楼主，看了您适配了屏幕ili9341，请教内核和设备树是如何配置的呢？

您可以移植建议您用linux 5.10内核，新唐官方有为nuc980提供的，您可以看下视频：

大佬好，我正在学习这个片子的开启设备树的功能，不得要领，内核启动失败，大佬是否方便分享下，uboot环境文件具体内容和Nuwrite中烧写各个映像文件的具体地址？万分感谢。

我做过几期的nuc980的设备树视频，不知是否对您有用：https://space.bilibili.com/33499294/channel/seriesdetail?sid=2262881

大佬好，请问下，您的led0的设备树中：
gpios = <&gpio 0x20 1>;
里面的0x20代表的哪个引脚，谢谢大佬
另外请问大佬，后面的1是什么意思？

@romanljw
我也是参考了这个大佬的文章进行配置的， A31我也打开了，但是我现在完全没有fbtft的信息输出。

linux kernel 如果是4.x的话我记得好像不用改gpio的获取方式这些，直接把初始化部分改掉就可以了，但是5.16的话需要按照大佬的方式把gpio申请这些都改掉。其他版本我没有试过

1. 要根据不同厂家的初始化代码，修改drivers/staging/fbtft/fb_st7789v.c中的static int init_display(struct fbtft_par *par)函数的初始化代码，尽管都是st7789，但是不同店家的初始化代码不一样，会出现颜色错误的问题。
2. 设备树我也是这么配的，但是不知道你的kerel中开启了spi没有，由于FC1000S的SPI中有一个BUG，因此我们在开启SPI驱动的时候必须选择A31（Device Drivers -> SPI support），并且kernel中7789的驱动也要编写进去。
3. 即使没有链接屏幕，但是启动的log中也是有fbtft的信息的，我这里显示如下：

[    0.933460] fbtft_of_value: width = 240
[    0.937440] fbtft_of_value: height = 320
[    0.941393] fbtft_of_value: buswidth = 8
[    0.945324] fbtft_of_value: debug = 0
[    0.949058] fbtft_of_value: rotate = 0
[    0.952829] fbtft_of_value: fps = 30

4. 硬件接线我是这么接的：
LCD -- F1C
SCL -- CLK
SDA -- MOSI
RES -- PE9
DC -- PE4
CS -- CS
BLK -- 空
5. 推荐参考大佬的设置：
https://www.cnblogs.com/twzy/p/15160836.html
6. 其他的我不懂了

@狼狼
您好，我按照您的方法，系统没有认出w5500芯片，我使用的是linux 5.7的系统，debian 10.0的rootfs，请问您知道是什么原因吗？

我试了下w5500在linux 4.15版本下就可以用，相同的配置在linux 5.7下就不能用，请问大佬们是什么原因？

大佬们好，小白想向大家请教两个个问题。
问题1：
我想通过F1C100S的SPI接口与外部MCU进行通讯（初步想用python的spidev库完成通讯）。使用的是Deiban的bullseye系统。但是我在dev下面没有找到网上说的spi0.0或者类似的设备，但是在/sys/class/spi_master下面有spi0和spi1，请问是不是这两个。如果不是请问我应该如何配置，麻烦啦，谢谢大家。
我对设备树的配置如下，请大家过目：
dtsi文件中：

      
               spi0:spi@1c05000 {
			compatible = "allwinner,suniv-spi", "allwinner,sun8i-h3-spi";
			reg = <0x1c05000 0x1000>;
			interrupts = <0xa>;
			clocks = <&ccu CLK_BUS_SPI0>, <&ccu CLK_BUS_SPI0>;
			clock-names = "ahb", "mod";
  			resets = <&ccu RST_BUS_SPI0>;
			status = "disabled";
			#address-cells = <1>;
			#size-cells = <0>;						
		};

		spi1:spi@1c06000 {
			compatible = "allwinner,suniv-spi", "allwinner,sun8i-h3-spi";
			reg = <0x1c06000 0x1000>;
			interrupts = <0xb>;
			clocks = <&ccu CLK_BUS_SPI1>, <&ccu CLK_BUS_SPI1>;
			clock-names = "ahb", "mod";
			resets = <&ccu RST_BUS_SPI1>;
			status = "disabled";
			#address-cells = <1>;
			#size-cells = <0>;
			//bias-pull-up;			
		};

  
                        spi0_pins: spi0-pins{
				pins = "PC0", "PC1", "PC2", "PC3";
				function = "spi0";
			};

			spi1_pins: spi1-pins{
				pins = "PA2","PA0","PA3","PA1";
				function = "spi1";
			};

dts文件中：

  
&spi0{
	pinctrl-names = "default";
	pinctrl-0 = <&spi0_pins>;
	status = "okay";
};

