F1C200s作为主机，8266作为SPI从机，注册SPI从设备的时候，进入probe函数，如下，调用了如下函数：

err = sif_spi_protocol_init(spi); //发送一堆指令

probe函数：

static int esp_spi_probe(struct spi_device *spi) 
{
    int err;
    struct esp_pub *epub;
    struct esp_spi_ctrl *sctrl;
    static int dt_get_n=1;
    if(dt_get_n > 0 ) {
        esp8089_get_dt_data(spi); // 获取设备树信息
        dt_get_n--;
    }

    printk("esp8089_spi: %s ENTER\n", __func__);

        //esp_dbg(ESP_DBG_ERROR, "esp8089_spi: %s enter\n", __func__);

/* -------------------------------------------------------------------------- */\
    printk(KERN_ERR "esp8089_spi: %s Set CS LOW\n", __func__);
    gpio_request(esp_cs0_pin, "esp_cs0_pin");// #include "spi_stub.c"
    gpio_direction_output(esp_cs0_pin,0);
    gpio_free(esp_cs0_pin);
	err = esp_setup_spi(spi); //分配一些内存，设置参数

	if (err) {
		esp_dbg(ESP_DBG_ERROR, "esp8089_spi: %s setup_spi error[%d]\n", __func__, err);
        if(sif_sdio_state == ESP_SDIO_STATE_FIRST_INIT)
			goto _err_spi;
		else
			goto _err_second_init;
	}
	//esp_dbg(ESP_DBG_ERROR, "esp8089_spi: %s init_protocol\n", __func__);

/* -------------------------------------------------------------------------- */

	err = sif_spi_protocol_init(spi); //发送一堆指令
......

但是这个sif_spi_protocol_init函数，是通过spi向8266发送指令，而且的确有收到8266的返回指令。这里我有几个疑问：
1.发送的这个是什么指令?
2.代码运行到此处，还没有下载固件，为什么8266可以响应spi指令？
3.8266手册上讲，8266作为spi从机，协议是Command（8Bits）+address（8Bits）+read/write data（32Bytes），也就是34个字节，为什么这里只有6个字节？
恳请大佬不吝赐教！感谢！

大佬们,求救啊!!!

参考这个链接修改设备树, RGB屏幕可以显示, 但是我想把这个项目当做面试项目, 因此研究一下原理.
https://blog.csdn.net/GJF712/article/details/126446054
这个驱动用到DRM驱动的一些东西,　也生成了card0节点,　但是看设备树又不符合DRM驱动框架,　比如没有crtc encoder plane　connector信息, 请问这个链接用的是DRM驱动吗？原理是什么？如果可以尽量详细一些, 谢谢大家, 谢谢大佬 !!!

下面是ChatGPT的解释,不知道是否正确 :

我们来详细分析一下代码中的各个部分。

display-engine：描述了显示引擎，这是 F1C100s 处理器中的一个重要组件，用于处理图像数据。它与显示前端（display-frontend）和显示后端（display-backend）相连接。

tcon0：代表了时序控制器（Timing Controller，简称 TCON），它负责生成正确的时序信号，以驱动显示面板。这部分代码中，我们可以看到 TCON 的寄存器地址、中断号、时钟和复位信号等信息。此外，还定义了输入和输出端口，分别连接到显示后端和显示面板。

lcd_rgb666_pins：定义了与 RGB 屏幕连接的引脚，这里使用了 18 位的 RGB666 接口。

display-frontend 和 display-backend：显示前端和显示后端分别负责图像数据的预处理和后处理。显示前端接收原始图像数据，对其进行缩放、色彩空间转换等操作；显示后端则负责图像数据的合成、alpha 混合等功能。这两个部分通过端口和端点（endpoint）进行连接。

panel：描述了显示面板。这里使用了一个兼容于 "alientek,alientek_4p3_inch" 和 "simple-panel" 的面板。面板的输入端口与 TCON 的输出端口相连接。

reg_vcc3v3：描述了一个固定电压的电源，为面板提供 3.3V 电源。

最后，在设备树的末尾，启用了 be0（显示后端）、de（显示引擎）和 tcon0（时序控制器）节点。

从这段代码中可以看出，该 RGB 屏幕驱动确实使用了 DRM 框架。其工作原理大致如下：

显示前端接收原始图像数据，进行预处理。
处理后的图像数据传递给显示后端，进行后处理和合成。
处理后的图像数据通过 TCON 生成正确的时序信号，驱动显示面板。

@whycan 在 F1C200s类似正点原子驱动开发指南的资料？中说：

@kashine

这个代码风格和正点原子接近: https://item.taobao.com/item.htm?id=589639202997 (没有PY关系, 三思再下手)

里面有教程吗？比如说某个驱动，有没有对应的教程文档，分析驱动原理与代码？谢谢晕哥

kashine

感觉对于F1C200s的驱动的了解，仅限于跟着坑网的大佬操作，对于原理或者源码基本不太了解。所以想问一下各位大佬们，有没有F1C200s类似于正点原子驱动开发指南那样详细讲解驱动开发的资料？如能分享，不胜感激！

kashine

@whycan 好的，感谢晕哥

kashine

@whycan 晕哥，那我使用arm-linux-gnueabi-就可以了是吧？

kashine

最近准备使用ESP12F完成F1C200s的无线网卡，但是第一步就卡住了。

/-----------------------------------------疑问：为什么使用arm-linux- --------------------------------/
参考链接1：https://github.com/notabucketofspam/ESP8089-SPI.git

