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