OrangePi 2G-IOT support ADB mode, it's helpful on non-screen mode.

So this section will introduce how to use adb on OrangePi 2G-IOT.
Note! OrangePi 2G-IOT can't support "USB host" and "OTG" at the same time.


First of all, change swith to select 'adb' mode, as follow:
The "1234" are "UP" and "5678" are "DOWN"


Then, configure adb on Linux or Windows.
If you haven't configure adb on your machine, please refer article on web.

Connect OrangePi 2G-IOT to PC with usb-cable


Next, use adb command to connect.
  1. adb devices
  2. adb root
  3. adb shell
Copy code

The last, utilize "Vysor" from chrome plug-in.
More article introduce how to install "Vysor" on Linux or Windows.

"Stock" 2G-IoT NAND Android (at least for boards shipped in April) comes with Development ->USB debug option disabled.
It is kinda tricky to enable it with serial connection and manual edit of filesystem files - but is possible.

Hi,

thanks in advance for the information.
I have a couple of questions:
1) The board comes with a ROM in the internal NAND already for use or I need to flash it first?
2) The default WIFI "OrangePi" are configurated in Android OS, Armbian and Debian Server?

Thanks!

  1. C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
  2. List of devices attached


  3. C:\Program Files (x86)\Minimal ADB and Fastboot>adb root
  4. adb: unable to connect for root: no devices/emulators found

  5. C:\Program Files (x86)\Minimal ADB and Fastboot>adb shell
  6. error: no devices/emulators found
Copy code


Well... it seems that it's not working for me... I have the pin in nand mode, the switches as indicated in the post it's and connected to the computer by the micro-usb (which gives power to it too). The board has a red light on though...And I can hear the "device connected" sound in windows, but nothing appears in the windows explorer, neither in the device administrator (only "Android ADB interface")

I am using the latest firmware, the board is recognized in windows 7 as Google Nexus 7 ADB Interface. Command line "ADB Devices" result in empty list of "List of devices attached". Any help ?

I have the same problem.
Connect the usb OTG to my windows PC and only appear RDA Phone like MTP device. Try to enable the USB debugging connecting to TTL debug pins with and TTL-USB cable like user manual show and i followed this steps:
Let it be simple (root possibly[1] required):
settings put global development_settings_enabled 1settings put global adb_enabled 1And then you need to
echo "mtp,adb" > /data/property/persist.sys.usb.config

(https://android.stackexchange.co ... -using-command-line)

Then i have luck and automatically appears an ADB interface in the device manager, the Vysor app detect the phone but when i try to connect says me something related with the RSA verification. If i could view the display then i could easily tap on YES to authorize the device, but i have not an screen.
Also i tried to reboot the board and after this, the Android doesn't boot anymore, in a few hour i can post the log. Even i try to update the Android NAND but i have not luck with that.
The steps I followed are:
1) Download and install tool, drivers and Android NAND bin.
2) Set jumper cap to boot from NAND and toggle switch 1234 UP 5678 DOWN.
3) In the writing tool, load bin image and press "Download", the soft says that wait for download link.
4) Connect with an USB cable the OTG port with the PC.
5) Push the power button for 5 seconds
6) And nothing happens.

Why have they disabled the USB debbuging from default?
I have not had a good start with this board. Hope i can make it work.
Regards!

You have the USB debugging enable or have you had to enable it?
Have you tried installing different drivers?
This installer has good references: 15 seconds ADB Installer

Good luck!

It was enabled by default in the new firmware, although before that I took the same steps as you did for the old firmware (before upgrading to the new one, unfortunately I had no lcd screen back then so cannot verify the key). Now I have the lcd screen but problem with the adb. I tried the ADB installer but it did not recognize the phone. I will try a few different things & will let you know the results.
