Get and Build the ARM Trusted firmware
--------------------------------------
-Note: $(srctree) is the U-Boot source directory
Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
-branch: imx_5.4.47_2.2.0
+branch: imx_5.4.70_2.3.0
.. code-block:: bash
$ make PLAT=imx8mp bl31
- $ cp build/imx8mp/release/bl31.bin $(srctree)
Get the ddr firmware
--------------------
.. code-block:: bash
- $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin
- $ chmod +x firmware-imx-8.9.bin
- $ ./firmware-imx-8.9.bin
- $ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_1d_dmem.bin
- $ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_201904.bin $(srctree)/lpddr4_pmu_train_1d_imem.bin
- $ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_2d_dmem.bin
- $ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_201904.bin $(srctree)/lpddr4_pmu_train_2d_imem.bin
+ $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.10.bin
+ $ chmod +x firmware-imx-8.10.bin

Build U-Boot
------------
.. code-block:: bash
$ export CROSS_COMPILE=aarch64-poky-linux-
- $ make imx8mp_evk_defconfig
- $ export ATF_LOAD_ADDR=0x960000
- $ make flash.bin
+ $ make O=build imx8mp_evk_defconfig
+ $ cp ../imx-atf/build/imx8mp/release/bl31.bin ./build/bl31.bin
+ $ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_202006.bin ./build/lpddr4_pmu_train_1d_dmem.bin
+ $ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_202006.bin ./build/lpddr4_pmu_train_1d_imem.bin

+ $ export ATF_LOAD_ADDR=0x970000
+ $ make O=build flash.bin
Burn the flash.bin to the MicroSD card at offset 32KB:
.. code-block:: bash
- $sudo dd if=flash.bin of=/dev/sd[x] bs=1K seek=32 conv=notrunc; sync
+ $sudo dd if=build/flash.bin of=/dev/sd[x] bs=1K seek=32 conv=notrunc; sync
