@yfblock intel ax201
但前提是你需要编译内核，启用intel的驱动模块，并且把官方intel的固件拷贝进去就行了。

coolpi默认屏蔽了intel

@Momo-0
The 3.5mm headphone jack has output and MIC functions.

@george Never mind. It just started working. No clue why, but I'll monitor it and let you know if it starts to get flaky.

@mez62 可以插上试试

@george Is there a possibility for /boot/ on the FLASH and then the root partition being on the nvme drive with the uboot?

@george
Many thanks for your reply. Is there any guide about how to compile mpp/rknpu module with cool pi kernel?

And is it possible to compile cool pi kernel 6.1 with panfork?

@28717885
发规格书看看，具体是什么东西？

貌似是arch带的编译器版本太高了
用老编译器编的内核可以正常使用panthor

@mainbord
At present, the mainline kernel EDP interface is not supported. The CM5-LAPTOP configuration has been submitted for mainline review and should be released soon.

just use flatpak

there are many app on flathub with arch64 support.

@plumlis The performance is perfect, there is absolutely no issues present, on glmark2 with Xorg all tests are running between 1400-1500 fps(this is heavily window system dependent so take it with a HEAVY grain of salt when making comparisons!!!). I have much better battery life as well. Everything is much better than my previous laptop.

My harddrive I used to compile armbian with 6.1 broke, all though If you are willing I could send patches, the issue with my specific setup is that it highly depends on out of tree patches. Perhaps I might be able to upstream some of it to the coolpi armbian github? Although the issue with that is that I am locked out of my google accounts currently.

If you are willing to put in (not too much) effort I could send you some patches to apply to the official Coolpi Armbian repository, note that it requires a x86_64 Intel/AMD machine with Linux and Docker(If you dont use Ubuntu).

@plumlis
This method has been tried before, and as you said, the actual effect can be seen in the Ubuntu system. However, if it is a system with kylin and uos, it must always run in performance mode to run smoothly. We will re evaluate whether to update to the existing kernel configuration. Thank you for your suggestion.

@plumlis
The testing before AX210 was problematic. The most basic BT cannot recognize it, it seems that the firmware version of WIFI is incorrect.

@plumlis
FFmpeg can be changed to a native package. Or using the Chromium browser, the decoding issue of this player has been bothering us for a long time. Take some time later to focus on solving it.

@plumlis
The battery of the RTC connector has a spacing of 0.8mm. From the current phenomenon, it is not that the hardware RTC cannot save time, but rather that the hardware RTC time has not been synchronized with the system. So adding this battery won't make any changes.

@george
Nice, I'll waitting for good news.

@yaitoro
Yes, this is the official store address.

@plumlis
对，就是这个地方，自行修改就好了。

How to update to 6.x kernel?
I tried to compile this
https://github.com/yanyitech/coolpi-kernel/tree/linux-6.1-stan-rkr1
Next I install kernel according to the instructions
https://forum.cool-pi.com/topic/514/cool-pi-cm5-laptop-linux-quick-start-guide

5.10 installed successfully but after install 6.1 it's does not booted

@george

mkfs -t ext4 /dev/mmcblk0

then it success

@Rock
You can download the image again to the 24.04 system directory. If you downloaded to 22.04 before, you must first mount mmcblk0p2 to the system and then find the image you downloaded earlier in the corresponding folder.

@Momo-0
At present, PD charging only supports charging when turned on, and does not currently support charging when turned off. The protocol only supports TYPEC PD format and does not support QC standards. So you need to use an adapter with TYPEC interfaces on both ends as shown in the following figure:

@Ranomez
This machine is the latest version of V20, and I have understood the issue you have reported:

This noise is the bottom noise of the audio codec that is amplified by the power amplifier and output. In fact, the native bottom noise is very small, which can be confirmed by inserting headphones. It's only after being amplified by the amplifier that you can hear it near the ear at the speaker end. To avoid this common problem, the traditional approach is to only turn on the amplifier circuit when there is audio output, and then turn off the amplifier after the audio is played. This way, the normal sound output will cover the background noise, as shown in the driver code below: static int es8316_mute(struct snd_soc_dai *dai, int mute, int direction) { struct snd_soc_component *component = dai->component; struct es8316_priv *es8316 = snd_soc_component_get_drvdata(component); es8316->muted = mute; if (mute) { es8316_enable_spk(es8316, false); msleep(100); snd_soc_component_write(component, ES8316_DAC_SET1_REG30, 0x20); } else { snd_soc_component_write(component, ES8316_DAC_SET1_REG30, 0x00); msleep(130); if (!es8316->hp_inserted) es8316_enable_spk(es8316, true); } return 0; } Your current operating method is to only turn on the amplifier without normal audio data output, which is equivalent to the amplifier only amplifying background noise data. So what the speaker hears is the amplified background noise. The current situation I have tested here is that the ear needs to be close to the speaker to hear, which cannot be heard in normal usage scenarios. Later, we will try to adjust the gain configuration of the amplifier at the driver end, hoping to reduce the amplitude of this noise, but it is unrealistic to completely eliminate it.

@george

Thanks for your reply and insight. As for the thickness of the shell, i actually think that is a positive point, the thick shell makes it very well suited for people like me (ict-manager) I feels like it will travel well: The sturdiness, passive cooling, power efficiency and having a large battery is just what i need.
As for the RTL driver slowing boot time, thanks for the info. If i used the AX200 instead i probably wouldn't have known about it.

If i where to put my finger in something, (im being really nit-picky now) The charger has an awkward shape (43mm wide). Asus has a nice 12v 3A charger (36mm wide) with the correct 4.0x1.7 plug. Just ordered an off-brand variant for 25$ (inc. shipping and vat)

Having used it for about a week now, there is very little that i would change about the laptop itself, (Optional back-lit keyboard maybe?)
When kernel support hits mainline, I think the CM5 laptop will become interesting to a wider group of people.

@max
I'm very sorry for any inconvenience caused. Thank you for the support of your Coolpi product. I have applied to the company for a new V20 motherboard for you free of charge. Please email your receiving address. george@cool-pi.com
