@hangman 不是修改cmdline.txt，应该更新extlinux/extlinux.conf

@jugg said in Cool pi 4B & CM5 探索快速安装系统新方法:

到底怎么样才能还原系统


没法自己进入还原系统啊
用的金士顿的U盘

更新2023年发布的loader程序，更换u盘再验证

@jugg said in Cool pi 4B & CM5 探索快速安装系统新方法:

是不是有什么特别的地方
放两天板子的系统就进不去 又是怎么回事
串口有问题 又是怎么回事

确认串口连接线是否松了或接对

@jugg 串口线型号是什么，是在windows 系统使用？相应的驱动确认一下

@jugg 没有什么特殊的。

@jugg 看信息，系统分区有损坏，修复看看

@阿里 有串口日志信息，发个看下。上传的图片看不到

@etrin take one udsik, and then make a bootable udisk with Rufus.exe. Insert it to cm5-evb, reset or power on, you will look the installing progress through hdmi display.

@LinuxRk3588 said in CM5 EVB 调试情况咨询:

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)？
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？
3、pcie 3.0 x4目前兼容哪些外设方便总结下不
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？

4. android sdk 4b与cm5 evb是共用的，网盘可以下载，也有相应测试镜像

@carloshenrique

https://github.com/yanyitech/batocera-coolpi-linux/releases/tag/V1.0

@jugg 手动或自动，你可以评估选择。分区必须要有才能挂载

@jugg 需要。

@aero coolpi/123 试下

@NeverEnd
用这个版本重新做个启动U盘，插入TF卡，插入U盘，开机安装

@Macs @carloshenrique I'll verify that version 38 wireless network and audio capabilities.

@jugg
找下是哪个ko驱动，加到黑名单中

cat /etc/modprobe.d/blacklist.conf

其他方法，网上找的参考
https://blog.csdn.net/weixin_45627376/article/details/128102913

@jugg 修改4b内核配置，根据你自己的需要配置。

CONFIG_VIRTIO_NET=m

@jugg 短接maskrom不需要额外按压powerkey按键

@jack_admin said in how about batocera with cool pi 4b:

Test firmware link

百度网盘 batocera36

Onedrive coolpi4b batocera36

@Macs have you test version 36?

@jugg 保持短接，断电再重新上电（usb线先拔掉）

@hyx

1. 单独拿一个U盘，使用refuse工具，将udisk install专用目录下的镜像刷入U盘。

2. 将做好的U盘插入4B主板USB3端口（下面一个），插上TF卡，上电开机。

3. 如果有接HDMI显示器，可以查看安装过程（全自动安装），安装结束提示拔出U盘。

4. 按power按键开机，启动进入安卓系统。

@jugg

查看当前cpu运行频率

sudo cat /sys/bus/cpu/devices/cpu*/cpufreq/cpuinfo_cur_freq

命令设置性能模式

echo performance | sudo tee /sys/bus/cpu/devices/cpu*/cpufreq/scaling_governor

@qys2022 你用了几路网口

@jugg 现在可以支持在coolpi机器上直接编译uboot。
https://www.cool-pi.com/topic/380/cool-pi-4b-cm5-linux-system-support-compile-u-boot/3

本机也可以直接编译u-boot源代码。

补充安装依赖，再更新编译脚本

sudo apt install device-tree-compiler python2

@97842484 你的xdma驱动问题解决了没？系统支持U盘自动备份与自动安装

@97842484 可以支持U盘全自动安装

@97842484 哪天ubuntu官方加入板卡支持，就能直接安装了。
