@enok71 What's the budget price?

@zehui 多交流，共进步

@zehui 重新勾选再刷一次

@银河铁道 你可以试试把u20版本内核拷贝到u22系统上，对比验证下

@hyx 可以看看日志排查启动慢的原因，主要开销花在哪个部分。

@kaktus The current loader does not support decrypting boot partition.

@银河铁道 可以考虑适配一个。

@hyx 你这是server版本？可以网络搜索参考配置，都是通用的

@hyx 是什么版本？启动过程查看串口信息结合分析

@阿里 你刷的哪个镜像？有没有根据你设计的底板修改源码

@大法师 said in Coolpi 4b 镜像固件在线刷机方法:

UMS模式

什么是ums模式嘛？
我用RKDevTool 会出现加载固件失败.
我在网上抓的是
20230613-ubuntu-20.04.5-preinstalled-desktop-arm64-cp4b.img

可是我看你上面教程的档名有emmc在里面.
给RKDevTool用的img档在哪嘛?

为减少操作复杂度，我们提供的镜像系统默认不使用RKdevtool烧录。

仅限于loader引导程序用RKdevtool更新烧录。

@qys2022 如果没有使用，可以禁用

@YDY123 4b和cm5的gpio引脚定义不一样。

@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.

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
