NXP i.MX8QM DMSSE20-a1 board
============================
Quick Start
-----------
- Build the ARM Trusted firmware binary
- Get scfw_tcm.bin and ahab-container.img
- Get imx-mkimage
- Build U-Boot
- Flash the binary into the SD card
- Boot
Get and Build the ARM Trusted Firmware
--------------------------------------
.. code-block:: bash
$ git clone https://github.com/nxp-imx/imx-atf
$ cd imx-atf/
$ git checkout lf-5.10.72-2.2.0 -b lf-5.10.72-2.2.0
$ make PLAT=imx8qm bl31
$ cp build/imx8qm/release/bl31.bin $(builddir)
Get scfw_tcm.bin and ahab-container.img
---------------------------------------
.. code-block:: bash
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-sc-firmware-1.11.0.bin
$ chmod +x imx-sc-firmware-1.11.0.bin
$ ./imx-sc-firmware-1.11.0.bin
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-seco-3.8.5.bin
$ chmod +x imx-seco-3.8.5.bin
$ ./imx-seco-3.8.5.bin
Or use this to avoid running random scripts from the internet,
but note that you must agree to the license the script displays:
.. code-block:: bash
$ dd if=imx-sc-firmware-1.11.0.bin of=imx-sc-firmware-1.11.0.tar.bz2 bs=42757 skip=1
$ tar -xf imx-sc-firmware-1.11.0.tar.bz2
$ cp imx-sc-firmware-1.11.0/mx8qm-val-scfw-tcm.bin $(builddir)
$ dd if=imx-seco-3.8.5.bin of=imx-seco-3.8.5.tar.bz2 bs=43978 skip=1
$ tar -xf imx-seco-3.8.5.tar.bz2
$ cp imx-seco-3.8.5/firmware/seco/mx8qmb0-ahab-container.img $(builddir)
Build U-Boot
------------
.. code-block:: bash
$ export ATF_LOAD_ADDR=0x80000000
$ export BL33_LOAD_ADDR=0x80020000
$ make imx8qm_dmsse20a1_defconfig
$ make