&spi1{
	pinctrl-names = "default";
	pinctrl-0 = <&spi1_pins>;
	status = "okay";
};

另外，我看到V3S的spi（https://www.kancloud.cn/lichee/lpi0/580147）是在设备树中加入：

&spi0 {
        pinctrl-names = "default";
        pinctrl-0 = <&spi0_pins>;
        status = "okay";
        #address-cells=<1>;
        #size-cells=<0>;
        spidev@0x00 {
                compatible = "spidev";
                spi-max-frequency = <100000000>;
                reg = <0>;
        };
};

我也尝试将dts文件做了相同修改：

&spi0{
	pinctrl-names = "default";
	pinctrl-0 = <&spi0_pins>;
	status = "okay";
	spidev@0 {
		compatible = "spidev";
		spi-max-frequency = <1200000>;
		reg = <0>;
	};
};

&spi1{
	pinctrl-names = "default";
	pinctrl-0 = <&spi1_pins>;
	status = "okay";
	spidev@0 {
		compatible = "spidev";
		spi-max-frequency = <1200000>;
		reg = <0>;
	};
};

但是启动后从[ 0.927711]开始报错：

可是观察dev下确实有了spidev0.0，spidev1.0。请问这样是否可以正常使用？
问题2：
在上面打出的log中有一句[ 20.043316] rndis_host 1-1:1.0 enxac4bb3b9ebe5: renamed from eth0
请问下为啥系统会自动把我的eth0网卡重命名为enxac4bb3b9ebe5。我想要eth0，不想改名，请问应该如何处理。
我用的合宙的air724ug的4G模块，通过usb连接。网络使用正常。
请大家帮忙，在此拜谢。

各位大佬，请问下应该如何打开swap，小白一个见笑了

romanljw · 全志 SOC

你的f1c100s芯片上全部电源都上了吗？之前我也遇到相同问题，不开usb一切正常，开了usb芯片不断重启（ https://whycan.com/viewtopic.php?id=7279 ），后来我把芯片的全部电源都弄上就没在出现这个问题。之前图省事觉得3V电源音视频的，不用就不要了，后来补上就OK了

romanljw · 全志 SOC

已经解决了，换了一个版本的buildroot就可以了

romanljw · 全志 SOC

各类大佬，小弟遇上一个问题，使用荔枝派nano，自己构建系统：
1. bootloader用的官方的；
2. 系统用的是主线linux 5.7内核
3. buildroot使用的是2021.02.04版本
在buildroot中打开了python3，但是使用的时候进入python3执行import sqlite3显示：
ModuleNotFoundError: No module named 'sqlite3'
不知道是什么原因，请大佬看看如何解决？
附buildroot中python3的配置：

血的教训啊，一定要连上的。我之前遇到设备树开启usb后无法启动的问题（传送门： https://whycan.com/t_7279.html ），后来把电源连齐全了，一切都好了。

romanljw · 全志 SOC

这里的是启动时候显示的，反复重启，这里我只粘贴了重启一次的代码，后面始终重复。还请大佬们受累帮忙分析下

@阿黄
我后来把它改成独立供电了，还是重启。T_T

哇酷小二说：

F1C 重启吗？
F1C 重启先检查电源问题，这个很重要。

我不开启usb的情况下，就不会重启，每次一使能usb就出现反复重启的情况了。感觉不是电源的问题。

各位大佬，有个问题希望大家指教。
我想使用F1C100S中usb直接连接合宙Air724模块，模块如下所示：

我想实现的功能是合宙与F1C100s通过usb在板子上布线直接连接。
我的原理图的usb部分是这么画的

实际做出来是这样的：
.png
我是用的是论坛中大佬提供的支持usb的linux5.2内核的代码，但是发现下载到tf卡启动后，当上电加载内核的时候，反复重启，我想是不是可能跟PE2的接线问题有关（这个PE2我看很多原理图上都连接到usb接口的usb_id上。但是我的板子和合宙模块是直接拉线连接的，没有usb_id)
我在测试的时候，把PE2也尝试了直接接地，但是依旧在加载到内核的时候反复重启。不知道大佬们能不能指导下，应该如何修改。
在此谢过了。
另外，我做好的linux系统直接下载到licheepi nano上没有问题，初步觉得可以排除软件的问题。
还请大家指教，再次谢过

请教下，为啥我下载了5.2的linux，使用make后没有编译设备树？
