这里直接连接了电源，设备树中还要加sunxi,uart-485oe-gpios这个属性吗，还是说这种情况有其他写法

@awwwwa 好的谢谢

@awwwwa 了解了, 非常感谢

测试使用串口 ttyS1 正常，关闭 CONFIG_SERIAL_8250

@ethan_00 可以通过U盘来写入设备树dtb overlays覆盖原屏参

Makefile:68: *** missing separator. Stop.

这个错误通常表示在 Makefile 的第 68 行或附近存在语法错误。Makefile 中使用的规则必须遵循严格的缩进规范，通常是使用 Tab 键进行缩进，而不是空格。

请检查 Makefile 第 68 行附近的代码，确保每个规则的命令部分都以 Tab 键开头，并且规则名称和命令之间使用冒号（:）分隔。此外，还需要确认 Makefile 的每一行都是使用相同的缩进方式，要么都是 Tab，要么都是空格，不要混用。

默认HDMI不开，需要命令开启

cd /sys/kernel/debug/dispdbg echo disp0 > name; echo switch1 > command; echo 4 10 0 0 0x4 0x101 0 0 0 8 > param; echo 1 > start;

RI-2020.5-linux 编译器需要向购买开发板的商家/代理提交申请，需要提供自己的HIFI5 DSP Xtensa Xplorer的证明

@zifeiyu 那为什么pack打包到固件的有，刷进去就没了，是不是刷写到emmc但是TF卡启动了？

请贴出LOG，截图

@lyg116 已更换镜像解决结贴

您看下配置文件，基本上使用默认的配置。有没可能内核固件版本不对，您这边能用vlc出图像吗？

@yuri123088 加我qq: 535888978 我发开发环境运行脚本给你，这个问题应该可以解决。

搞明白了，这两句配置搞得问题：
CONFIG_BCMDHD_FW_PATH="/etc/firmware/fw_bcmdhd.bin"
CONFIG_BCMDHD_NVRAM_PATH="/etc/firmware/nvram.txt" \

@whycanservice 感谢！

@misay 您好，请问这个具体要怎么解决呀，我用yolov5-7.0的模型会有这个问题，6.0没有，但是需要用到7.0的语义分割模型。想请教下如何解决，谢谢大佬

@daming123 在 全志T113 接LVDS 屏幕 中说：

用了MQ-r的板子，接上LVDS屏幕
把LCD的引脚引出来，淘宝买了一个40Pin排线，把2.54mm针的距离引出来
557dce4b-cc1d-4993-9716-76aa2010f34c-image.png
然后查看原理图，查看board.dts，查看引脚，接上
由于LVDS屏幕需要一个正负电压，查看规格书，
922be46d-5aab-4c6a-9060-48d2497ee786-image.png
VGH 18V，VGL -10V，手头没有，于是淘宝找了一个LVDS电压转接板，把负电压，正电压，升压得到合适的电压，下面是升级板
a846596c-fc20-40dd-9c82-7c10ee399a53-image.png
接上屏幕，另外一边接转接板。修改dts文件如下
&lcd0 {
lcd_used = <1>;

lcd_driver_name = "default_lcd";
lcd_if = <3>;

lcd_x = <1024>;
lcd_y = <600>;
lcd_width = <150>;
lcd_height = <94>;
lcd_dclk_freq = <51>;

lcd_pwm_used = <0>;

lcd_hbp = <80>;
lcd_ht = <1344>;
lcd_hspw = <20>;
lcd_vbp = <10>;
lcd_vt = <635>;
lcd_vspw = <10>;

lcd_lvds_if = <0>;
lcd_lvds_colordepth = <1>;
lcd_lvds_mode = <1>;

lcd_frm = <1>;
lcd_hv_clk_phase = <0>;
lcd_hv_sync_polarity= <0>;
lcd_gamma_en = <0>;
lcd_bright_curve_en = <0>;
lcd_cmap_en = <0>;

pinctrl-0 = <&lvds0_pins_a>;
pinctrl-1 = <&lvds0_pins_b>;
};
最后上电，成功点亮
e1f09b5a-84cc-4c7a-b4b4-f75da446cefd-image.png
完成，走了很多弯路，因为对LVDS不了解，淘宝买东西耽搁几天时间。大家可以对照着来，如果用到LVDS的话。

亲，有 LVDS 适配步骤没？

但是patch中修改的文件，例如cap_v4l.cpp等
我只能在out中找到他们
0ac1d8f0-227f-4250-be9e-0da2bc8b9b43-image.png

