| Note: builddir is U-Boot build directory (source directory for in-tree builds) |
| |
| .. code-block:: bash |
| |
| $ git clone https://github.com/ARM-software/arm-trusted-firmware.git |
| $ git checkout v2.5 |
| $ make PLAT=imx8mq ARCH=aarch64 CROSS_COMPILE=aarch64-linux-gnu- bl31 |
| $ cp build/imx8mq/release/bl31.bin $(builddir) |
| |
| Get DDR and HDMI firmware |
