航模的电源范围？

@wzy
已经在处理CM5-EVB和CP4的支持。

@berkaroad
请帮忙确认一下固件版本？

@dark-road42719
The system is already automatically uploading OneDrive, please confirm later.

@王猛龙 目前4B 32G内存缺货，只有笔记本可以支持32G内存，dewpin理论可以支持。参考论坛制作文件系统的帖子。
TF卡正常没有容量限制，仅和文件系统相关。

@王猛龙 目前没有做deepin的适配，原理上是可以支持的，内存卡理论没有容量限制，只和文件系统相关。

Resolve audio issues with the 6.1 kernel

sudo tar -zxvf rk3588-es8316.tar.gz -C /usr/share/alsa/ucm2/Rockchip/

rk3588-es8316.tar.gz

@plumlis 系统上alsa的配置要修改。镜像已经上传到百度网盘。

@wzy
下周4b和CM5-EVB会同步更新。

• Customize the kernel using 6.1.75
  
• NPU driver updated to 0.9.7
• Support rkmpp video hardware decoding, with a maximum resolution of 8KP60
  
• Delete default username and password, register upon startup
• GPU driver defaults to using Panfrost

@wzy
If using a CM5-NOTEBOOK machine, there is currently a 6.1 kernel available, and the NPU driver is the latest version that can run RKLLM applications. The address is as follows:

The 3.5mm headphone jack has output and MIC functions.

@nosorrow
我们提供的是纯净版，基础的一些包可以自己用命令安装，比如git

sudo apt-get install git

@nosorrow
这个大概率是源服务器问题，可以换其它源试试。

@weiweiwei
具体操作的是哪个GPIO，截图出来看一下，这种控制不到的问题大概率是这个口没有工作在gpio模式。

@plumlis
At present, the mainline kernel is stuck in the edp driver. Due to significant changes in the display framework, the workload of porting is huge. The mainline kernel can be used in subsequent updates.

@plumlis
Refer to the following link to compile and install.

发规格书看看，具体是什么东西？

The partitioning situation of the Coolpi image file is as follow

• The first partition has a size of 512M and a partition format of fat32, used to store boot- files. The default boot mode is extLinux.
• The second partition is the file system, with different sizes depending on the distribution. The partition format is ext4. The label of the partition is writable, which needs to be consistent with the configuration information under extLinux.
  
• The file of the boot partition is shown in the following figure, which you can access through/ The build kernel. sh command compiles the coolpi kernel, and then the files in the out directory need to be copied to the boot partition.
  
• The content is as follows extlinux.conf，Pay special attention to the loading method of the file system, which is searched through label (writable). Of course, it can also be modified to UUID or other types.

default Linux coolpi

label Linux coolpi
	kernel /Image
	initrd /initrd.img
	fdt    /rk3588-cpcm5-notebook-v20.dtb
	append root=LABEL=writable rw rootfstype=ext4 console=ttyS0,115200n81 quiet splash plymouth.ignore-serial-consoles vt.global_cursor_default=1 irqchip.gicv3_pseudo_nmi=0 net.ifnames=0

Start creating a mirror image

• Create an 8GB img file using the following command. Then partition and format.

LOOP_NUMBER=$(losetup -f)
dd if=/dev/zero of=./coolpi.img bs=1M count=8192    
printf 'n\np\n1\n32768\n1081343\nn\np\n2\n1081344\n16777215\nw\n' | fdisk ./coolpi.img   
partx -a -v ./coolpi.img      
mkfs.vfat $LOOP_NUMBER"p1"      
echo 'yes\n' | mkfs.ext4 $LOOP_NUMBER"p2"   
e2label  $LOOP_NUMBER"p2" writable

• Copy files to boot partition，kernel-dir is the file directory corresponding to the Coolpi kernel.

mkdir ./mnt
mount $LOOP_NUMBER"p1" ./mnt
cp  kernel-dir/out/* ./mnt -r
umount  ./mnt

• Create a file system, Add rc.local file to automatically expand partitions and configure some system node permissions.

wget https://mirrors.aliyun.com/archlinuxarm/os/ArchLinuxARM-aarch64-latest.tar.gz
mkdir ./archlinux
tar -zxvf ArchLinuxARM-aarch64-latest.tar.gz -C ./archlinux/
mount $LOOP_NUMBER"p2" ./mnt
cp -rf ./archlinux/* ./mnt/ 
tar -zxvf  kernel-dir/out/modules.tar.gz -C ./mnt/lib/
cp ./rc.local  ./mnt/etc/
umount ./mnt
e2fsck -p -f $LOOP_NUMBER"p2"
resize2fs -M $LOOP_NUMBER"p2"
losetup -D $LOOP_NUMBER

目前的大容量电池厂家给的最小起订量是3K，交期要2个月，认证还要45天。众筹的这个来不及上大容量电池了。只能后续作为配件再升级了。