@awwwwa 好的,感谢我试试

@jacky502

&keyboard0 { key0 = <210 0x160>; wakeup-source; status = "okay"; };

注册gpio-keys 绑定键值，或者gpio-keys增加wakeup-source;

D1-H RT-Thread 官方支持

有没有指定gpio唤醒的方式呢

@awwwwa 该问题已解决，但是有新的问题

@awwwwa 大佬您好，请问您有修复过这方面的经验吗，求分享😘

@pcj203 在 f1c200s自制 win10 USB显示屏 中说：

简介
使用f1c200s tiny200s货架板+1024*600RGB屏,实现一个win10 USB显示屏。

方案原理：
host: win10加载手撸的IDD显示驱动，编码桌面成jpg，然后usb发送给f1c200s.
dev: f1c200s，接收到完整一帧jpg数据，硬解码yuv,然后软件转成rgb输出给/dev/fb0映射的ram.

b站视频链接
https://b23.tv/UDaOqCa

1.jpg
2.jpg
3.jpg
性能：

黑白模式20pfs. 彩色10fps

已知bug:

似乎f1c200s硬解jpg和usb传输有小概率性冲突。表现就是0.5%的帧解出来会花掉。

开源情况：

开发未完成。预计农历新年github上开源。

f1c200s自制 win10 USB显示屏最新的github 连接可以给出来吗？

@null037 解决了，结合论坛的 SDK 以及 github 的 SDK，补充缺失的文件就行了。

@wj8331585 支持，出现段错误可以编译一个gdb进去看看哪里错了

测试代码：

w = 1920; h = 1080; bpp = 32; SDL_Init( SDL_INIT_EVERYTHING ); SDL_SetVideoMode( w,h, bpp, SDL_HWSURFACE|SDL_DOUBLEBUF );

@alb702 add your layer and cat that file see what layer you configured

@jinxiangwzh 我V853 ddr3本来是512M 我换成了同品牌的1024M的 大小变了，我该怎么更改配置？

@alb702 感谢您提供的编码，真的。祝福您。

@nezhastu 大佬你好，请问这个问题解决了吗

@dingdong AIC600E3 is a different chip with t113-s4

@smiletiger 最后是怎么解决的

@hsinyuwang 在 D1S移植SDL1.2.15版本 中说：

@hsinyuwang 如果是移植Funkey的话

funkey已经移植完成，基本可用吧。
请问我用的tina linux为什么SDL_DOUBLEBUF不支持呢？

MQ Pro接DSI屏，打patch，编译镜像，烧写后开机，屏有背光，但运行lv_example没有显示，cat /dev/urandom > /dev/fb0也没有。查了屏的芯片是ST7701，kernel里也编了驱动。有何解决思路？

@q1215200171 你可太帅了~ 非常感谢！！！

@camperzzz V1.0打后的SDK都是正常编译的，基本非tina3.0的SDK，大多数都可以在Ubuntu20.04下正常编译了

@alb702 好的，非常感谢您的回复，我试试，用示波器抓IRQ信号。

@awwwwa 终于破案了，那个dts里面ledc的配置有个数据被我改过 wait_data_time_ns 这玩意被我改得很小，我那会测试melis的时候32个灯数据，需要刷很快，所以这个数值就不能大，一旦了，数据就错，灯乱闪，我本以为这个数值不影响DMA，但是有影响

我改回到原来那个600000 就一切正常了，DMA能用了，如果这个数值设置太小就完蛋了，只要开启了DMA，系统就直接卡死！那个ledc的手册里面肯定没写全功能！

手册里面写了这么句
wait_data_time_ns：通过该节点可设置和读取 LEDC 内部 FIFO 等待数据的时间容忍度，
范围为 80ns-655us。

我改坏掉的

&ledc { pinctrl-names = "default", "sleep"; pinctrl-0 = <&ledc_pins_a>; pinctrl-1 = <&ledc_pins_b>; led_count = <58>; output_mode = "GRB"; //trans_mode = "DMA"; dmas = <&dma 42>, <&dma 42>; dma-names = "tx", "rx"; reset_ns = <84>; t1h_ns = <800>; t1l_ns = <320>; t0h_ns = <300>; t0l_ns = <800>; wait_time0_ns = <84>; wait_time1_ns = <84>; wait_data_time_ns = <3000>; status = "okay"; };

