ADB shell with RK3066

From Linux Rockchip
Jump to: navigation, search

TODO: clarify this is not just for RK3066, make better notes about some devices needing to continually re-enable usb debugging, using "adb devices" to check if it's in the right mode

You need to add those Udev rules in order to obtain an ADB shell on your RK3066/RK3188 device:

  • Log in as root, and list the content of your USB bus with "lsusb", you should see a device with a device ID starting by "2207", the USB VendorID of Rockchip:
$ lsusb
Bus 002 Device 023: ID 2207:0010
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

In this case, the description of the device (a Vido N70 tablet in this case) was left empty.

  • Download and install the Android SDK. Or, alternatively, just download adb from an Ubuntu Linux with this command:
  sudo apt-get install android-tools-adb
  • Log in as root and create the file "/etc/udev/rules.d/51-android.rules" with the following content:
SUBSYSTEM=="usb", ATTR{idVendor}=="2207", MODE="0666", GROUP="plugdev"
  • As root, restart udev with "udevadm control --reload-rules"
  • Log in with your normal unix user, and edit ~/.android/adb_usb.ini, add 0x2207 at the end of the file
  • As user, restart the adb server with "adb kill-server; adb start-server"
  • As user, you should be able to list your device with "adb devices"
  • And finally, get a shell on the device if you have activated "USB Debugging" on Android:
$ adb shell
root@android:/ # cat /proc/cpuinfo
