RE: ubuntu 22.04 chromium-browser 打開後,會直接重新啟動
@tonyone0902 This is usually caused by unstable power supply, such as insufficient input power of the adapter, or power failure at the moment of switching.

RE: Coolpi 4B armbian support
@HiramXMaxim Please provide the model of the card reader you use, or take a photo and send it to us. Let's buy the same model and test it. thank you.

RE: Coolpi 4B armbian support
@HiramXMaxim This may be the compatibility problem of the card reader. You can first make the image into the TF card, and then use the migration script of armbian to migrate the image to EMMC.

@retroman Try formatting the TF card before mirroring it. If it does not work properly, it is recommended to upgrade the loader file.

@HiramXMaxim The EMMC small board has an adapter for converting to TF card, which can be written to the EMMC using a common card reader. As shown in the figure below.

@花月 注意python版本,其它都是一样的。ubuntu22.04 默认python3.10,要注意切换一下。

RE: 能不能整理个完整版的说明文档呀
@花月 具体一些,需要哪部分?因为本身linux系统相当庞大,基础的操作文档网络上的资料可能更系统一些。如果针对某些特定模块可以提出来。

RE: 买的lcd屏幕 hdmi的在orangepi里有显示。但是在你们这个板子上黑屏
@tscmga 在你自己做的这个板子上面把HPD信号的驱动能力增强试试。极限情况下可以直接接5V.
下面这款我们有测试过:

RE: 买的lcd屏幕 hdmi的在orangepi里有显示。但是在你们这个板子上黑屏
@tscmga 这种非标设备暂时没有很好的办法兼容,会导致故此失比,我们之前有测试一款7寸的HDMI+USB触摸的是可以正常使用的,晚一点发链接给你。

RE: 请问coolpi 4b 电源输入功率多大合适,有电流保护吗?
@night 机器TYPEC前端电源芯片耐压可以达到28V,极限可以到34V,所以你的适配器规格没有任何问题。
开发板的电源部分一直是我们设计最优先考虑的方向,所以前端第一级电源花了很多功夫,考虑到用户各种各样适配器的规格,最终选择目前国内少数几家真正能做车规级别电源方案的厂家。尽量保证前端电源稳定可靠。

@zensation If this is the case, it means that the image you are using is incorrect, or it is not successfully created.

RE: Heatsync options
@zensation The radiator can be matched with raspberry pi. A separate fan is OK. Normally, it is not necessary to add aluminum alloy fins on the CPU.

RE: Coolpi 4b Ubuntu22.04 原生系统
@zensation You can use the shell to log in, expand the partition capacity, and then try to log in from the UI interface.
