Allwinner A133 Usb Driver |link| -

The Allwinner A133 (also known as sun50iw10 or R818) is a quad-core 64-bit application processor widely used in mid-range tablets and smart displays. To interface with this hardware via a computer for firmware updates, debugging, or rooting, specific USB drivers are required depending on the device's operational mode. 1. Hardware Interface Overview

  • USB 2.0 full/hi-speed controller (DWC or vendor-specific variant)
  • OTG support (host/device role switching) via ID pin and controller
  • External PHY or integrated UTMI/ULPI interface depending on board design
  • VBUS power control via GPIO or regulator controlled by driver

3. Linux Kernel Driver (Mainline vs. BSP)

Mainline (good for custom Linux)

  • Uses dwc2 driver + sunxi glue.
  • Stable for host mode (mass storage, HID, Ethernet).
  • OTG detection works but may need correct device tree configuration.
  • FEL mode is not a Linux kernel feature – it’s ROM‑based. The kernel driver only matters once the OS boots.
