WIFI 驱动参考 https://linux-sunxi.org/Wifi
RTL8189FTV
Driver has its own repository:git clone https://github.com/jwrdegoede/rtl8189ES_linux.git
cd rtl8189ES_linux.git
git checkout -B rtl8189fs origin/rtl8189fs
make -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnu- KSRC=../linux复制到 lichee/linux-5.4/drivers/net/wireless/ 目录。
我编译之后，插入驱动，没有报错。也没有wlan0出来，是不是dts没有改导致，dts需要修改什么
持续填坑中：
如果需要自己编译驱动，或是应用，可以参考这个命令：
make -j4 ARCH=riscv CROSS_COMPILE=/home/soso/D1/out/d1-mangopi_mq_rgb800x480_gt9xx/staging_dir/toolchain/bin/riscv64-unknown-linux-gnu- KSRC=/home/soso/D1/out/d1-mangopi_mq_rgb800x480_gt9xx/compile_dir/target/linux-d1-mangopi_mq_rgb800x480_gt9xx/linux-5.4.61/
以上命令是d1s，编译wifi驱动。可以看到tina的交叉编译器，内核目录存放规律~~
@yuzukitsuru 在 芒果派 MQ Pro，MQ 的板级配置文件 中说：
下载：
同时有D1-H与D1s的配置文件。
直接复制进 tina-d1-h 就可以了
实时更新仓库（上面那个tar不想打包了，之后更新丢github上）
这个配置文件，针对 的是这个sdk？覆盖这个sdk的文件即可是吧~~

烧写篇
1.下载驱动 全志USB烧录驱动20201229
2.下载烧写工具AllwinnertechPhoeniSuitRelease20201225.zip 以及最新镜像（https://www.aw-ol.com/downloads?cat=5）
3.软件打开后。提示设备连接，点击全盘刷新。设备会断开。然后正常烧录。（以上是官方原文说法~~）
4.碰到点击立即烧写后，设备usb断开，但是没有其他反应。此时可以按住uboout键，然后按重启键，或是uboot启动的时候按住2.
调整了极性后。能出图。现在开始进入触摸的坑：
目前启动后，i2c报错。dts按照荔枝派86盒子的配置配置触摸

目前调整了时序，能正常显示，但是有明显的波纹。屏厂家建议是修改clk极性。但是在dts里面还没找到配置。非sync_polarity以及clk_phase.这clk极性是指哪个配置？
二、填坑之spi
1.背景
受限于开发板引出io不是很理想，暂时先用麻雀d1s试了一把spi，并能正常显示图片。目前使用spi1进行驱动。如果是spi0，直接按照帖子中的参考帖子配置即可。具体调试过程：https://bbs.aw-ol.com/topic/1657/麻雀-d1s-spi-tft-开坑/24?_=1657154236388
2.解决方法：
不要在意这些细节。哈哈a.dts
spi1_pins_a: spi1@0 {
pins = "PD11", "PD12"; /* clk, mosi */
function = "spi1";
drive-strength = <10>;
};
spi1_pins_b: spi1@1 {
pins = "PD10" ;
function = "spi1";
drive-strength = <10>;
bias-pull-up; /* cs */
};
&spi1 {
clock-frequency = <100000000>;
pinctrl-0 = <&spi1_pins_a &spi1_pins_b>;
pinctrl-names = "default";/*原贴少了这个配置*/
status = "okay";
st7789v@0 {
status = "okay";
compatible = "sitronix,st7789v";
reg = <0>;
spi-max-frequency = <32000000>;
rotate = <90>;
rgb;
fps = <30>;
buswidth = <8>;
reset = <&pio PD 13 GPIO_ACTIVE_LOW>;
dc = <&pio PD 14 GPIO_ACTIVE_LOW>;
led = <&pio PD 15 GPIO_ACTIVE_HIGH>;
debug = <1>;
};
};
另外需要按照帖子中大神的回复，修改spi1的地址大小。如果图片显示异常，或是显示不全，请修改便宜。240*280，y偏移20，x不用便宜即可。至于这个值怎么查出来，卖个关子~~
3.留坑
目前能正常显示图片，但是播放视频直接退出。可能需要设置缩放。这个后续验证后再续楼。
4.最后，有图有真像
前期工作：
1.使用荔枝派d1的驱动，包含dts以及驱动，仅改linux部分，uboot部分没有修改；
2.关闭uboot的lcd驱动
3.目前已经能显示，但是显示的图像变成“双屏”。spi的初始化已经在树莓派上验证过。能正常显示。应该是全志平台哪里配置不对。
目前尝试：
a.关闭uboot的lcd驱动，修改uboot的lcd的配置,将分辨率调成一致，问题依旧
b.目前这个方屏跟荔枝派不是一个型号。但是都是7701s。480*480.
以下是lcd的dts

lcd_used = <1>;
lcd_driver_name = "st7701s_rgb";

