If you already build our BSP with Yocto, you can get the bl31-imx8mp.bin and lpddr4_pmu_train*.bin from the
directory mentioned here: BSP images
Or you can download the files here: https://download.phytec.de/Software/.../imx-boot-tools
Build U-Boot
Get the U-Boot sources:
host$ git clone git: //git.phytec.de/u-boot-imx
To get the correct U-Boot tag you need to take a look at our release notes, which can be found here: release
notes
The tag needed at this release is called v2021.04_2.2.0-phy7
Check out the needed U-Boot tag :
host$ cd ~/u-boot-imx/
host$ git fetch --all --tags
host$ git checkout tags/v2021.04_2.
2.0 -phy7
Technically, you can now build the U-Boot, but practically there are some further steps necessary:
Create your own development branch:
host$ git checkout -b < new -branch>
Copy all binary's (mentioned here) into the U-Boot build directory
Set up a build environment (mentioned here)
Set this environment variable before building the Image:
host$ export ATF_LOAD_ADDR= 0x970000
build flash.bin ( imx-boot ):
host$ make phycore-imx8mp_defconfig
host$ make flash.bin
Warning
Make sure you rename the files you need so that they are compatible with the mkimage tool .

Note
You can name your development branch as you like, this is just an example.
