| |
| - Build the ARM trusted firmware binary |
| - Get the DDR firmware |
| - Build U-Boot |
| - Flash to eMMC |
| - Boot |
| |
| Get and Build the ARM Trusted Firmware (Trusted Firmware A) |
| ----------------------------------------------------------- |
| |
| .. code-block:: bash |
| |
| $ echo "Downloading and building TF-A..." |
| $ git clone -b lts-v2.10 https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git |
| $ cd trusted-firmware-a |
| |
| Then build ATF (TF-A): |
| |
| .. code-block:: bash |
| |
| $ export CROSS_COMPILE=aarch64-linux-gnu- |
| $ make PLAT=imx8mp bl31 |
| $ cp build/imx8mp/release/bl31.bin ../ |
| |
| Get the DDR Firmware |
| -------------------- |