@whycan tplayerdemo 播放一个mp4视频，用d1s。有时候播放要卡很久才音视频同步，然后基本上播放10分钟左右就卡住了。这个 现象正常不。感觉是内存不够，还没细看。你们之前测试效果如何~~
@jr_online 我用到的是方屏，也是和你一样，lvgl花屏，然后其他显示显示的是变成上下分屏，内容一致，要修改哪里？uboot的分辨率没同步设置？我这边是关了uboot的lcd驱动的
@whycan 之后在烧好tina镜像的卡上新建一个ext4分区，这一步怎么操作~~ 有没有已经搞好的rootfs，直接抄作业。哈哈
@soso90 在 麻雀 d1s spi tft 开坑 中说：
@yteraa
tf卡启动，没有修改到tf卡相关。只是添加了spi和改了你说的寄存器范围。刚才spi的dts错误的话，还能识别到。看日志好像现在是识别不到tf卡。
初步判断，有可能是io口引用冲突导致。这边有个疑问，d1s少了部分io。那么io计算方法是否还是和d1一致，也是按照每个pin有多少个做偏移，还是按照固定的io数去计算
@yteraa tf卡启动，没有修改到tf卡相关。只是添加了spi和改了你说的寄存器范围。刚才spi的dts错误的话，还能识别到。看日志好像现在是识别不到tf卡。
@yteraa 现在能识别，也正常挂载7789，就是系统根目录挂不了。真是奇怪~~没有改其他地方，就加了一个pin-name加了default这个，之前dts少了这个，才报申请io失败
修改了报错。现在能挂载上驱动。不过启动后，居然挂载不了根目录

@yteraa fbtft没有输出，spi这边还是报那个申请失败：sunxi_spi_probe()2476 - [spi1] Req mem region failed。这个spi失败的话，后面应该也不会去挂载fbtft吧
@yteraa 按照你说的，改了spi的范围，重新make和pack，还是报这个错误。是哪里还要配置？谢谢哈~ 看来这个东西，应该玩的人也少

0.保姆贴：https://blog.csdn.net/weixin_43094346/article/details/125327521
【保姆级教程】全志V853开发板硬件指南
1.即将使用的硬件：
a.摄像头。做简单识别，根据人脸识别不同人，显示不同表情或是动作
b.串口，调试用
c.wifi模块，联网用。这年头，没网络你别跟我说其他~~
d.声卡，麦克风，主要完成录音，语音识别以及播放音频。
e.pwm控制舵机，期望值是驱动机械，暂定是微型坦克
f.spi tft，可以显示摄像头以及做一些表情
按照保姆级教程， 结合上述硬件需求
a. 先上电，看串口输出情况，以及登录到系统看看，接线如下，波特率115200
b.通过adb连接，下载adb https://www.aw-ol.com/downloads?cat=5
可以打开各种软件管家，就能安装驱动，驱动识别成功后，即可。如果不烧系统，用adb，控制，和上传足矣~~
c.联网
root@TinaLinux:/# wifi -o sta
root@TinaLinux:/# wifi -c awol 12345678
然后就可以ifconfig看到wlan0上有ip，可以愉快ping www.baidu.com
惊奇发现有iperf，后面打流看看
python居然没有带，蛋蛋的忧伤，看来编译sdk是跑不掉。。。
d.其他 lv_examples 没找到。。。有可能出厂固件可能不是最新，看来烧固件是接下来要搞的~~~
问题：仅仅从固件层面，简单测试发现问题，需要进一步核实以及查找原因。 摄像头图像颜色偏浅 ，默认固件没有lvgl例子，无法控制lcd，从event0没有获取到触摸数据，测试df_andi报错，报错如下：

手上有个st7789的屏，开坑，驱动这个屏，目前spi0引出到spi flash，空间比较小。不好飞线。考虑使用gpio模拟或是spi1.有使用经验的朋友可以交流一下
@whycan 看d1s好像只有18个io接666,888的话，PD口好像不够吧。可以怎么连接~
