RE: I want to install pytorch and torchvision.
@etrin
This is related to the system's Python. If using ubuntu22.04, the Python version is 3.10. You can also try lowering the system's Python version, but it may cause other issues. -
RE: CM5 EVB 调试情况咨询
@anernest
Please provide the specifications of the monitor and the PIN definition of the interface, and we will evaluate whether it can be supported? -
RE: Laptop install Ubuntu on nvme
@Momo-0
There is no abnormal log information found in the dmesg information. Do you have any USB to serial port tools in your hand, and do you have some hands-on skills, such as welding and debugging serial ports. If further debugging information needs to be obtained, it is necessary to capture the logs of the serial port sleep wake up section to confirm the direction of the problem. -
RE: CM5 Laptop Promotion
@anernest
This product is designed for enthusiasts and is very suitable for DIY users to develop, assemble, and build their own. Currently, after dismantling the machine, they do not enjoy after-sales policies. However, various accessories of the machine, including motherboards, core board and shell materials, can be sold separately for secondary sales. And we have a dedicated team to assist users in solving various problems in use and design. Notebook products are an extension of the CM5 core board, and currently there is no separate theme in the community. If you have any questions, you can directly post them under the CM5 theme. Thank you for your support.- The latest laptop motherboard design has changed the WiFi section to a standard M2 interface, making it easy for users to replace according to different needs. Early machines can also be upgraded by replacing the motherboard.

RE: Laptop install Ubuntu on nvme
@Momo-0
After booting up, print a dmesg message and send it out. I think this should be a single machine issue. Normally, our machine does not have this problem. -
RE: Laptop install Ubuntu on nvme
@Momo-0
Configure according to the factory's configuration (both the file system and kernel are placed in EMMC, while nvme only serves as a data disk). Is there a problem with suspend? -
RE: CoolPi 4B USB Alt Mode
@Mz3D-0
Sorry, The typec port of cp4 machine only support power input and cannot support power output and dp output.
You can pay attention to CM5's laptop products,which come with a standard TYPEC interface and support ALT mode to output power and display port output simultaneously.

RE: I failed to install Ubuntu 22.04 on Cool pi cm5
@etrin
Do you have a USB to serial port tool? If you can provide a startup log, it will be more convenient for us to analyze and solve the problem. Based on the current description, the possibility of insufficient power supply is relatively high. It is recommended to replace the TYPEC adapter before testing. -
RE: Please tell me how to use Segment Anything Model on Coolpi cm5.
@etrin
Please refer to the following document to configure the NPU environment for CM5 and test it.https://www.cool-pi.com/topic/288/quickly-build-an-rknn-environment?_=1699186747376

RE: After copying the image to emmc on Cool Pi cm5, I turned it off and turned it back on, but it still doesn't boot.
@etrin
Is the phenomenon of constantly restarting after upgrading the image? Have you seen the startup logo image? If the power adapter is constantly restarted, it is highly likely to be a problem. It is recommended to replace it with an adapter that supports the PD/QC protocol for testing. -
RE: Cool Pi ARM Notebook Preview
@ngavarta
In the early stage, there was a plan to use a copper tube heat sink as shown in the figure below for heat dissipation between the CM5 and the fan. Later, the machines shipped were changed to passive graphite copper sheet heat dissipation.

RE: CM5 EVB Typec 接口问题
@LinuxRk3588
1.CM5-EVB的typec接口只有供电功能,没有USB和DP功能。
2.调试接口可以使用TTL或者网口,这个底板的原理图和PCB文件在wiki可以下载。图纸上有完整的信号定义。
3.SATA电源是标准的12V 5V设计,丝印上也有标注。
4.上层的USB3.0接口是OTG接口,可以软件配置HOST或者DEVICE功能,其它USB接口都是HOST。 -
RE: Laptop install Ubuntu on nvme
@Momo-0
After the laptop enters suspend mode, the power indicator light will turn off. When the power button is pressed again, the power indicator light of the machine will first light up, and then the machine will wake up. -
RE: Laptop install Ubuntu on nvme
@Momo-0
Currently, there is no open cover wake-up, and you need to manually press the power button. This is a known issue that can be resolved by updating the kernel in the future.As a development laptop, this machine will mainly focus on user-defined images. We have scripts for customized images available on Github, and we welcome everyone to download and use them.

Closing the laptop cover will put the machine into sleep mode. -
RE: Laptop install Ubuntu on nvme
@Momo-0
The current images are written to EMMC by default. If you want to boot from nvme, you can perform partition copying on the system. Then modify the partition label on NVME, and then modify the label of the corresponding cmdline boot partition. You can achieve NVME charging and startup. -
RE: CM5 EVB 调试情况咨询
@LinuxRk3588
CM5的DSI接口暂时没有做和树莓派PIN TO PIN的排线,规格差距太大,CM5的DSI可以支持2路MIPI 4LINE同时输出,而且兼容2路触摸。用户可以根据自己MIPI屏的规格做转接。 -
RE: CM5 EVB 调试情况咨询
@LinuxRk3588
1、pcie 3.0 x4 现在实际测试速率可以达到多少?论坛上有人说只能支持到pcie 3.0 x2? 只能到X2,理论速度单line是8GT/s,X2就是16GT/s。
2、mipi dsi的转接线淘宝有卖吗?csi的转接线我看到是有,那个支持双mipi csi接口的转接排线是可以直接接树莓派的两个IMX219模组是吧?转接排线淘宝网店就可以买到,可以同时支持两个IMX219工作。
3、@jack_admin 后边有针对类似CP4目前支持的国产操作系统(麒麟之类的)也支持到5evb上吗? 麒麟和统信目前只有CM5-NOTEBOOK可以支持。因为还存在一些兼容性的问题,暂时没有推到CM5-EVB和CP4。 -
RE: CM5 EVB 调试情况咨询
@LinuxRk3588
1、CM5 EVB mipi dsi/eDP 支持哪些屏幕可以列个清单吗?兼容树莓派的接口(看原理图好像不一样)?
这个接口和树莓派是不一样的,我们有做转接排线,可以兼容树莓派的sensor。
2、想确认下现在CSI接口 IMX219(树莓派接口相机)在该板子上的适配情况?
IMX219目前是可以支持的
3、pcie 3.0 x4目前兼容哪些外设方便总结下不
可以支持通用的PCIE设备,比如网卡 SATA扩展板 WIFI等,一般X86的ubuntu版本可以支持的外设都可以支持。
4、发现cm5 evb 目前还没有android相关的SDK 开发包是开发组有碰到什么问题吗?有没有release的一个计划表?
android版本可以参考CP4的源码自己更换DTS即可,这个建议用户自己实现。 -
