Verdin iMX8M Plus Module
|
||
|
|
========================
|
||
|
|
|
||
|
|
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 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 IMX_BOOT_UART_BASE=0x30880000 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-8.10.1.bin
|
||
|
|
$ chmod +x firmware-imx-8.10.1.bin
|
||
|
|
$ ./firmware-imx-8.10.1.bin
|
||
|
|
$ cp firmware-imx-8.10.1/firmware/ddr/synopsys/lpddr4*_202006.bin ./
|
||
|
|
|
||
|
|
Build U-Boot
|
||
|
|
------------
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
$ export CROSS_COMPILE=aarch64-linux-gnu-
|
||
|
|
$ make verdin-imx8mp_defconfig
|
||
|
|
$ make
|
||
|
|
|
||
|
|
Flash to eMMC
|
||
|
|
-------------
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
> tftpboot ${loadaddr} flash.bin
|
||
|
|
> setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
|
||
|
|
> mmc dev 2 1 && mmc write ${loadaddr} 0x0 ${blkcnt}
|
||
|
|
|
||
|
|
As a convenience, instead of the last two commands one may also use the update
|
||
|
|
U-Boot wrapper:
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
> run update_uboot
|
||
|
|
|
||
|
|
Boot
|
||
|
|
----
|
||
|
|
|
||
|
|
ATF, U-Boot proper and u-boot.dtb images are packed into FIT image,
|
||
|
|
which is loaded and parsed by SPL.
|
||
|
|
|
||
|
|
Boot sequence is:
|
||
|
|
|
||
|
|
* SPL ---> ATF (TF-A) ---> U-Boot proper
|
||
|
|
|
||
|
|
