@zuoooc 该版本镜像暂不对外。如项目性质可私聊

大神可以发一下教程吗

@george fc2f87b3-499a-4776-870a-a2561f6f19d9-image.png

原因找到了，是configuration 那里要设置选择HFP

启动是成功的，只是ttl终端没能操作，hdmi上有桌面，能正常操作。

@大法师 先支持HQ Camera吧，视觉应用是大头

@edwardzhou 提示在显示器输出进度，当然也可以修改console切换到串口输出

@allen 内核打开binder IPC

@macthree 建议全新安装会更好，0303版本是纯净版系统，您也可以下载我们github ubuntu仓库构建纯净版本镜像

@edwardzhou 用U盘备份安装系统，不用考虑移除emmc

@顾真牛 rknn为啥是垃圾啊？

@jack_admin

可以使用，感谢。
的确关掉效果没有绑定大核好。

@tonyone0902 如果有环境，建议更新到0315 版本loader。

@大法师 建议尽快支持一下树莓派的HQ Camera，传感器型号是IMX477R，现在这款摄像头很火，可以匹配各种不同的镜头。IMX708支持自动对焦，是新出的产品。

参考帖子
https://www.cool-pi.com/topic/131/coolpi-4b-linux-kernel开发在线更新说明/4

@lej40 said in Type c power port:

Is the the type-c PD port also a USB-c data port

Sorry,This port is used for power supply and has no data connection.

@tonyone0902 如下图所示，板子的BOTTOM面有测试点，可以焊接外部电源。

机器本身不具备电量侦测功能，可以外加库仑计通过I2C接口。

补充内核编译操作说明（如下以coolpi 4b ubuntu22.04 0306系统版本为例）：

首先下载内核源码

coolpi@coolpi:~$ git clone https://github.com/yanyitech/coolpi-kernel.git Cloning into 'coolpi-kernel'... remote: Enumerating objects: 8550563, done. remote: Counting objects: 100% (5962/5962), done. remote: Compressing objects: 100% (3084/3084), done. remote: Total 8550563 (delta 2757), reused 5819 (delta 2648), pack-reused 8544601 Receiving objects: 100% (8550563/8550563), 1.98 GiB | 11.07 MiB/s, done. Resolving deltas: 100% (7166058/7166058), done. Checking objects: 100% (33554432/33554432), done. Updating files: 100% (87196/87196), done. coolpi@coolpi:~$

额外安装组件包

coolpi@coolpi:~$ sudo apt install -y flex bison libssl-dev coolpi@coolpi:~$ sudo ln -sf /usr/bin/python3 /usr/bin/python

开始编译内核

coolpi@coolpi:~$ cd coolpi-kernel coolpi@coolpi:~/coolpi-kernel$ ./build-kernel.sh cp4b

@ccjjww1222 V11版本是板载天线。V10是外置天线，你的是哪个版本

@george 不错不错 银子准备好了 就看你们啥时候出了

@jack_admin I mean can output video signal on the gpio using with custom timings, like you can on the RPI4?

@大法师 是权限问题，修改/media/coolpi文件夹的用户为coolpi就可以了

@test 你的loader版本看起来比较早，升级loader试下。卡的分区表异常，格式化一次

@george 试了不能用

@jack_admin 已经成功

可以通过了，就因为文件路径存在空格

@jack_admin 👍
