Verdin iMX8M Mini 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..."
|
2020-03-05 20:56:26 +00:00
|
|
|
$ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
|
|
|
|
|
$ cd trusted-firmware-a
|
2020-02-12 15:14:29 +00:00
|
|
|
|
|
|
|
|
Then build ATF (TF-A):
|
|
|
|
|
|
|
|
|
|
.. code-block:: bash
|
|
|
|
|
|
2020-03-05 20:56:26 +00:00
|
|
|
$ make PLAT=imx8mm IMX_BOOT_UART_BASE=0x30860000 bl31
|
|
|
|
|
$ cp build/imx8mm/release/bl31.bin ../
|
2020-02-12 15:14:29 +00:00
|
|
|
|
|
|
|
|
Get the DDR Firmware
|
|
|
|
|
--------------------
|
|
|
|
|
|
|
|
|
|
.. code-block:: bash
|
|
|
|
|

2021-10-09 20:41:07 +00:00
|
|
|
$ 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*.bin ./
|

|
|
|
|
|
|
|
|
Build U-Boot
|
|
|
|
|
------------
|
|
|
|
|
.. code-block:: bash
|
|
|
|
|
|
|
|
|
|
$ export CROSS_COMPILE=aarch64-linux-gnu-
|
2020-03-05 20:56:26 +00:00
|
|
|
$ export ATF_LOAD_ADDR=0x920000
|
2020-02-12 15:14:29 +00:00
|
|
|
$ make verdin-imx8mm_defconfig
|
2021-10-09 20:41:07 +00:00
|
|
|
$ make
|
2020-02-12 15:14:29 +00:00
|
|
|
|
|
|
|
|
Flash to eMMC
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
.. code-block:: bash
|
|
|
|
|
|
|
|
|
|
> tftpboot ${loadaddr} flash.bin
|
|
|
|
|
> setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
|
|
|
|
|
> mmc dev 0 1 && mmc write ${loadaddr} 0x2 ${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
|
|
|
|
|
|