就是那个 wait_data_time_ns 这个数值在我测试melis的时候被我改过，我以为仅仅是fifo会影响到，但是DMA模式下应该这个参数也有影响

改回来

&ledc { pinctrl-names = "default", "sleep"; pinctrl-0 = <&ledc_pins_a>; pinctrl-1 = <&ledc_pins_b>; led_count = <58>; output_mode = "GRB"; //trans_mode = "DMA"; dmas = <&dma 42>, <&dma 42>; dma-names = "tx", "rx"; reset_ns = <84>; t1h_ns = <800>; t1l_ns = <320>; t0h_ns = <300>; t0l_ns = <800>; wait_time0_ns = <84>; wait_time1_ns = <84>; wait_data_time_ns = <600000>; status = "okay"; };

大佬还有个问题想请教下
就是在tina里面能不能一口气把所有的灯的数据都设置好
然后再发送啊？
如果是
echo 1 > /sys/class/leds/sunxi_led0b/brightness

这样每改一次就要发送一次，效率太低

要同时驱动很多灯的时候 FPS就上不去啦

这要怎么处理呀

@guyuandongfang
我也遇到过类似的情况。 看题目 «V853 SDK：Linux内核中的MIPI DSI «

@sunchipv 问题已解决，是下载的字库有问题，更换另外的字库正常了

@awwwwa 收到，另外问一下大佬，tplayer和视频解码库的日志能关闭吗，这个是在哪里设置?

为了兼容卡打印的问题，UART的引脚在boot0&Uboot中初始化，如不需要卡打印可以配置上需要的引脚

AWOL 支持这些芯片，提供SDK下载

508a68b1-39ed-43e3-93ae-979221e8f2ab-image.png

参考 https://www.aw-ol.com/docs 中的文档下载

其他芯片需要联系你购买商家的客服或者代理获取

更改完需要重新执行

@fuzhikun TINA系统有A133/R818的兼容的

@whycanservice 感谢大佬，改了这个，就能用了

sorry for your spent time. Thank you!

抱歉佔用您的時間。 謝謝你！

https://v853.docs.aw-ol.com/study/study_3getsdktoc/

@fuzhikun A33有Tina3.5，联系代理获取

短接PB2到GND强制进入下载模式

我决定从结论3开始：在uboot中初始化DSI接口和面板。 有用。

@wupaul2001 大哥，你是用Tina系统吗？

@leomini5 密切关注

@lyg116 很有帮助 ..

使用dma模式搬运数据，需要打上如下补丁：

ledc在dma模式的代码存在问题，已修复该问题，ledc的dma通道之前也没有支持，需要添加上

解决了，主要是晶振搞错了。要焊接40M的 有源晶振。

@awwwwa Hello, I'm using a TinyVision Board, follwing the steps from here: https://tinyvision.yuzukihd.top/#/?id=下载-awol-tina-linux-bsp selecting V851se-tinyvision-tina

82fd08ae-1143-416b-8129-f52123d6ba93-image.png

After flashing the image on the SD card this is the result:

db3aad59-7aba-47cc-a4e3-e52716f5c1e1-image.png

But if I flash the SD Card with the pre-build image downloaded from the github repository, it works allways.

9466cd6a-80da-4b06-a5b0-c1f7eaf2b676-image.png

Please help to find a solution,

Thanks for your answer!

@chen0505 PA引导是BROM不支持，BROM是固化在芯片里的，如果需要修改需要改版芯片

@amturing 在 D1s的芯片手册 中说：

希望能帮到你
F133_User_Manual_V1.0.pdf
F133_Datasheet_V1.0_whycan.pdf

请问这个f133的手册也能用于D1么？

@leomini5 VE是编解码器

@xiaowenge 设备树可以配置默认的背光亮度

问题已解决，感谢大佬

已解决
实际经验是：
在小机端执行 passwd root,设置密码
将小机端的 /etc/passwd
拉出来放到源码target/allwinner/v851se-perf1/busybox-init-base-files/etc/目录下
将target/allwinner/v851se-perf1/busybox-init-base-files/etc/inittab
修改为 /dev/console::respawn:-/bin/login

@bigfly 你找到合适的方案了吗？我想做个摄像头采集图像加LCD显示，图像缩放，不知道哪颗性价比高

@dort91011 佬，你这个调通了吗？想找你交流一下416567819

@liefyuan 我也遇到类似情况了，您emmc用的sdc2吗？能看看这部分原理图吗和设备树配置吗？不知道是不是我硬件搞得有问题了

@proc_c

执行这三条命令之后再make看看，应该能解决问题：

rm -rf out rm .config make distclean

之后执行 make 编译。
