Re(install) Vivid Unit OS

Vivid Unit has eMMC storage onboard and the operating system (Debian with XFCE desktop enviroment) has been pre-installed in the eMMC. Usually you do not need to install operating system by yourself. However if the operating system corrupts or you want to install a different operating system (if available), you may follow this instructions.

You may download the OS image from this page. The downloaded image is an img.xz file, and you need to extract it to get the .img file, which can be flashed into Vivid Unit.

Instructions in Windows

In order to flash the OS image into VIvid Unit, you need to put Vivid Unit into MASKROM mode, and your Windows may need extra drivers from Rockchip to recognize your Vivid Unit as a MASKROM device, so it can write data into it via USB.

You can download and run this RK Driver Assistant to help installing the required Rockchip drivers.

You can download and run the RKDevTool to flash the OS image into your Vivid Unit.

Connect your Vivid Unit to your computer via an USB type-C cable. Press and hold the small MASKROM button in the middle of Vivid Unit's circuit board (do not release it) and then press the power button (also do not release it) for about 5 seconds. After releasing both buttons you should see the MASKROM device is detected by RKDevTool. If it doesn't show up, please repeat this step.

Then you can specify the Loader file, which can be downloaded here, or found in the RKDevTool package we provided on this page. The Loader's address should be set to 0x00000000.

You also need to specify the Image file to flash. The Image file is the .img file extracted from the .img.xz file you previously downloaded. The "Storage" of the Image should be set to "EMMC", with address 0x00000000.

Make sure to tick the checkboxes in the Loader and Image lines, as well as the "Write by Address" checkbox, as shown in the figure below. Click the "Run" button to start flashing.

Logging information will be displayed in the right region of the RKDevTool window, and it shows the progress of flashing as well. Once the flashing is done, you may disconnect your Vivid Unit from your computer.

After connecting the power supply to your Vivid Unit, you can tap the power button to boot up the system.
