@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。

Add GPU driver

Add hardware decoding for FFMPEG videos

If you need to boot armbian normally, you need to update the loader file to version 0104.

Follow the steps below to update the loader:

Download the latest loader file One Drive
![5594e1d4-3a7b-46fc-a7b5-2a9fe418dfc0-image.png]
Short the 2 pins shown by the arrow.
The USB interface and computer connection.
Plug in the power supply and open the upgrade software. The machine enters the maskrom upgrade mode.
choose to write by address
Click Execute to complete the loader update.
If the computer prompts that the USB driver cannot be found, please download and install the driver software first.One Drive

Need to cooperate with testing first to determine where the problem lies?

Connect the LCD cable and use a multimeter to test the ground impedance of the two PINs shown in the figure below
Disconnect the LCD cable and use the same method to test the ground impedance of two PINs
Test method: Set the multimeter to the diode position, connect the red probe to GND, and connect the black probe to the signal.

@jugg
CST时间和UTC时间的区别，并不是不能同步。也不是RTC不工作。系统层的问题百度一下。

george

@jugg
从上面的信息能够确认RTC的时间是正常的，关机时候是9:49，再开机是：9:57，只是RTC时间没有同步到系统。
日志也提供了方法：

timedatectl set-local-rtc 0

george

@jugg
1.确认你外部电源供电电压是多少V
2.关机之前查看一下硬件RTC的时钟情况，使用如下命令：

cat /proc/driver/rtc

3.关机一段时间再开机，再次查看硬件RTC时间

cat /proc/driver/rtc

然后把结果发上来。

george

@jugg
测试如下核心板位置，关机的状态下电源是否正常？

george

@jugg
你用的CM5-EVB？在哪里增加了电池？

george

@jugg
原因是系统没有同步RTC的硬件时钟，而不是说硬件RTC没有工作。

george

@Kanade
建议切换到6.1的背个版本。默认的代码会生成一个头文件的包，解压到/usr目录即可。

From the phenomenon, it appears that there is a hardware malfunction, such as a damaged camera module or connector.
If you have a certain hardware foundation, you can provide drawings and methods to guide troubleshooting.
