RE: 如果同时给emmc和sd卡刷系统，如何指定系统从emmc或sd卡启动posted in Pi 4B
@xingzhan2012 默认优先从tf卡启动，因为刷的是同一个镜像文件，需要你手动操作区分挂载的分区名称即可实现。

RE: Customize any Linux distroposted in Ubuntu
@sushruth You can mount the second partition based on the image file we provided, back up the /lib/firmware, /lib/modules directories, and then empty the contents of that partition. Then extract the Fedora Server arm64 base file system to the second partition mount directory and restore the backup contents. Finally, write to the storage disk again, such as tf card, insert coolpi4b to start system verification.
Please refer to the github link above the forum to read the ubuntu repository shell script.

RE: Trying to install pip3posted in Ubuntu
@MSUMMERS999 You can try boot system from emmc, and then insert tf card. Check it partitions table or format tf card. Please refer to the follow info.

RE: 能够通过修改配置文件切换TF和EMMC启动吗posted in Ubuntu
@allen 可以在任意一个系统中在线配置，修改extlinux.conf参数，将label指向对应的rootfs分区即可。默认刷机镜像rootfs分区均为writable，可以自行设定不同标识。

@MSUMMERS999 The current system doesn't need to do this. That's for earlier versions.

RE: 请问coolpi怎么使用csi摄像头posted in Maker
可以先用buildroot版本镜像验证CSI摄像头，Ubuntu与其他发行版本还在优化适配中。
对应镜像下载地址在百度网盘，请参考贴

RE: 今天已经2月中旬了，所以 CM5 啥时候出来？posted in Pi CM5
@顾真牛 said in 今天已经2月中旬了，所以 CM5 啥时候出来？:
@大法师 我又仔细看了下资料
- 按键的位置有点尴尬，是接口吗？
- 好像摄像头和显示器的MIPI接口都取消了 ，至少摄像头的留一个吧！
- 发现有个蜂鸣器，现在一般还有这个需求么。。。
- 好像没散热风扇的电源接口 核心板在背面，要接线过去挺麻烦的。
CM5 是核心板命名。你看到那款是整机带外壳的 minipc
