Table of Content

A list of special device files (2.4 / 2.6 kernel only!)

The 2.4/2.6 kernels expose some old-style /proc interfaces

  • /proc/jz/numlock_led - write 0 or 1 to the LED
  • /proc/jz/capslock_led - write 0 or 1 to the LED
  • /proc/jz/eth0_led - write 0 or 1 to the LED
  • /proc/jz/battery - reads battery flag
  • /proc/jz/battery-level - reads battery status
  • /proc/jz/wifi-power - write 0 or 1 to power up WiFi
  • /proc/jz/backlight - write value to backlight PWM (0..300)

  • /proc/powerdown

  • Touch screen position

  • Touch screen keys
  • Keyboard events

This all will be replaced by modern API in the Letux-kernels >4.13
