我所有的内核编译后更新 都是按照下面的步骤来的

CM5、cp4都是这样操作的

内核编译后 都是整个out文件夹打包的

@george

mkfs -t ext4 /dev/mmcblk0

日期也不对啊

@jugg 现在可以支持在coolpi机器上直接编译uboot。

@jugg 你试下不改多指配置，编译内核再更新有无报错，能自行改内核是最好的

@jugg 进入MSC模式直接用WINDOWS工具格式化就好了。

@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.

@george Thanks for your reply. Local videos from EMMC play well. I am talking about network videos in browser like youtube. Present driver and software ubuntu 24.04 (older kernel) uses almost 50% of CPU just to play a 1080p video. I have an Orange Pi 5b, that has same processor and GPU running orange pi droid (a version of android). That plays youtube videos with much less resources and runs much faster. I am looking for an android version to run on coolpi notebook. Where can I find that? (i have already tried armabian. but did not like that on coolpi laptop. Android for COM5 does not work)

@george
我已经发现了会独占屏幕 锁屏了图像还在。。

@大法师 谢谢！搞定了
ubuntu 20没有/etc/rc.local，需要

新建service
sudo vim /etc/systemd/system/rc-local.service [Unit] Description=/etc/rc.local Compatibility ConditionPathExists=/etc/rc.local [Service] Type=forking ExecStart=/etc/rc.local start TimeoutSec=0 StandardOutput=tty RemainAfterExit=yes SysVStartPriority=99 [Install] WantedBy=multi-user.target

2.使能service
sudo systemctl enable rc-local.service
3.新建/etc/rc.local
sudo vim /etc/rc.local
并需要操作的命令加进去
4.启动服务
sudo systemctl start rc-local.service
sudo systemctl status rc-local.service

@jugg
刷机占用多少，安装包预装以及使用过程apt 相关安装都会占用空间，还有系统/var/log/journal也会持续增长。具体可以逐个分析每个目录大小

cd / du -sh * --exclude="proc"

@george
可以编译了

@零度灬救赎
cat /proc/cmdline查看对应的console有没有指向ttyS0，如果有，可以编辑/boot/firmware/extlinux/extlinux.conf，更改指向tty0

@大法师
现在就是在CM5的安装盘里面改的
U盘我用来装WIn10都没问题

@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？

After letting the Laptop rest for a few days, the cam was back shortly, went away after a few seconds though.

@bbsvs2000
禁用rkisp、cif、csi
rk3588s-cp4.dtb

用于加载/boot/firmware/wifi.txt
wifi_precfg

sudo cp rk3588s-cp4.dtb /boot/firmware/rk3588s-cp4.dtb sudo cp wifi_precfg /usr/sbin/ sudo chmod a+x /usr/sbin/wifi_precfg sudo reboot

@大法师 收到，谢谢

@AugustRobot_Zou 👍 👍

@大法师
加了确实可以录
只是CPU使用率太高了 200% 300%了
