测试如下核心板位置，关机的状态下电源是否正常？

@jugg
你用的CM5-EVB？在哪里增加了电池？

@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。

@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.

@jugg
使用这份内核试试

@young2024
如果需要比较新的NPU驱动，建议内核更新到6.1，百度网盘最新的24.04镜像已经默认使用6.1版本内核。

仔细看看脚本的代码，搞清楚备份的步骤，肯定可以操作成功的。

@jugg
如下命令就会生成头文件目录，拷贝到系统usr/src/linux-headers-5.10.110目录即可

make ARCH=arm64 headers_install INSTALL_HDR_PATH=out_headers/usr/src/linux-headers-5.10.110

@Twsuts-0
从log信息看还是文件系统拷贝的不正确。不行就直接手动操作好了，参考脚本的命令。

@Twsuts-0
8192是8G ,30G改为30720

@Twsuts-0
脚本具体镜像大小要修改一下，28G的数据DD的镜像尺寸至少要30G.默认脚本的8G镜像大小不合适。

@Twsuts-0
你不能工作的启动信息有没有，发一下。

@Twsuts-0
参考如下附件backupimg.sh

@rtmtree
As shown in the figure below, this control chip only supports the SATA3.0 protocol.

@rtmtree
Confirm the specific model of this chip and send it out for me to check the specification sheet.

@Momo-0
Confirm that the USB camera device has not been recognized, and verify if other images are functioning properly or if all images are no longer recognized properly. If so, there may be hardware abnormalities.
When the machine is powered off, unplug the LCD cable again. The USB signal of the camera is connected to the LCD cable.

@rtmtree

1. Confirm that SSD supports NVME protocol, SATA machines cannot support it
2. ls /dev confirm if any nvme devices have been found
3. Use commands to format the hard drive

sudo mkfs.ext4 /dev/nvme0*

@Momo-0
Please confirm which image you are using, and you can also use the following command to view the USB device:

lsusb

@rtmtree
The 8MB is SPI-NOR memory, which stores bootloader and UBOOT internally. If the disk is formatted, it will not start properly. Don't worry, just update the image again. Provide an update method later.
