20251223给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-6.1】系统时使用weston-screenshooter截屏【修改直接编译进IMG固件】
2025/12/23 19:23

缘起：给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-6.1】后，需要使用weston-screenshooter截屏。
不想每次刷机之后再去修改S49weston文件。

/usr/bin/weston 2>&1 | tee /var/log/weston.log &
修改为：
/usr/bin/weston 2>&1 | tee /var/log/weston.log &

4线USB2.0通过adb直接拿到电脑上的速度是：31.3 MB/s
写入TF卡的速度略微低于31.3 MB/s【大概为25.56MB/s】

需要实测开发板丝印ETH1芯片RTL8211F-CG的网速。
通过ifconfig确认为eth0。

需要使用ov5645的驱动框架来适配LVDS接口的105机芯。
按照以前的经验，首先关闭I2C的读写！
结果，肯定会出现某些地方遗漏的，只能通过编译器来检查问题了！

当你把荣品RD-RK3588开发板重新适配一把，就相当于从头做了一个项目：【荣品RD-RK3588开发板】。
当然，开发板的功能都是好的，你免除了调试的过程，也就没有解决相关硬件出错的经验/机会了！

1、出错了！

weston桌面系统截屏方法
二月 3, 2023

使用weston-screenshooter

但必须启用weston桌面--debug选项，否则会出现以下错误：

[root@RK356X:/]# weston-screenshooter
[02:41:05.145] libwayland: error in client communication (pid 776)
weston_screenshooter@5: error 0: screenshooter failed: permission denied. Debug protocol must be enabled
以RK3568开发板，buildroot系统为例，修改/etc/init.d/S50launcher，找到weston所在行，添加--debug选项。

......
# Uncomment to disable mirror mode
# unset WESTON_DRM_MIRROR

export XDG_RUNTIME_DIR=${XDG_RUNTIME_DIR:-/var/run}
export QT_QPA_PLATFORM=${QT_QPA_PLATFORM:-wayland}

weston --tty=2 --debug --idle-time=0&
{
# Wait for weston ready
while [ ! -e ${XDG_RUNTIME_DIR}/wayland-0 ]; do
sleep .1
done
/usr/bin/QLauncher &
}&
......
forlinx开发板使用的yocto系统也类似，修改/lib/systemd/system/weston.service，在weston后添加--debug选项。

$ vi /lib/systemd/system/weston.service
# 修改如下
# ExecStart=/usr/bin/weston --debug --log=${XDG_RUNTIME_DIR}/weston.log $OPTARGS
然后重启系统，之后就可以使用weston-screenshooter截取屏幕了。
