overlayfs挂载除了overlay文件夹还要依赖其他文件夹，比如upper、workdir。光看根目录下是有overlay文件夹可能不行。。。。。。

帖子里提到的将根文件系统改为ext4格式和修改代码两种方式应该都可以正常挂载

或者您要是想手动格式的话，也可以在电脑上进行格式化，找u盘最后一个分区进行格式化
类似mkfs.ext4 /dev/sbd8

设备上格式化应该也可以，但是可能不能自动挂载，可能需要重启一下

suncw

@casojie
overlayfs挂载失败是因为分区没有格式化，分区挂载失败，只读文件系统没法创建必要的文件夹，最终导致overlayfs挂载失败的吧

这个帖子里好像有挂载的方法
芒果d1h用sd卡烧录后创建文件夹一直Read-only file system

是自己写了个ko吗？是不是需要自己写Makefile才能编译？

我自己写ko的Makefile如下，不知道有没有帮助

obj-m += xxx.o

CURRENT_PATH:=$(shell pwd)
LINUX_KERNEL:=$(shell uname -r)
KVERSION:=5.4
KDIR=/home/allwinner/tina-d1-h/out/d1-h-nezha/compile_dir/target/linux-d1-h-nezha/linux-5.4.61
#complie object
CC=riscv64-unknown-linux-gnu-gcc
all:
        make -C $(KDIR) M=$(PWD) modules  CROSS_COMPILE=riscv64-unknown-linux-gnu-   ARCH=riscv

#clean
clean:
        make -C $(KDIR) M=$(CURRENT_PATH) clean

确认了一下，是800*480的，相关参数配置也是按照手册里进行的配置，附附件是厂家提供的手册，再麻烦帮忙看一下，多谢

大佬，RGB显示屏配置完后，时钟是正常的，其余的DE/VSYNC/HSYNC都没有信号
已经检查了屏幕是参数配置，没发现什么问题
请问有没有什么怀疑点，或者调试方向？求指点

suncw

@lovexulu
原理图输出18bit RGB (RGB666)
时钟是稍微差了一点，但是也在范围内，我往上调了一点现象还是一样，也是自测模式
lvds是也注释了，也没有效果。。。。

测了一下信号，时钟是正常的，其余的DE/VSYNC/HSYNC都没有信号。。。。

suncw

@yteraa
哦哦哦，这样呀，那我们再查一查配置的参数看看哪里有问题吧

suncw

@yteraa
大佬，现在显示屏一直显示纯色，而且很有规律，请问会不会是进入了什么测试模式？咱们这款CPU有类似的功能吗？

@yteraa
我对照了一下手册，lcd_hbp和lcd_vbp有点问题，修改后显示屏没有明显变化，还是之前的效果。
请问我修改后对照的参数有问题吗？

lcd_hbp:hsync back porch(pixel) + hsync plus width(pixel);   =Thbp+Thw = 8+4 = 12
lcd_ht: hsync total cycle(pixel)                                                = Th = 816
lcd_hspw:hsync plus width(pixel)                                            = Thw = 4
lcd_vbp:vsync back porch(line) + vysnc plus width(line)        = Tvbp +Tvw = 8+4 = 12
lcd_vt:vysnc total cycle(line)                                                   = Tv = 496
lcd_vspw: vysnc plus width(pixel)                                           = Tvw = 4

@yteraa
这是开机默认的效果

这是随便修改一个colorbar后的效果（echo 2 > /sys/class/disp/disp/attr/colorbar）

@yteraa
大佬，求助一下，用了default_lcd驱动后屏幕有显示了，但是显示不正常
我查了一下显示屏的参数，都是按照手册中配置的，没发现有错误，但是还是显示不正常
请问有没有什么调试方法或者建议

suncw

@whycan
HS VS没有信号
应该是使用错了驱动，安装楼上的lcd_driver_name修改后不是黑屏了

suncw

@yteraa
使用的ST7262，不需要初始化的屏
使用这些设备树配置后屏幕有显示了，但是屏幕一直都是白、红、绿、蓝、黑纯色在不停的换，期间还伴随这闪屏，怀疑是测试模式，因此去修改了echo X > /sys/class/disp/disp/attr/colorbar，发现只有闪屏的频率发生了变化，其余的没有变化
请问知道这是什么原因吗？

使用tina-d1-h linux系统，想调试RGB显示屏，配置完成后，显示屏黑屏（背光是外接的所以是有背光的）
把调试信息打开，发现有报错（disp 1 not support lcd output），不知道是不是这个原因导致黑屏的。求助一下帮忙看看这是什么问题，谢谢

首先我想实现一下系统运行的状态下更换显示屏（热插拔），因为更换了屏幕，所以显示屏的相关参数都需要修改。但是fb_fix_screeninfo默认不支持修改。

我想到的方法是将整个模块退出，修改参数，重新初始化显示模块。但是发现退出模块有问题，会打印堆栈。（直接调用disp_module_exit函数进行退出）

请问我这个思路可行吗？或者大家有什么其他方法吗？（使用的硬件是哪吒开发板，全志D1的cpu。软件是linux 5.4）

cfg_close_flow 初始化中有注册，应该不是空指针。另外将调用处删除后打印一样的堆栈信息，并且调用处有判断空指针，应该和那个空函数指针没关系）
