Software Environment

  • Based on OpenWrt BARRIER BREAKER (Bleeding Edge, r41508)
  • rt2860v2 Wi-Fi driver hacked by lintel
  • Customized uboot hacked by manfeel
  • WRTnode aplci up-link Wi-Fi configuration (aps/vw/nr/ia)
  • Luci Wi-Fi wpa patch for rt2860v2
  • Local dns add i.wrtno.de & wrtnode.lan besides openwrt.lan to WRTnode which the default ip is
  • WRTnode additional feature (all source opened github.com/WRTnode):
    • Opencv 2.4.8
    • Native gcc-mipsel on mt7620 and bin-utils
    • Porting linino (Arduino yun) source to WRTnode
    • Shine: fast fixed-point mp3 encoding
    • And some WRTnode demo apps:
      • opencv application demo
      • mechanical control demo
      • RESTful front-end demo and some other thing

WRTnode firmware, SDK and cross-compiler toolchain using OpenWrt trunk version, designed for WRTnode maintenance and support by OpenWrt.org official. Meanwhile, WRTnode can use the market all the programs using the MT7620 router firmware and associated SDK and cross-compiler toolchain.
