@bbsvs2000 可以支持。更新内核配置加上即可

@bbsvs2000 安装内核驱动包再试下鼠标是不是会消失
debug鼠标消失

sudo dpkg -i coolpi-kernel_1.0.0_aarch64.deb
sudo reboot

除X86架构外，本次0.9.5版本全新解锁ARM架构，官方适配Raspberry Pi和Cool Pi开发板，支持树莓派软硬一体的开发模式，打破开发边界，发掘无限可能。

openKylin官方发布

https://www.cool-pi.com/topic/164/coolpi-4b-openkylin-0-95-version-support

测试镜像固件下载地址 20230114-openkylin-0.95-preinstalled-arm64-coolpi.zip

default user name coolpi, and passwd coolpi

apt install firefox
apt install kylin-video
apt install hardinfo

@bbsvs2000 晚点我更新一个版本。或者你从github上取内核，重新编译替换试试

@bbsvs2000 烧录校验一般问题不大。不排除读卡器和tf卡质量因素导致的校验

@bbsvs2000 看起来驱动都是正常加载的。只是wifi图标不见了？有没有安装其他组件导致的呢？

@bbsvs2000
lsmod查看驱动加载状态
ifconfig -a 有无wlan0接口
dmesg log导一份上传

@bbsvs2000
系统刷机是格式化写入的。重要文件备份保存

上周有新版本，刷个新的系统试下

系统补充安装libvirt相关组件

sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virtinst virt-manager

sudo reboot

@retroman
also use onedrive link(https://1drv.ms/u/s!AhSBNZjrDPlSanDDQF7WowYhiz8?e=lRpMrk). And then the top u3 port is used for adb debug.

SX1302是新一代用于网关的基带LoRa芯片。它的优点是降低电流消耗，简化了网关的热设计，并降低了材料清单成本，但它能够处理比之前的设备更高的流量。

@retroman which image you loaded?

@retroman use adb command and change cmdline.txt (delete console=ttyS0) which in boot partition.
Or wait for next version image.

@retroman
hi, thanks for your advice. This work will be long and continue. We need more community friends to participate.

RKDevTool_Release_v2.92_loader0104.zip

You can try refuse loader program and check if display coolpi logo.

@retroman please use coolpi firmware. Don't fuse other image that will damaged hardware.

@zensation check your firmware version, please use latest ubuntu22.04 for testing.

Use Rkdevtool or upgrade_tool for fuse emmc 百度网盘 or Onedrive

the firmware only for running debug.

参考
https://www.cool-pi.com/topic/138/coolpi-4b-led-red-green-control-example

板载两颗led灯，均可以软件操作亮灭以及闪烁，参考如下：

echo 0 > /sys/class/leds/led1-r/brightness
echo 255 > /sys/class/leds/led1-r/brightness
echo none > /sys/class/leds/led1-r/trigger
or
echo timer > /sys/class/leds/led1-r/trigger

download and install with root user.

sudo pip3 install CPi.GPIO-1.0.0-cp38-cp38-linux_aarch64.whl

for ubuntu 20.04
CPi.GPIO-1.0.0-cp38-cp38-linux_aarch64.whl

for ubuntu 22.04
CPi.GPIO-1.0.0-cp310-cp310-linux_aarch64.whl

other
CPi.GPIO-1.0.0-cp39-cp39-linux_aarch64.whl

default gpio cfg with system image:

gpio_coolpi

test.py

running test:

sudo python3 test.py

#!/usr/bin/env python3

import CPi.GPIO as GPIO
import time

PIN = 40

GPIO.setmode(GPIO.BOARD)
GPIO.setup(PIN, GPIO.OUT)

while True:
   GPIO.output(PIN, 0) 
   time.sleep(1)
   GPIO.output(PIN, 1) 
   time.sleep(1)

其中GPIO.setmode(GPIO.BOARD)表示使用coolpi 4b板子自然编号Pin number。如果要使用Rockchip gpio编号，需要引用GPIO.setmode(GPIO.RK)。

if you want to remove this module, exec command:

sudo pip3 uninstall CPi.GPIO
