| Get and Build the ARM Trusted firmware |
| -------------------------------------- |
| |
| Note: srctree is U-Boot source directory |
| Get ATF from: https://github.com/nxp-imx/imx-atf/ |
| branch: lf_v2.10 |
| |
| .. code-block:: bash |
| |
| $ unset LDFLAGS |
| $ make PLAT=imx91 bl31 |
| $ cp build/imx91/release/bl31.bin $(srctree) |
| |
| Get the DDR firmware |
| -------------------- |
| |
| .. code-block:: bash |
| |
| $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.21.bin |
