@HongSang
建议把dtb和zImage读到内存之后，再校验一次crc32，确认数据没有问题。
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
label = "u-boot";
reg = <0x000000 0x100000>;
read-only;
};
partition@1 {
label = "kernel";
reg = <0x100000 0x500000>;
read-only;

};
partition@4 {

reg = <0x4000000 0x3000000>;
};
};现在问题是我不知道如何将dtb和rootfs读进nand分区，那么读到ddr分区也不知道它的<address>， 这个分区在设备树中这样定义的

晕哥我再请假下 这里的<address>是指烧入分区的起始地址吗？就是在如下设备树中的定义的 reg?
例如烧写uboot xfel spinor write 0x000000 u-boot.bin
烧写dtb xfel spinor write 0x100000 .dtb
烧写zImage xfel spinor write 0x110000 zIamge

不行 颜色显示不对，另外屏幕有些花边 由panel生成的/dev/fb1可以控制

达克罗德 说：
我记得是uboot配置的，Linux没有去配置
linux源码里我配置了/driver/gpu/drm/panel/panel-simple.c一个屏幕，并且设备树里panel节点引用了这个屏幕.但是现在屏幕颜色不对 感觉颜色还是888
linux里实在找不到修改的地方了，在uboot menuconfig配置的时候看到了ARM architecture ‣ Enable graphical uboot console on HDMI, LCD or VGA这里设置了x:800,y:480,depth:18,pclk_khz:33000,le:87,ri:40,up:31,lo:13,hs:1,vs:1,sync:3,vmode:0这一行参数，感觉这里屏幕的rgb初始化是在uboot完成的。https://blog.csdn.net/b7376811/article/details/112525402
请问您在uboot哪里配置rgb相关的参数

1、设备树里的LCD这组引脚是如何传参的，定义的顺序是什么
lcd_rgb565_pins: lcd-rgb565-pins {
pins = "PD0","PD1", "PD2", "PD3", "PD4",
"PD5", "PD6", "PD7", "PD8", "PD9",
"PD10", "PD11", "PD12","PD13", "PD14",
"PD15", "PD16", "PD17", "PD18", "PD19",
"PD20", "PD21";
function = "lcd";
};2、RGB的初始化是否需要uboot里面配置？和设备树无关

@HongSang
对， 时序就是 panel-simple 里面配置，参考 aodzip 那个 sdk即可，示波器检测到 PCLK, VSYNC, HSYNC 理论上屏幕显示就稳了。
晕哥，对panel的配置是否需要在uboot里配置？看到了如下链接

https://whycan.com/t_5873.html#p58350
uboot里按照荔枝派官方文档会配置uboot的 Enable graphical uboot console on HDMI, LCD or VGA 这里也会用到simplefb的配置。。是否需要修改呢

@哇酷小二
还是一样，cat /dev/urandom > /dev/fb0或者fb1没有反应 都没有出现雪花或者黑屏 cat: write error: No space left on device
现在还是两个fb设备 第一个是spi节点下的st7701s 生成的fb0，第二个是panel节点改地simple-panel和之前一样。
感觉是不是驱动的流程有问题，spi总线下是一个fb panel节点又是一个fb 两个没有关联？

但是现在有个问题就是之前我的屏幕
设备树下：
panel: panel {
compatible = "lg,lb070wv8", "simple-panel";
//compatible = "sitronix,st7701s";
#address-cells = <1>;
#size-cells = <0>;
enable-gpios = <&pio 4 6 GPIO_ACTIVE_HIGH>;
port@0 {
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
panel_input: endpoint@0 {
reg = <0>;
remote-endpoint = <&tcon0_out_lcd>;
};
};
};会生成/dev/fb0设备
而之后我spi1节点下挂载的st7701s（使用的驱动文件是/driver/staging/fbtfb/fb_st7701s.c）使用的fbtfb驱动会生成新的/dev/fb1设备
设备树：
&spi1 {
compatible = "spi-gpio";
pinctrl-names = "default";
pintrcl-0 = <&spi1_pins_a>;
status = "okay";
spi-max-frequency = <3000000>;
num-chipselects = <1>;
//#address-cells = <0x1>;
//ranges;
gpio-sck = <&pio 0 1 0>;
gpio-mosi = <&pio 4 9 0>;
gpio-miso = <&pio 4 10 0>;
cs-gpios = <&pio 0 0 0>;
//led-gpios = <&pio 4 5 GPIO_ACTIVE_LOW>;
bias-pull-up;
st7701s@0 {
status = "okay";
compatible = "sitronix,st7701s";
reg = <0>;
spi-max-frequency =<3000000>;
//rotate =<90>; //屏幕旋转90度
spi-cpol;
spi-cpha;
rgb; //颜色格式RGB
fps =<30>;
buswidth =<9>;
reset-gpios=<&pio 4 5 GPIO_ACTIVE_HIGH>;
dc-gpios =<&pio 4 2 GPIO_ACTIVE_HIGH>;
debug =<1>; //调试
};现在如果我把panel这个"lg,lb070wv8", "simple-panel";节点注释掉的话，或者修改/drivers/gpu/drm/panel/panel-simple.c下lg,lb070wv8这个函数里的一些参数(比如把800x480修改成480x480)，屏幕并不会显示我上面的黑白格demo。
所以我接下来的设备树该怎么使用，继续使用spi下面的st7701s节点还是在panel节点中添加st7701s驱动？

论坛的各位大哥们,小弟最近在f1c100s上调st7701s这个LCD驱动芯片,由于荔枝派的源码里没有/driver/staging/fbtfb/fb_st7701s.c驱动,所以仿照fb_st7789v.c修改了一个st7701s,只修改了 init_display()里面的初始化和一些匹配名字.spi总线使用的gpio模拟的.linux自带的spi-gpio.
个人的理解是 st7701s芯片挂载到gpio模拟的spi总线下面.然后使用spi总线通讯使芯片初始化并刷进去LCD参数,之后在使用fbfbt驱动生成fb设备.现在这个流程似乎都走通了...但是驱动的加载有些问题
问题描述:
现在设备开机能生成fb1设备,gpio模拟的spi的时钟和数据位也能收到波形(看data位的数据应该是不对的), 屏幕没有亮.
分析是st7701s驱动的问题.想请教下是不是仿照的/driver/staging/fbtfb/fb_st7701s.c驱动的原因.还有一个问题dmesg看到spi总线加载的log是使用的8bit.应该怎么样设备才能使用到9bit???是要在spi-gpio里设备还是st7701s驱动里会使用的9bit写入(比如 init_display()里的write_reg函数)
还有一点疑惑的是这两个驱动文件的区别是什么该用哪一个修改....
drivers/staging/fbtft/fb_st7789v.c
drivers/gpu/drm/panel/panel-sitronix-st7789v.c
请教下大佬们,我在源码里使用哪份驱动文件让st7701s芯片初始化.小弟卡在这好几天没有进展,现在脑子晕乎乎的....
请求指导 感动常在!
