How to add swap file with cool pi 4bposted in Maker
Swap is a space on a disk that is used when the amount of physical RAM memory is full. When a Linux system runs out of RAM, inactive pages are moved from the RAM to the swap space.
Swap space can take the form of either a dedicated swap partition or a swap file. In most cases, when running Linux on a virtual machine, a swap partition is not present, so the only option is to create a swap file.
Example Add 8GB swap memory
sudo dd if=/dev/zero of=/swapfile bs=1M count=8096 sudo chmod 0600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstabsudo mount -a or reboot

RE: Coolpi 4b 镜像固件离线刷机方法posted in Pi 4B
@lyd 摄像头接口注意不要随意接DSI，电源信号如果不对会烧坏的。
正常情况下接入CSI摄像头，查看系统信息，判断是否识别，再打开摄像头应用软件选择相应摄像头。
比如打开终端输入命令：
dmesg | grep ov5ls /dev/video* -lhttps://www.cool-pi.com/topic/180/coolpi-4b-support-ov5647-camera-module/16

@likeshixi
支持的，需要配置内核驱动，另外补充相应的firmware文件iwlwifi-ty-59.601f3a66.0.tgz 解压到/lib/firmware
github拉取内核同步编译试下，已加入该模块配置
