phyCORE-i.MX 8M Plus
====================
The phyCORE-i.MX 8M Plus with 2GB of main memory is supported.
Quick Start
-----------
- Build the ARM Trusted firmware binary
- Build the OP-TEE binary (optional)
- Get ddr firmware
- Build U-Boot
- Boot
Build the ARM Trusted firmware binary
-------------------------------------
.. code-block:: bash
$ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
$ cd trusted-firmware-a
$ export CROSS_COMPILE=aarch64-linux-gnu-
$ export IMX_BOOT_UART_BASE=0x30860000
$ # with optee
$ make PLAT=imx8mp SPD=opteed bl31
$ # without optee
$ make PLAT=imx8mp bl31
Build the OP-TEE binary (optional)
----------------------------------
.. code-block:: bash
$ git clone https://github.com/OP-TEE/optee_os.git
$ cd optee_os
$ make CFG_TEE_BENCHMARK=n \
CROSS_COMPILE=aarch64-linux-gnu- \
O=out/arm \
PLATFORM=imx-mx8mp_phyboard_pollux \
CFG_TZDRAM_START=0x56000000
Get the ddr firmware
--------------------
.. code-block:: bash
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.19.bin
$ chmod +x firmware-imx-8.19.bin
$ ./firmware-imx-8.19.bin
Build U-Boot for SD card
------------------------
Copy binaries
^^^^^^^^^^^^^
.. code-block:: bash
$ cp <TF-A dir>/build/imx8mp/release/bl31.bin .
$ cp <OP-TEE dir>/out/arm/core/tee-raw.bin tee.bin
$ cp firmware-imx-8.19/firmware/ddr/synopsys/lpddr4*.bin .
Build U-Boot
^^^^^^^^^^^^
.. code-block:: bash
$ make phycore-imx8mp_defconfig
$ make flash.bin
Flash SD card
^^^^^^^^^^^^^
.. code-block:: bash
$ sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32 conv=sync
