Panthor needs to be loaded in KO mode.

@prcups said in Try to Use Archlinux Arm:

Direct firmware load for arm/mali/arch10.8/mali_csffw.bin failed with error -2

This bin file path needs to be modified.

@etrin
There are many models in the driver kernel source code of the camera, but this can only ensure that the system recognizes the nodes. For the camera part, it is more important to debug the ISP effect file, which is highly specialized and difficult for those who have not been exposed to it to handle.

@Albert
标准的PCIE连接器接入的电压值是12V，先确认TYPEC接口默认诱导出了12V电压。然后可以尝试先使用网卡等设备测试，确保正常工作以后再使用PCIE转SATA的转接板。

@mainbord
The efficiency of the Panthor driver is currently lower, and we look forward to future updates.

@mainbord
The mali_csffw.bin path corresponding to the Panthor driver needs to be modified. The dmesg information will show the new loading path, and copying it on the system will enable GPU acceleration.

@rippanda12
Thank you for your support of Coolpi products. Could you further introduce the features and advantages of the system? We hope to see CM5-LAPTOP products perfect your system.

@plumlis
The function of switching between speakers and headphones is now OK, and the 6.1 kernel has been updated to the latest version.
Then/etc/rc.local blocks the following options：

#amixer -c 2 cset numid=4 192
#amixer -c 2 cset numid=2 4,4
#amixer -c 2 cset numid=13 6
#amixer -c 2 cset numid=19 28
#amixer -c 2 cset numid=20 6

Upgrade the Mesa version according to the following instructions, and then copy the Mali bin file to the corresponding path to enable Panthor.

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo  apt-get  dist-upgrade

@mainbord
At present, the mainline kernel EDP interface is not supported. The CM5-LAPTOP configuration has been submitted for mainline review and should be released soon.

@happyday
默认是DHCP自动获取的，你可以改为固定IP，网上很多资料。百度一下就能解决。

@mez62
好的，抽空弄一个。其实教给大家方法可能会更好，回头写个帖子，就以archlinux作为对象一步一步制作镜像。

@mez62
哎！太苦了，其它人都在干项目。欢迎更多爱好者能够加入一起维护。

@plumlis
是的，需要换回去老的mesa版本。

@plumlis
其它的功能会持续完善，音频 NPU 编解码这些都还有问题。

@plumlis
内核默认启用了panther的GPU驱动，需要先把mesa更新到24.02版本，否则就会黑屏。

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo  apt-get  dist-upgrade

@santu
重启和重新上电以后运行如下命令发出来

ls /dev/ttyS*

@happyday
这个是不一样的，关于DTS的配置参考之前发的文档，或者在rockchip的DTS目录里边找一下对应的配置，其它平台的不适用。

@plumlis
内核需要修改增加驱动支持。应用层驱动已经有各个版本的ppa源支持。

@plumlis
同步最新代码，6.1的内核目前已经可以本机编译。

@happyday
下图是SPI1对应的属性配置，把dmas和dma-names复制到DTS文件对应节点即可。

	spi1: spi@feb10000 {
		compatible = "rockchip,rk3066-spi";
		reg = <0x0 0xfeb10000 0x0 0x1000>;
		interrupts = <GIC_SPI 327 IRQ_TYPE_LEVEL_HIGH>;
		#address-cells = <1>;
		#size-cells = <0>;
		clocks = <&cru CLK_SPI1>, <&cru PCLK_SPI1>;
		clock-names = "spiclk", "apb_pclk";
		dmas = <&dmac0 16>, <&dmac0 17>;
		dma-names = "tx", "rx";
		pinctrl-names = "default";
		pinctrl-0 = <&spi1m1_cs0 &spi1m1_cs1 &spi1m1_pins>;
		num-cs = <2>;
		status = "disabled";
	};

@plumlis
panthor的驱动最近在同步测试，很快就会发布。

@plumlis
当然要和Thinkpad的键盘没法比较，但是确实从来没有收到过键盘会误触 吞键的问题，这套模具我们工厂X86一年几十万台出货量的。如果确实是单体有问题，直接申请售后就好了。这个没关系的。

@plumlis
可以。

@plumlis
目前看是编译环境引起的，编译器的版本问题导致，还在处理中。

@mez62

关于功耗数据这部分，下面数据供参考

• ubuntu22.04主界面电流在500ma左右，
  
• 本地4K高码率视频播放电流在680ma左右
  
• 网络视频播放电流在730ma左右
  
• 待机电流
  8+64配置 7.4V/6ma 32+64配置 7.4V/8ma
• 关机电流
  7.4V/270ua

关于散热处理

目前采用的被动散热方式可以满足正常的办公 娱乐 包括软件开发编译。但是如果一定要CPU长时间工作在满负载状态，那肯定需要主动散热，这个是由RK3588自身功耗决定的，结合目前平板电脑和手机的散热处理方式，日常使用场景被动散热可以满足要求。
从半导体的特性分析，长时间的高温是会缩短CPU的寿命。对于能否用来做主力本，还是要评估使用场景。
机器主板本身是有预留主动散热器风扇接口，这个有条件的话也可以DIY改装，我们可以提供支持。

关于FPGA的连接问题

目前FPC连接器提供以下接口

• PCIe 2.0x1/USB 3.0/SATA 3.0 (pick one out of three)
• 2x USB 2.0 HOST interfaces
• 1x Gigabit Ethernet
• 1x SDMMC 3.0
• UART, SPI, I2C, GPIO
  

Version 6.1 of the kernel requires updating the GPU's bin file by replacing the attached bin file in the system /lib/firmware directory. Otherwise, the old bin file will cause a black screen during system startup.
mali_csffw.bin

@mainbord
At present, the edp function of the mainline kernel has not been debugged yet, and can only output HDMI temporarily. So the LCD is currently unable to display properly. The main line currently has DTS configuration for CM5-EVB, and after comparing it with the updates on Notebook, it can start up normally.
