This is a very rough port, but it's a start:
https://gitlab.futo.org/daniel/edk2-rk3588

This is mostly copy+pasted from the orange-pi 5 port, so a bunch of things still need to be finished/looked over. But I was able to boot a fedora image over ACPI, so it's close to being usable.

I would post a screenshot but this site says 'image dimensions are too big'. So here's a tweet: https://x.com/danielcdev/status/1889075801787716016

@anernest
These features are already supported on laptop products.

@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.

@berkaroad said in 分享被动散热改造:

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

Launch this test for 20 minutes please

@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？
