Cloos i.MX8MM PHG board
=======================
U-Boot for the Cloos i.MX8MM PHG board
Quick Start
-----------
- Get and Build the ARM Trusted firmware
- Get the DDR firmware
- Build U-Boot
- Flash U-Boot into the eMMC
Get and Build the ARM Trusted firmware
--------------------------------------
Note: builddir is U-Boot build directory (source directory for in-tree builds)
Get ATF from: https://github.com/nxp-imx/imx-atf
branch: lf_v2.6
.. 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_phg_defconfig
$ make
Flash U-Boot into the eMMC
--------------------------
Program flash.bin to the eMMC at offset 33KB:
.. code-block:: bash
$ ums 0 mmc 0
$ sudo dd if=flash.bin of=/dev/sd[x] bs=1K seek=33; sync
