@jugg 用帖子上提供的loader链接

@jugg 开机logo更新

https://www.cool-pi.com/topic/211/coolpi-4b-support-dynamic-update-logo

@xingzhan2012 已买了模组，计划调试

@jugg 这是ubuntu或发行版本通用的操作方法，再搜索找找，找到了分享一下

@jugg said in Coolpi 4b firmware with buildroot:

@jack_admin
coolpi-sdcard.img 也能通过balenaEtcher 烧录进emmc里面?
烧录的时候选这个镜像就行了是吧

对的

@jugg 通用的

@jugg coolpi-sdcard.img就是自动生成的

@Orion 直接裸操作/sys/class/gpio，不做二次包装

@jugg 可以看下脚本内容，是不是有重启次数

@Orion C++可以代码文件操作gpio，不需要调用python库

@jugg 是直接断电？文件拷贝解压后，最好sync同步一次

@JohnConnor 没有标识型号。说免驱，一般都可以找到驱动支持

@zensation 具体信息提示是什么样的

@asdf 用我们提供的内核编译，相应目录做链接即可。

@zensation make a new boot disk with newest image. also you can fuse system image to emmc through ums mode.

@qys2022 是的。也可以直接在板子上编译测试。

@qys2022 下载内核源码，里面有dts源文件。禁用复用功能，使能对应的串口

@murraytodd thanks!

@Pharizna The partition may not be detected, try formatting emmc or tf card.

@Pharizna ubuntu,armbian and android can be normal using wifi&bt.

@Pharizna said in cool pi 4b RebornOS support:

@george Armbian, for example

I'd like to test Android or OpenEuler, for example ... but I don't know how to install "preinstalled" images .

It seems is not enough to use BalenaEtcher to create a SD/TF to start/run. Help?

Android firmware can be used with Etcher now. Please use the latest download link onedrive or 百度网盘.

@murraytodd please refer to this topic.

@murraytodd that's okay.

@Pharizna
install online through ethernet and restart system.

@bg8wj
更新到新镜像或使用新内核编译替换

@Tourists-0

参考修改内核设备树文件，举例使能can1

vim arch/arm64/boot/dts/rockchip/rk3588s-cp4.dts

&can1 {
        pinctrl-names = "default";
        pinctrl-0 = <&can1m1_pins>;
        status = "okay";
};

@Pharizna
wipe or format emmc and sd partition and try again. also can use udisk boot for auto install ubuntu system.

Themes suggest.
