RE: 请问coolpi 4b 电源输入功率多大合适,有电流保护吗?
@night 机器TYPEC前端电源芯片耐压可以达到28V,极限可以到34V,所以你的适配器规格没有任何问题。
开发板的电源部分一直是我们设计最优先考虑的方向,所以前端第一级电源花了很多功夫,考虑到用户各种各样适配器的规格,最终选择目前国内少数几家真正能做车规级别电源方案的厂家。尽量保证前端电源稳定可靠。

Coolpi 4b with Ubuntu22 running panfrost gpu driver performance testing
CPU
测试方法:
sudo apt install sysbench
RK3588S单核心每秒事件数2598,8核每秒事件数13846;同步对比 i7-7700 ,单核每秒事件数1438,8核每秒事件数8469。可见ARM在CPU方面并不比X86弱。GPU
测试方法:
sudo apt-get install glmark2* -y
X11 gl
X11 gles 3.1
WAYLAND gl

RE: Heatsync options
@zensation The radiator can be matched with raspberry pi. A separate fan is OK. Normally, it is not necessary to add aluminum alloy fins on the CPU.

RE: merge back to armbian source
@igorp
Recently, I have been working hard to push CM5 NOTEBOOK to the ARMBIAN mainline. Further information will be released as soon as possible. Thank you for your support.

Coolpi uses UMS to update the system
Coolpi supports UMS to update emmc firmware, as follows:
- Update the latest versions of loader and uboot images. You can also synchronize uboot code and compile it yourself.
git clone https://github.com/yanyitech/coolpi-loader cd coolpi-loader ./build-uboot.sh cp4b
- Connect a dual A port USB cable to the computer and the upper USB 3.0 interface. Plug in the power and press the power button three times, and the machine will enter UMS mode.
- Use Etcher software to update the software.

RE: [ ubutnu 22.04 ] AP+STA mode 似乎無法同時啟用?
内核已经更新,同步develop代码到最新,编译替换内核,KO文件解压到/lib/modules目录,重启机器会看到两个WIFI节点。
使用其中一个连接外网
另外一个可以作为热点
