编译u-boot
暂时未测试是否可用
2022.4.14测试发现 生成的spl/sunxi-spl.bin 无法刷入
执行 sunxi-fel spl spl/sunxi-spl.bin 会出现usb_bulk_send() ERROR -7: Operation timed out
但macromorgan的可以刷入,这就很奇怪……

You cannot build libraries for Android with the following steps.

1、安装msys2配置系统环境变量Path添加 C:\msys64\usr\bin
执行 pacman -Su
执行 pacman -S git patch unzip
2、安装Python3.9.10 勾选系统环境变量 执行pip install numpy --user
3、安装VS2019,勾选使用C++的桌面开发
4、下载bazel-5.0.0-windows-x86_64.exe 重命名为bazel.exe 并配置系统环境变量
设置Bazel变量
set BAZEL_VS=C:\Program Files (x86)\Microsoft Visual Studio\2019\Community
set BAZEL_VC=C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC
set BAZEL_VC_FULL_VERSION=14.29.30133
set BAZEL_WINSDK_FULL_VERSION=10.0.19041.0
5、下载nuget 并配置系统环境变量
6、下载opencv-3.4.16-vc14_vc15.exe 运行解压在C盘根目录
7、Android Build Tools<31 Android NDT <22 配置系统环境变量sdk ANDROID_HOME ndk ANDROID_NDK_HOME
步骤7不需要,该工程无法创建Android libraries

最后MediaPipeUnityPlugin工程目录下执行 python build.py build --desktop cpu --opencv=cmake -v
编译
Unity编辑器运行

原文地址https://blog.omgmog.net/post/pocket-chip-global-volume-control/

The original one was running a relatively heavy shell script (/usr/sbin/battery.sh) outputting many battery-related parameters in order to grep only 2 (voltage and charging status) and put them into two files that were later used by other scripts and even the default home screen program.

sudo apt-get install libx11-dev libxtst-dev git gcc make
git clone https://github.com/aleh/pocketchip-batt.git
cd pocketchip-batt
sudo make install

If you want to undo the changes:
sudo make uninstall

pocket-home appears to be constantly consuming up to 1-4% of CPU, must be polling something fairly hard, would be great to patch it. I've personallly moved to JWM, see https://github.com/aleh config https://github.com/aleh/pocketchip-jwmrc .
