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.MX8MM EVK board
|
|
|
|
Quick Start
|
|
-----------
|
|
|
|
- Build the ARM Trusted firmware binary
|
|
- Get ddr firmware
|
|
- Build U-Boot
|
|
- Boot
|
|
|
|
Get and Build the ARM Trusted firmware
|
|
--------------------------------------
|
|
|
|
Note: builddir is U-Boot build directory (source directory for in-tree builds)
|
|
Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
|
|
branch: imx_5.4.47_2.2.0
|
|
|
|
.. code-block:: bash
|
|
|
|
$ make PLAT=imx8mm bl31
|
|
$ cp build/imx8mm/release/bl31.bin $(builddir)
|
|
|
|
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
|
|
$ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin $(builddir)
|
|
|
|
Build U-Boot
|
|
------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-poky-linux-
|
|
$ make imx8mm_evk_defconfig
|
|
$ export ATF_LOAD_ADDR=0x920000
|
|
$ make flash.bin
|
|
|
|
Burn the flash.bin to MicroSD card offset 33KB:
|
|
|
|
.. code-block:: bash
|
|
|
|
$sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=33 conv=notrunc
