Fix the Verdin module output which was missing white space for correct rendering. While at it also leave product links, add section author also for the Verdin iMX8M Mini and Plus, and add a missing CROSS_COMPILE export for the Verdin iMX8M Mini.

|
|
========================
|
|
|
|
- SoM: https://www.toradex.com/computer-on-modules/verdin-arm-family/nxp-imx-8m-plus
|
|
- Carrier board: https://www.toradex.com/products/carrier-board/verdin-development-board-kit
|
|
|
|
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
|
|
|
|
Output:
|
|
|
|
.. code-block:: none
