systemctl poweroff

@happyday
拍个照片看一下，也可以直接断电重启，第一次启动会格式化扩展磁盘分区，会慢一些。

@Android2002
modules.tar.gz 可以不用拷贝，放其它目录一样的。

@Android2002
可以先删除boot/firmware里边的文件，然后再拷贝。注意删除前最好备份一下，否则错误的文件会导致系统无法正常启动。

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

1. 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.
2. 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;
}

3. 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.
4. 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.

@Ranomez
If you can open the back cover of the machine, please take a photo and send it out, I will confirm the version.

@Ranomez
Can you confirm if your machine is V10 or V20 version? When did you probably purchase the machine?

@Android2002
这个需要使用etcher工具烧录，不是瑞芯微开发工具。

@Rock
1.First, download the image to the COOLPI laptop
2.Then insert the USB drive into the laptop, double-click on the image and the following interface will pop up. 3.Then select the USB drive, and the image will be created into the USB drive
4.Restart the laptop and the machine will boot from the USB drive. After entering the system, copy the 24.04 image into the USB drive.
5.Double click on the 24.04 image in the USB drive directory, select EMMC (starting with AT29), and enter the root password. The image will be flushed into EMMC.

@Rebel-Rider
Regarding the issue of startup speed, it is mainly due to the initialization time of the RTL8852BE driver, not the speed of the EMMC. We are still trying to find ways to optimize this.Think you.

@Rebel-Rider
Thank you very much for your support of Coolpi products. As a DIY laptop, the extreme thickness is not very user-friendly, and the main issue is that there may be a lack of sufficient internal space for secondary development.
Regarding the issue with the kernel version, as the original factory has not yet submitted an update to the hardware encoding and decoding part of the 6. x kernel video, the machine is currently using 5.10.110. We will synchronize the submission once this issue is resolved.
After the mainline kernel 6.8, devices that natively support CM5 have also been designed for laptops based on the CM5 core board, allowing for synchronous use of the mainline kernel. The mainline version of uboot has also been merged into the mainline recently.
Communicate promptly if there are any issues during use. Thank you again for your support.

@happyday
是的U盘相当于硬盘，机器会优先从U盘启动。不需要做其它操作。制作U盘镜像之前建议先格式化一下U盘。

@reallaowu
coolpi的笔记本电脑和X86的方式不同的，coolpi是通过uboot引导的，镜像也不能使用ubuntu官方发布的，请按照如下文档操作更新：
https://cool-pi.com/topic/514/cool-pi-cm5-laptop-linux-quick-start-guide

@czzzz
百度网盘有最新的NPU SDK发布包。下载替换对应的库即可。

@mxpfeng 这个核心板EMMC部分损坏。找售后处理。

@mxpfeng
uboot的地址是1000开始写，不是4000.

@mxpfeng
uboot你有没有刷过，可以先把uboot重新升级一次，然后再尝试切换EMMC。

@mxpfeng
如果切换还一直失败就可能是EMMC模组有问题了。你可以把镜像做到U盘里边，尝试使用U盘引导机器，然后进入系统以后使用linux命令格式化EMMC

sudo mkfs.ext4 /dev/mmcblk0

@mxpfeng
下载完loader以后可以先读取一下FlashID和Flash信息，看看目前默认是在哪个存储设备。

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

@max
I think this is likely caused by a partial malfunction in the power system. You can send an email to george@cool-pi.com I provided a schematic to assist you in analyzing it together, but I did not understand what the first malfunction was like? Can you please provide a detailed description. We deeply apologize for any inconvenience caused to you.

Run the following command and upload the result.

@Rock
The Ubuntu 24.04 image has really been released and can be obtained from Baidu Cloud or Onedrive. Thank you for your support.

@guyii
From the phenomenon you described, it appears that the onboard EMMC partition table has been damaged. Try formatting the onboard EMMC memory according to the following operation method. After successful completion, you can enter UMS mode normally.

1. Find a USB drive and use an etcher to create an image of Ubuntu on it. Remember to back up important data from the USB drive before creating it.
2. Insert the USB drive into the USB port of the laptop and start the machine. If everything goes smoothly, the machine will successfully boot from the USB drive.
3. Use commands to format onboard EMMC memory

sudo mkfs.ext4 /dev/mmcblk0

4. Remove the USB flash drive and press and hold the power button for 10 seconds to forcibly shut down the machine.
5. Connect the TypeC port to the X86 computer and press the power button multiple times to enter UMS mode.

@drw_08
We have plans to push the machine to the Armbian main line, but some business issues have not been resolved yet. We will notify you as soon as we enter the exhibition.
We will release the CM5 laptop version of Ubuntu 24.04 soon.
Thank you for your support.

E: Unable to locate package libnautilus-extension1a

The package shown in the figure cannot be found. A simpler method is to first block it.
