The instructions here will tell how to run OP-TEE on ROCK Pi 4 / ROCK 4 boards.

Supported ROCK Pi 4 boards

There are several versions of the ROCK Pi 4 board, each with 1GB, 2GB or 4GB RAM options. OP-TEE has been tested and is known to work with a Rock Pi 4 Model B OP1 4GB. Other variants will likely work too.


The console can be accessed using a USB adapter connected to the board as described in the serial console documentation.

Build instructions

Just follow the “Get and build the solution” as described in build. To flash the board you will need a USB type A to type A cable. The make flash step will tell you how to connect the cable and use the buttons.
