@george how could you explain how I could connect the Quectel RM500Q-GL 5G modem? I finally got around to purchasing the components for my tablet build and just received them. The Wifi module already occupies the A/E key M.2 slot, and I'm hoping to add an SSD to the other SSD M.2 slot. Are there enough lanes available on the M.2 slot to split for an SSD and the 5G modem?

@petabyte thats very cool, is there an image ready to test? or can i build one?

Okay i managed to build an image but flashing to the board hasnt worked for me yet, how did you go about it?

@Momo-0 any help is appreciated

请问可以也发我一份资料吗？ 下载链接提供的模型，输出也有乱码问题。 我又尝试了下自己转换，但是rknn-llm安装whl也有问题，提示utf8编码无法解码文件。

@george 您好，我又确认了一下，在用systemctl关闭rkaiq的服务之后，读取/dev/video11就是正常的未经isp处理的图像，颜色非常暗，然后开启rkaiq_3a_server之后图像就是全黑的，使用v4l2抓图像是没有读出来数据，感觉不像是读出来了全黑的图

去年同样操作过，没问题，今年买了两台新的CM5，发现运行软件一直警告，无法解决
详细对比了去年和今年版本的差异，发现去年系统版本是

Linux coolpi 5.10.110 #2 SMP Sun Dec 22 10:43:41 CST 2023 aarch64 aarch64 aarch64 GNu/Linux

而新机器的版本是

Linux coolpi 5.10.110 #2 SMP Sun Dec 22 10:43:41 CST 2024 aarch64 aarch64 aarch64 GNu/Linux

有新老版本的差异，在尝试各种方式安装kernel无果，尝试备份老机器后，还原到新机器中也无法开机后，重刷了2023版本的系统，重装系统后运行正常。
最后，需要请教一下，新老版本在preemption model上有无差别？

After letting the Laptop rest for a few days, the cam was back shortly, went away after a few seconds though.

@jugg
是的！通用的。

镜像写入U盘以后，默认就会从U盘启动，你可以去掉EMMC和TF卡模块，机器就会正常进入桌面。

Yes i see it in the schematics now. You are right.

Usually with rk3588 boards You connect the usb-c port with a usb - usb-c cable to the laptop usb-a port and flash it in maskrom mode.

My mistake was not to fully study the schematics. In the schematics i see the OTG port is wired to a USB 3 A port.

I had connected the usb-c to my computer with usb-c to usb A cable and did feed separately 12V to DCIN.

12V DC in is directly wired to the USB-C port pins. no reverse protection on the usb-c port.

I added now a diode similar to the DCIN diode. now can never happen again.
See attached image. this my change for future proof.Bildschirmfoto vom 2024-12-06 00-01-38.png

I will prepare a updated documentation and send it to You george in a private message so You can update the wiki page and the getting started page.

改造后
环境温度： 20度 （室内温度计）
开机温度 ：31.5度
开机10分钟后温度：35.2度
测试chrome 浏览器播放腾讯视频1080p 1小时后温度：43.5度

@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。

@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。
https://github.com/coolpi-george/coolpi-kernel

@george 终于可以了，把系统删减到14个G，就可以用U盘拷贝了，但是使用脚本的方法还是不可以，后面再研究了。谢谢解答👍

@george 有集成最新NPU驱动的固件么？

@george
这是6.1的内核
已有的程序是不是都要重新编译 链接的第三方库也要更新吗

@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

@berkaroad That's sad.
Actually, Kernel 5.10 on the Armbian is quite okay.
But I dont know why when I tried Xonotic, it's very laggy.
I tried to install GPU support by following solution in the webboard.
But still got like 10 FPS.
So, I think updating the kernel could help.

@george 内核启动设置了ipv6.disable=1，今天发现wifi突然断开后无法重连，禁用wifi后再启用也无法恢复，重启电脑后正常。（新问题）

查看日志如下： journalctl -xeu wpa_supplicant

补充一下
使用摄像头为 imx339

输入
gst-launch-1.0 v4l2src device=/dev/video20 ! image/jpeg, width=1920, height=1080, framerate=25/1 ! jpegparse ! mppjpegdec ! videoconvert ! fpsdisplaysink signal-fps-measurements=true sync=false
可达到60帧

加上sudo执行
sudo gst-launch-1.0 v4l2src device=/dev/video20 ! image/jpeg, width=1920, height=1080, framerate=25/1 ! jpegparse ! mppjpegdec ! videoconvert ! fpsdisplaysink signal-fps-measurements=true sync=false
只能达到22帧左右

@emtohere I have the same problem. Only Armbian will boot. No other image works on TF card or USB drive.

@george 好像还有一个backup.fs跟文件系统，我如何烧写进板子呢？
