比如充电芯片选择，电量计型号，包括电池充放电曲线测试及后期的软件调试，我们可以提供支持。你要做的就是自己设计一块充放电管理的板子。

@jugg
直接买一个12V的电池模块就可以用了。
如果要想自己设计一个，可以系统获取电量的，我们可以提供设计方法。

@Xelef2000
You can send an email if you need schematics: george@cool-pi.com

@jugg
我们暂时没有这种模组推荐，充放电管理要做好，其实还是有一些难度的。这个如果你有兴趣，我们可以提供指导。

@ytfycy
感觉还是配置问题导致的，直接刷我们发布的镜像有没有问题？

@ytfycy
ifconfig结果发上来。

@ytfycy
从log信息看没有什么异常：

[   80.959110] fuxi_phy link phy speed changed,0->2
[   80.959199] fuxi_phy now is link up, mac_speed=1000.
[   80.959262] fxgmac_phy_update_link phy reg1=0x796d, 0x796d
[   80.959316] IPv6: ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready

ping 不通吗？ifconfig看一下。

@ytfycy
shell输入

dmesg >log.txt

然后拷贝发出来。

@ytfycy
上传一份完整的dmesg log。

@樱月樱诗 USB接的哪一个口？应该是接上层USB3.0接口。

The current human-computer interaction interface of uboot is not yet perfect. We are trying to do this and will notify you of the version launch as soon as possible. Thank you for your support.

@ytfycy这个logo信息是不对的。

Two WLAN nodes are normal, and the default configuration for drivers is to generate two nodes, even one node can be used.

I'm really sorry, this board was tested before it was shipped, and it could also be caused by an abnormality during transportation. I will arrange to send you a new one. Because it is currently the May Day holiday, it may need to be processed after the holiday. I deeply apologize for the trouble I have caused you.

@Momo-0
From the log information, it appears that the USB Bluetooth network card was not recognized. It is recommended to remove the core board, remove the WIFI module, clean the gold finger with an eraser, and then install and retest.

@Momo-0
Run the following command and send the result.

At present, the maximum version supported by coolpi laptop is 23.04. Ubuntu 24.04 has just been released a few days ago and adaptation will take some time. It is expected that a version will be released in May. Thank you for your support.

You can use the armbian script on GitHub to build. The address is as follows:

性能肯定会有损失，从目前群控那边的情况来看，没什么太大问题。

@masterli
只是不支持硬件虚拟化指令，不影响KVM安装使用。

Do you need to buy a separate CM5 core board?

@ytfycy
1.核心板可以支持PCIE3.0X4 ,目前对应的evb底板只有PCIE3.0X2.
2.笔记本的SSD接口是M2的PCIEX4接口。

• Rockchip ARMv8 Cortex-A76 testing on Ubuntu 22.04 via the Phoronix Test Suite.
  

• Results
  

• HPL Linpack
  HPL is a well known portable Linpack implementation for distributed memory systems. This test profile is testing HPL upstream directly, outside the scope of the HPC Challenge test profile also available through the Phoronix Test Suite (hpcc). The test profile attempts to generate an optimized HPL.dat input file based on the CPU/memory under test. The automated HPL.dat input generation is still being tuned and thus for now this test profile remains "experimental".

@jugg
我觉得应该是你系统的ko和内核不匹配导致的，使用如下命令解压ko到系统，然后重启试试：

sudo rm /lib/modules/* -R
sudo tar -zxvf /boot/firmware/modules.tar.gz -C /lib/

@jugg
ubuntu显示框架改为X11，22.04 wayland还是有些问题。

@jugg 再ubuntu通过apt source可以获取源码，放在debian下面编译安装，可能会有一些依赖包的问题，自己想办法解决一下。

@ytfycy
缺少什么包就安装一下。
