imx8mp_evk
==========
U-Boot for the NXP i.MX8MP EVK board
Quick Start
-----------
- Build the ARM Trusted firmware binary
- Get the firmware-imx package
- Build U-Boot
- Boot
Get and Build the ARM Trusted firmware
--------------------------------------
Get ATF from: https://github.com/nxp-imx/imx-atf
branch: imx_5.4.70_2.3.0
.. code-block:: bash
$ make PLAT=imx8mp bl31
Get the ddr firmware
--------------------
.. code-block:: bash
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.10.bin
$ chmod +x firmware-imx-8.10.bin
$ ./firmware-imx-8.10.bin
Build U-Boot
------------
.. code-block:: bash
$ export CROSS_COMPILE=aarch64-poky-linux-
$ 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/
$ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_202006.bin ./build/
$ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_202006.bin ./build/
$ cp ../firmware-imx-8.10/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_202006.bin ./build/
$ export ATF_LOAD_ADDR=0x970000
$ make O=build
Burn the flash.bin to the MicroSD card at offset 32KB:
.. code-block:: bash
$sudo dd if=build/flash.bin of=/dev/sd[x] bs=1K seek=32 conv=notrunc; sync
Boot
----
Set Boot switch to SD boot
Use /dev/ttyUSB2 for U-Boot console