参考链接2：https://www.cnblogs.com/twzy/p/15160808.html

/----------------------------------------------------求解------------------------------------------------/
对于F1C200s不应该是arm-linux-gnueabi-这个交叉编译器嘛？怎么他们用的是arm-linux-，而且都能编译通过，而我的报错，提示：

make[1]: arm-linux-gcc: Command not found

@whycan 晕哥牛逼，谢晕哥

kashine

@whycan 晕哥，你看可以这样理解吗？

在满足条件的情况下，使用这个工具可以将文件下载到RAM、Flash或者TF卡中。
在没有Flash的情况下使用该工具进行调试，有两个选择：RAM 或 RAM+TF卡。
在第2点中使用RAM调试（无TF卡、Flash），能否调试Debian根文件系统，因为Debian最小180M，内存只有64M？

非常感谢晕哥的答疑解惑！！！

kashine

-----------------------------------------网上资料-------------------------------------
https://blog.csdn.net/p1279030826/article/details/112719638
全志进入 fel 模式的条件（三种方式）：

TF卡和 spi flash 同时没有可启动镜像
即不插卡，且焊接的是新的或者没有有效镜像的spi flash，上电就会自动进入fel下载模式。
TF卡中有进入fel模式的特殊固件 fel-sdboot.sunxi
如果spi flash已经有了启动镜像，那么需要在TF卡中烧入一个sunxi提供的启动工具 , 那么插入该TF卡启动会进入fel模式；
命令：dd if=fel-sdboot.sunxi of=/dev/mmcblk0 bs=1024 seek=8上电时SPI_MISO拉低到地
该引脚为boot引脚，上电时如果为低电平即会进入fel下载模式。

-----------------------------------------我的理解--------------------------------------

1.sunxi-tool工具将文件下载到RAM中；
2.sunxi-fel是sunxi-tool工具的指令？

-----------------------------------------我的疑问--------------------------------------

对于F1C200s使用该工具，需要PE2上拉做USB　device模式嘛？
每次上电都需要重新下载uboot、zImage、dtb、rootfs嘛？
对于只有64MDDR1内存的F1C200s来说（无交换分区），无法跑Debian？

kashine

@whycan 好吧，只能到这了，谢晕哥

kashine

@whycan 晕哥，我看了一下你发的这个帖子，我就是按照这个拉取的Debian系统文件。

Debian根文件系统是armel类型；
内核使用的是arm-linux-gnueabi编译器；
tslib编译也是使用的arm-linux-gnueabi。

即使这样在Debian文件系统中仍然会报错“Illegal instruction”。

armhf (支持硬件浮点)
armel (软浮点)

kashine

@whycan 好的好的，谢谢晕哥

1.首先下载源码：

tslib-1.21.tar.bz2，使用的版本为tslib 1.2.1

2.修改源码所属用户为当前用户

sudo chown project01:project01 tslib-1.21 -R

3.ubuntu下工具安装：

sudo apt-get install autoconf 
sudo apt-get install automake 
sudo apt-get install libtool

4.编译tslib：
首先在源码外创建一个结果保存目录tslib，然后输入以下指令编译tslib：

cd tslib-1.21/   
./autogen.sh     
./configure --host=arm-linux-gnueabi --prefix=创建的保存编译结果的目录路径（绝对路径）   
make  
make install

5.拷贝到根文件系统：
进入结果保存文件夹tslib下，其中bin目录下是可执行文件，包括tslib的测试工具，etc目录下是tslib的配置文件，lib目录下是相关的库文件。将所有编译结果拷贝到根文件系统下。

sudo cp * -rf /你的根文件系统路径 -d
6.环境变量设置：

sudo vi ./etc/profile # 不要设置你Ubuntu的环境变量

输入以下内容：

export TSLIB_TSDEVICE=/dev/input/event0 # 触摸设备根据具体情况修改 
export TSLIB_CALIBFILE=/etc/pointercal 
export TSLIB_CONFFILE=/etc/ts.conf 
export TSLIB_PLUGINDIR=/lib/ts 
export TSLIB_CONSOLEDEVICE=none 
export TSLIB_FBDEVICE=/dev/fb0

7.上电启动：
使用ts_calibrate命令进行校准。
使用ts_test_mt命令进行触摸测试即可。

--------------------------------上电启动报错----------------------------
在Debian文件系统下报错：Illegal instruction；
在buildroot制作的根文件系统下报错-sh: “-sh: ts_csalibrate: not found”。

----------------------------------详细描述-------------------------------
很奇怪的是，我在正点原子的阿尔法开发板上使用上面的方法，可以正常进行测试。但是在F1C200s上面，使用Debian根文件系统会报错：“Illegal instruction”，在buildroot制作的根文件系统上会报错：“-sh: ts_csalibrate: not found”。有朋友知道是什么原因吗？

----------------------------------附加描述-------------------------------
注：根文件系统制作完成后移植的tslib；正点原子阿尔法（IMX6U）移植使用arm-linux-gnueabihf编译器，F1C200s使用的arm-linux-gnueabi编译器。

----------------------------------请求-------------------------------
哪位大佬帮指导下，或者有编译好的可以在F1C200s运行的tslib触摸测试库文件，方便的话可以发我一下，非常感谢。

kashine

@whycan 好的晕哥。

如题，使用F1C200s，uboot、kernel、rootfs启动正常。使用的屏幕为40Pin RGB 800*480屏幕。

使用Linux5.2主线内核修改设备树和sun4i_tcon.c、sun4i_drv.c、sun4i_backend.c以及panel_simple.c文件后可以正常点亮屏幕，输出内容正常，可以正常看到logo。

在使用Linux5.7.1内核使用同5.2版本一样的设备树，对以上文件做同样的修改后，上电白屏，网上没有5.7.1版本的教程，特来求助。两个版本的启动log如下：
