@顾真牛 4B和CM5软件使用习惯是一致的。

@顾真牛 预计2月中旬左右。

@顾真牛 你期待哪个版本的UOS？专业版？

@顾真牛 系统切换是支持的，这部分可以在boot分区修改extlinux.conf文件实现。理论上用户自行创建多个rootfs分区，通过相应分区label区分，切换系统也比较容易实现。

当然uboot源码我们也是开放的，大家都可以根据需要修改

@bg8wj 谢谢！我们验证好了会同步发布出来。这款主板还有很多功能可以挖掘，需要更多的伙伴一起共赢！

@macthree 有部分GPIO支持硬件PWM功能，当然也可以用GPIO模拟PWM功能。

When system (like ubuntu desktop) is running, we can press power key to poweroff system or restart system.

if want to skip select option, you can set in the terminal shell:

coolpi@coolpi:~$ gsettings set org.gnome.settings-daemon.plugins.power power-button-action interactive

coolpi@coolpi:~$ gsettings set org.gnome.SessionManager logout-prompt false

@bg8wj github已更新内核驱动代码。二进制执行文件明天测试好再上传

@bg8wj 需要更新内核驱动

@bg8wj
先确认系统是否识别到摄像头模组

dmesg | grep ov564

是用系统自带的相机茄子？该软件需要配置，另外摄像头效果文件还需要额外的应用导入，晚些打包到系统中。

@nickliu Thanks! While burn firmware and insert eMMC or TF card first booting, please save serial console log.

@nickliu https://www.cool-pi.com/topic/168/如果制作的启动盘无法加载

Maybe like this. Do you have TF card which can load into system?

OV5647模块适用于Cool Pi 4b

Use buildroot system image for test camera ov5647.

@nickliu emmc onboard also nice！

change console to ttyS1, and then boot again if something output message from HDMI.

@nickliu I'v check these images and boot okay.

@lymnxn 手动挂载更新。后续发布再合入

@retroman Bluetooth feature has been added to support. I will upload a new image file (20230118) to onedrive.

@dreamer

uart2 node is used for console and uart9 node is used for bluetooth.

@bbsvs2000
禁用rkisp、cif、csi
rk3588s-cp4.dtb

用于加载/boot/firmware/wifi.txt
wifi_precfg

sudo cp rk3588s-cp4.dtb /boot/firmware/rk3588s-cp4.dtb

sudo cp wifi_precfg /usr/sbin/

sudo chmod a+x /usr/sbin/wifi_precfg

sudo reboot

为方便将emmc模块当做TF卡使用，我们设计了转接小板。配合读卡器，可以当做一个移动U盘使用。

如果转接小板不能很好插入读卡器，请磨平如下箭头标识位置后，再测试。

Burn system image to ssd and load from usb3 port!

百度网盘下载更新loader固件20230207

USB外接SSD硬盘，对电源适配器有要求，至少5V/3A！
好用！推荐这种方式

@retroman Not only. Thanks!

@bbsvs2000 usb-hub电源适配器拍照看下。另外摄像头直接连接主板也试下功能是不是正常的

@bbsvs2000

看log有部分错误信息。将外挂的usb-hub接到蓝色USB3端口试试

@dreamer
hi, please add extra operation for coolpi user.

Add rules for normal user:

sudo echo "SUBSYSTEM==\"gpio*\", ACTION==\"add\", PROGRAM=\"/bin/bash -c 'chown root:coolpi /sys/class/gpio/export /sys/class/gpio/unexport;chmod 220 /sys/class/gpio/export /sys/class/gpio/unexport'\"" > /lib/udev/rules.d/99-gpio.rules
sudo echo "SUBSYSTEM==\"gpio*\", ACTION==\"add\", PROGRAM=\"/bin/bash -c 'chown root:coolpi /sys%p/direction /sys%p/value /sys%p/edge /sys%p/active_low; chmod 0660 /sys%p/direction /sys%p/value /sys%p/edge /sys%p/active_low'\"" >> /lib/udev/rules.d/99-gpio.rules
sudo reboot

Check rules:

coolpi@coolpi:~/Desktop$ cat /lib/udev/rules.d/99-gpio.rules 
SUBSYSTEM=="gpio*", ACTION=="add", PROGRAM="/bin/bash -c 'chown root:coolpi /sys/class/gpio/export /sys/class/gpio/unexport;chmod 220 /sys/class/gpio/export /sys/class/gpio/unexport'"
SUBSYSTEM=="gpio*", ACTION=="add", PROGRAM="/bin/bash -c 'chown root:coolpi /sys%p/direction /sys%p/value /sys%p/edge /sys%p/active_low; chmod 0660 /sys%p/direction /sys%p/value /sys%p/edge /sys%p/active_low'"

Test case:

coolpi@coolpi:~/Desktop$ echo 115 > /sys/class/gpio/export 
coolpi@coolpi:~/Desktop$ ls /sys/class/gpio/gpio115
active_low  device  direction  edge  power  subsystem  uevent  value
coolpi@coolpi:~/Desktop$ echo out > /sys/class/gpio/gpio115/direction 
coolpi@coolpi:~/Desktop$ echo 1 > /sys/class/gpio/gpio115/value 
coolpi@coolpi:~/Desktop$ echo 0 > /sys/class/gpio/gpio115/value 
coolpi@coolpi:~/Desktop$

@bbsvs2000

提供以下命令输出

lsusb
lsusb -t
dmesg

用自带相机能打开几个摄像头
