WS217 (RTL8811) RASPBERRY PI

Попробовал завести модуль WS217 (чипсет RTL8811) на Raspberry Pi Zero W.

По умолчанию образ Raspbian OS Stretch (kernel 4.14.52+) не поддерживает драйвера для этого модуля.

Использовал драйвера с github:

• https://github.com/Rajpratik71/Realtek-rtl8811AU_8812AU_8821AU_linux-source-code
• https://github.com/sloretz/rtl8811au

Заметка основана на материалах:

2. https://gist.github.com/awesomebytes/196eab972a94dd8fcdd69adfe3bd1152 (исходная инструкция)
3. https://github.com/ros-infrastructure/ros_buildfarm/blob/master/doc/custom_rosdistro.rst (статья про использование кастомных зависимостей rosdep в rosbuildfarm)
4. https://answers.ros.org/question/230104/using-bloom-to-generate-binaries-for-multiple-packages/ (вопрос про билдинг нескольких пакетов)
5. https://answers.ros.org/question/292024/how-to-use-bloom-generate-with-private-dependencies/ (статья про билдинг с кастомными зависимостями)
