非常不错，大佬威武！！！

😩 建议使用 Linux 编译环境，windows 编译环境太慢了，一个工程编译下来要七八分钟

@kevin_allwinner 一般通用驱动就能满足大部分需求，如果有特殊功能则需要使用专用PHY驱动

@fanhuacloud 大佬ap配网可以使用吗

@fanhuacloud 谢谢大佬

@siguadao 请问下，楼主最终成功了吗

@randolph 等待

@chzfmx 我按照上面的说法，修改了一下，MAC地址固定了，但不知道合理不

@leomini5 这个我自己解决了……不是驱动的锅

@leomini5 这个问题我解决了，不是驱动的锅，是内核其他驱动的锅

@godzhou0909 兄弟你好，你的cvbs功能调通了吗？能在lcd上显示cvbs摄像头的图像吗？

SPI Flash虚焊导致的问题

@xh_timmo 问题解决了，就是多等等，多等等，就好了

@y97788 在 ubifs卷挂载问题 中说：

ubiupdatevol /dev/ubi0_1 boot-resource.fex
这样可以修改整个卷的数据，但是如何修改boot-resource.fex里bootlogo.bmp，或者如何将新的bootlogo.bmp打包生成boot-resource.fex文件，然后再用上面命令来更新卷数据

你好，我也碰到了这个问题，请问你解决了吗

您好，论坛的那个文章，最后一步要传哪些文件到开发板上？

@vc915813805 内核和uboot同时配就好了，显示logo要uboot那边就初始化屏幕

@fanfan 在 移植RTL8811驱动编译报错，sw_usb_disable_hcd、script_parser_fetch、sw_usb_enable_hcd函数没找到 中说：

博主这个咋解决的啊

@story_xjj 请问解决了吗，我也遇到同样问题

@fanhuacloud 我也遇到这个，以后执行ls -al就行了

@cfxcfx
进入sunxi_gpadc.c文件中，删除以下代码中的 |BIT_MASK(EV_REP)

switch (id) { case GP_CH_0: #ifdef CONFIG_ARCH_SUN8IW18 case GP_CH_3: input_dev->evbit[0] = BIT_MASK(EV_KEY); #else input_dev->evbit[0] = BIT_MASK(EV_KEY)|BIT_MASK(EV_REP); #endif for (i = 0; i < KEY_MAX_CNT; i++) set_bit(sunxi_gpadc->scankeycodes[i], input_dev->keybit); break;

应该是，我去试验一下。

@nideyida 这个chipid的长度有多少。

IMG_7075.jpeg 我的是播几秒就死了

@shz18877605430 报错是使用呢CSI 不是MIPI-CSIS

@livpo 哦哦，谢谢！

CKLINK JTAG仿真器。

@coder9527 新手向大佬学习👍 👍

mark 一下。

是否是两个屏幕，分别用独立的 LCD 控制器驱动？

有详细步骤么，我DVP摄像头调试不出来，找不到设备，摄像头用的是OV2640

@maplerian 是的没错，感谢提醒

@caoniu 应用不需要修改，gpio相关控制由控制器实现，上层不需要关系

@maplerian

CS翻转问题请检查下逻辑分析仪的触发电平是否设置的太低？ CLK不匹配问题，请看下CCU中SPI相关的寄存器与软件设置的值是否有差异？或者用hal_ccmu打印当前时钟源信息看看SPI是哪个时钟源，频率是多少？

使用spidev-test测试命令的-s参数可以调整spi速率

Usage: ./spidev_test [-DsbdlHOLC3vpNR24SI] -D --device device to use (default /dev/spidev1.1) -s --speed max speed (Hz) -d --delay delay (usec) -b --bpw bits per word -i --input input data from a file (e.g. "test.bin") -o --output output data to a file (e.g. "results.bin") -l --loop loopback -H --cpha clock phase -O --cpol clock polarity -L --lsb least significant bit first -C --cs-high chip select active high -3 --3wire SI/SO signals shared -v --verbose Verbose (show tx buffer) -p Send data (e.g. "1234\xde\xad") -N --no-cs no chip select -R --ready slave pulls low to pause -2 --dual dual transfer -4 --quad quad transfer -8 --octal octal transfer -S --size transfer size -I --iter iterations

知道了，cd到对应的目录下，mm就好了

后来发现 我插入鼠标有反应，说明系统已经起来了，控制台却无法使用，boot和内核都能打印，应该不是这两个地方的问题，猜测是文件系统配置的问题，进入SDK /tina-d1-h/target/allwinner/d1s-nezha_nor/base-files/etc下的inittab 文件:ttyS0::askfirst:/bin/ash --login 控制台串口并没有改过来，改为ttyS3就能进入系统了。

发一个TF卡测试固件：t113_i_linux_nezha_auto_uart0(XR829热点).img

问题已解决
在设备树的disp里增加参数
fb0_buffer_num = <2>;
要使用G2G 加速和G2D 旋转 要先开双缓

@jr_online 你好，有修改成功吗，按照上面修改会报错 ：

@leomini5 谢谢 OK了

@awwwwa 大佬，我执行 mboot 的时候显示 boot0 和 uboot 都编译成功的，那是要怎么操作呢？

@lyg116 EMMC大概率支持，但是也有小部分是需要适配的

@liker292 在服务器里面执行 make -v看看

@lyg116 自带fbviewer的

@lyg116 微信he1157173310

@dsp2000 通过 Zadig 工具 把 "USB Device(VID_1f3a_PID_efe8)" 编辑名称为 "Allwinner SoC in FEL mode" 就行了。

@whycan 在 D1s 如何使用TVIN1作为输入源？ 中说：

@meihao
不是 0x10吗？

在这里也能看到晕哥
感谢晕哥对各位小伙伴的支持
我还需要水一个帖子，升级到LV2拉取SDK

但是到目前为止，我还没确定选D1S还是T113 S3?

@fanhuacloud 谢谢大佬

@awwwwa 了解了, 非常感谢

@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;

请贴出LOG，截图

@lyg116 已更换镜像解决结贴

@whycanservice 感谢！

@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？

@awwwwa 该问题已解决，但是有新的问题
b39e16d8-fbb8-4171-9bd5-ecd04d6b4216-047b929afa3b8f2b370ee53b0aa032e.jpg
这个色彩是黑白色，换过多个摄像头，都是黑白色

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？

@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

@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?

更改完需要重新执行

@whycanservice 感谢大佬，改了这个，就能用了
