Environment configuration

You need install some packages before building.
Ubuntu 14.04:

$ sudo apt-get install git-core gnupg flex bison gperf build-essential \
				zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
				lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
				libgl1-mesa-dev libxml2-utils xsltproc unzip qemu-user-static \
				qemu qemu-system

Build

• $ make all
  use for first build
• $ make base
  build kernel/demo/hardware
• $ make kernel
  just build kernel
• $ make ubuntu-base
  just build ubuntu-base image
• $ make lubuntu-core
  just build lubuntu-core image

Flash Image

$ sudo ./tools/DFU/linux/upgrade_tool ul output/image/RK3188Loader(L)_V2.19.bin
$ sudo ./tools/DFU/linux/upgrade_tool di -p output/image/parameter
$ sudo ./tools/DFU/linux/upgrade_tool di -k output/image/kernel.img
$ sudo ./tools/DFU/linux/upgrade_tool di -b output/image/boot.img
$ sudo ./tools/DFU/linux/upgrade_tool di -s output/image/lubuntu-core.img
$ sudo ./tools/DFU/linux/upgrade_tool rd

If you use eMMC storage, you need flash parameter.emmc:

$ sudo ./tools/DFU/linux/upgrade_tool di -p output/image/parameter.emmc

Demo

• GPU

  glmark is a benchmark for GPU， you can use it in lubuntu-core firmware, open an terminal and input:

  sudo glmark2-es2
  

• Video Decode&Encode

  We provide testvpu tools for H264 encode & decode, it's code in demo/vpu_api_demo/。

  • Video Decode
    Input H264 data, output yuv(nv12) data：

  sudo /root/testvpu -i ./h264_320x240_coding_7_for_dec.bin -o ./test.yuv -w 320 -h 240 -coding 7 -vframes 60

  Note: at the beginning of each frame, 4 bytes are used to indicate the length of the frame.
  * Video Encode  
  	Input yuv(nv12) data, output H264 data:
  

  sudo /root/testvpu -t 2 -i ./vpu_enc_input_yuv420sp_320x240.yuv -o ./test.bin -w 320 -h 240 -coding 7

• Camera

  • UVC Camera We use luvcview tools for camera preview:
    1. Plug-in USB Camera， we will find a video device at /dev/，like /dev/video1.
    2. run command:

    luvcview -d /dev/video1 -f yuv -s 320x240
    

  • CIF Camera We provide testcamera for cif camera:

    sudo /root/testcamera
    

    It will open cif camera and output data to camera_640x480_nv12.yuv

• RGA

  We provide testrga for image scale and codec translate：

  sudo /root/testrga
  

  Input NV12 file: in_1920x1088_nv12.yuv, output ABGR file: out_1920x1080_ABGR.yuv。

• Audio

  We use alsa tools for audio control. playback test:

  aplay /usr/share/sounds/alsa/Front_Center.wav
  

  record test:

  arecord -f cd -d 10 -t wav /tmp/test.wav
  aplay /tmp/test.wav
  

  play mp3 file：

  play sample.mp3
  

• Ethernet

  We use ifconfig to turn on/off ethernet.

  ifconfig eth0 down
  ifconfig eth0 up
  dhclient eth0
  

• WIFI

  Use wpa_cli application to control wifi AP Scanning:

  wpa_cli scan
  sleep 3
  wpa_cli scan_result
  

  Add network:

  wpa_cli add_network
  wpa_cli set_network 0 ssid \"Rockchip-XXX\"
  wpa_cli set_network 0 psk \"XXXXXXXX\"
  

  Delete network:

  wpa_cli remove_network 0
  

  Select network:

  wpa_cli select_network 0
  dhclient wlan0
  

  Enable network

  enable_network 0
  

  Disable network

  disable_network 0
  

  You can write the network info to /etc/wpa_supplicant.conf for auto connect. like:

  network={
    ssid="AP name"
    psk="Password"
  }
  

• backlight contorl

  Manually set backlight

  sudo echo 60 > /sys/class/backlight/rk28_bl/brightness
  

  Auto set backlight： add below command line to /etc/rc.local file

  echo 60 > /sys/class/backlight/rk28_bl/brightness
  

• SD Card and USB disk.

  Plug-in SD card and mount it:

  mount /dev/mmcblk1p1 /mnt
  

  Plug-in USB disk and mount it:

  mount /dev/sda1 /mnt
  

  umount SD card or USB disk:

  umount /mnt
