=======================
U-Boot for the NXP i.MX 8ULP EVK board
Quick Start
-----------
- Get and Build the ARM Trusted firmware
- Get the uPower firmware
- Get the M33 firmware
- Get ahab-container.img
- Build U-Boot
- Boot
Get and Build the ARM Trusted firmware
--------------------------------------
Note: srctree is U-Boot source directory
Get ATF from: https://github.com/nxp-imx/imx-atf/
branch: lf_v2.10
.. code-block:: bash
$ unset LDFLAGS
$ make PLAT=imx8ulp bl31
$ cp build/imx8ulp/release/bl31.bin $(srctree)
Get the uPower firmware
-----------------------
.. code-block:: bash
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-upower-1.3.1.bin
$ chmod +x firmware-upower-1.3.1.bin
$ ./firmware-upower-1.3.1.bin
$ cp firmware-upower-1.3.1/upower_a1.bin $(srctree)/upower.bin
Get the M33 firmware
--------------------
.. code-block:: bash
$ wget http://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx8ulp-m33-demo-2.14.1.bin
$ chmod +x imx8ulp-m33-demo-2.14.1.bin
$ ./imx8ulp-m33-demo-2.14.1.bin
$ cp imx8ulp-m33-demo-2.14.1/imx8ulp_m33_TCM_power_mode_switch.bin $(srctree)/m33_image.bin
Get ahab-container.img
---------------------------------------
.. code-block:: bash
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-ele-imx-0.1.2-4ed450a.bin
$ chmod +x firmware-ele-imx-0.1.2-4ed450a.bin
$ ./firmware-ele-imx-0.1.2-4ed450a.bin
$ cp firmware-ele-imx-0.1.2-4ed450a/mx8ulpa2-ahab-container.img $(srctree)
Build U-Boot
------------
.. code-block:: bash
$ export CROSS_COMPILE=aarch64-poky-linux-
$ make imx8ulp_evk_defconfig
$ make
Burn the flash.bin to MicroSD card offset 32KB:
.. code-block:: bash
$ dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32 conv=notrunc
Boot
----
Set Boot switch to SD boot
