Hi,求助licheepi Zero 液晶的问题

大家号,我按照下面步骤,内核也引导成功了,但是驱动不了屏幕,不知道咋回事,大侠帮忙看看我哪里出问题了

主线Linux
    git clone https://github.com/Lichee-Pi/linux.git -b zero-4.13.y

        生成荔枝派Zero 默认配置文件: CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm make licheepi_zero_defconfig
        设备树文件(默认不需要修改):  arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dts
        编译内核:     make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j4
        编译设备树: make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- dtbs
Uboot
    git clone https://github.com/Lichee-Pi/u-boot.git -b v3s-current
    ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make LicheePi_Zero_800x480LCD_defconfig
    ARCH=arm make menuconfig   
    ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4
跟文件系统
    buildroot-2017.08.tar.gz

Ubuntu14.05 工具链使用的是内置的  arm-linux-gnueabihf- gcc version 4.8.4 (Ubuntu/Linaro 4.8.4-2ubuntu1~14.04.1)
包括rootfs也是使用的这个工具链

然后
1.将u-boot-sunxi-with-spl.bin   dd到8k偏移处
2.将zImage和sun8i-v3s-licheepi-zero-dock.dtb拷贝到第一个fat16分区
3.将跟文件系统解压到第二个ext4分区

有启动,屏幕没反应。
然后我修改这些参数CONFIG_VIDEO_LCD_MODE="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"
屏幕没有任何反应啊

Re: Hi,求助licheepi Zero 液晶的问题

另外,我看到 arch/arm/boot/dts 目录下关于Lichee Zero的dtb有好几个,为什么用dock这个,这几个dtb有什么区别吗?

sun8i-v3s-licheepi-zero-dock.dtb

Re: Hi,求助licheepi Zero 液晶的问题

匹配液晶是修改这个吗?
CONFIG_VIDEO_LCD_MODE="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"

感觉修改了一点用也没有

Re: Hi,求助licheepi Zero 液晶的问题

现在是背光不亮, 还是屏幕无显示, 或者屏幕显示杂乱?

Re: Hi,求助licheepi Zero 液晶的问题

我是自己画的板子,我强制让背光有输出,并没有使用Zero的硬件驱动
屏幕是全白,没有任何反应,使用 cat /dev/zero > /dev/fb0   cat /dev/urandom > /dev/fb0 也没有反应

但使用站长的TF bin文件,能显示一部分发虚的图像,依稀可辨
