How to activate USB host mode in Alpine linux?

  • Hello,

    It is usually recommended to directly modify the kernel device tree to achieve this. You can refer to the USB-related WIKI.

    The way to modify dynamically in the system is as follows:

    Code: Select all

    # host mode
    echo host > /sys/devices/platform/ff3e0000.usb2-phy/otg_mode
    # peripheray mode
    echo peripheral > /sys/devices/platform/ff3e0000.usb2-phy/otg_mode
    
    This type of configuration will be lost after a reboot. It can be set by writing a startup script.

    We do not maintain the Alpine Linux image. There might be some background programs that cause the settings not to take effect.
