后出现了截图中的第二个红框的现象。

各位大佬，求解！！！
