i.MX8M Plus NavQ+ Board
|
|
=======================
|
|
|
|
U-Boot for the EmCraft Systems i.MX8M Plus NavQ+ board
|
|
|
|
Quick Start
|
|
-----------
|
|
|
|
- Build the ARM trusted firmware binary
|
|
- Get the DDR firmware
|
|
- Build U-Boot
|
|
- Flash to eMMC
|
|
- Boot
|
|
|
|
Get and Build the ARM Trusted Firmware (Trusted Firmware A)
|
|
-----------------------------------------------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ echo "Downloading and building TF-A..."
|
|
$ git clone -b lts-v2.10 https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
|
|
$ cd trusted-firmware-a
|
|
|
|
Then build ATF (TF-A):
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-linux-gnu-
|
|
$ make PLAT=imx8mp bl31
|
|
$ cp build/imx8mp/release/bl31.bin ../
|
|
|
|
Get the DDR Firmware
|
|
--------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ cd ..
|
|
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.23.bin
|
|
$ chmod +x firmware-imx-8.23.bin
|
|
$ ./firmware-imx-8.23.bin
|
|
$ cp firmware-imx-8.23/firmware/ddr/synopsys/lpddr4*_202006.bin ./
|
|
|
|
Build U-Boot
|
|
------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ export CROSS_COMPILE=aarch64-linux-gnu-
|
|
$ make imx8mp_navqp_defconfig
|
|
$ make
|
|
|
|
Burn the flash.bin to the MicroSD card at offset 32KB:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ sudo dd if=flash.bin of=/dev/sd[x] bs=1K seek=32 conv=notrunc; sync
|
|
|
|
Boot
|
|
----
|
|
|
|
Set Boot switch to SD boot
|
|
Use /dev/ttyUSB0 for U-Boot console
