@george 我的网络不能git文件

@george 👍

@jugg 更新系统不会破坏loader文件。不需要重新升级loader。

@Mz3D-0 Both CP4 and CM5 already support 32G/256G configurations and can be purchased directly from an agent.

@顾真牛 改为动态分频测试一下

@wuming 百度网盘有镜像，可以用u盘安装系统

@edwardzhou 用U盘备份安装系统，不用考虑移除emmc

@george 不错不错 银子准备好了 就看你们啥时候出了

@george
gstramer的硬件解码插件叫什么 只有openh264dec ?

@wuming 可以尝试按照下面帖子步骤处理：

@retroman Has been updated, please check.

@AugustRobot_Zou said in How to upgrade the boot loader of coolpi 4b？:

Since I upgraded my PC to Win11, the RKDevTool always cannot find the device of coolpi-4b.
Does the RKDevTool support Win11?
Or could I upgrade the boot loader of coolpi-4b in ubuntu environment?

https://www.cool-pi.com/topic/47/coolpi-4b-bootloader命令行升级方法

用这个办法升级成功，避开RKDevTool 在win11驱动问题

@大法师
有什么命令可以在ssh进入系统后 也能随时查看这些系统参数
温度、ip这些
