Update branch and version information of ATF and DDR firmware files to point to latest releases provided by NXP. This is especially critical for imx8mp evk, as the ATF support for that SoC is only available in latest releases. Align all SoCs from imx8m family to use identical revisions of ATF and DDR firmware.

==========
|
|
|
|
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
|
|
--------------------------------------
|
|
|
|
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
|
|
|
|
.. 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
|
|
|
|
Build U-Boot
|
|
------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-poky-linux-
|
|
$ make imx8mp_evk_defconfig
|
|
$ export ATF_LOAD_ADDR=0x960000
|
|
$ make 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
|
|
|
|
Boot
|
|
----
|
|
|
|
Set Boot switch to SD boot
|
|
Use /dev/ttyUSB2 for U-Boot console
