host:~/u-boot-imx$ make <defconfig>
host:~/u-boot-imx$ make
host:~/u-boot-imx$ cd ..
Note
In command above replace <defconfig> with imx93-phyboard-segin_defconfig or
imx93-phyboard-nash_defconfig, depending on the board you are about to build for.
Build nal ash.bin with imx-mkimage
• Get imx-mkimage:
host:~$ git clone https://github.com/nxp-imx/imx-mkimage
host:~$ cd imx-mkimage/
host:~/imx-mkimage$ git checkout tags/lf-6.1.55-2.2.0
• Copy rmware binaries into imx-mkimage
host:~/imx-mkimage$ cp ../artefacts/bl31-imx93.bin ./iMX9/bl31.bin
host:~/imx-mkimage$ cp \
../artefacts/lpddr4_* \
../artefacts/mx93a1-ahab-container.img \
../artefacts/tee.bin \
./iMX9/
• Copy u-boot binaries and DTB into imx-mkimage
host:~/imx-mkimage$ cp ../u-boot-imx/spl/u-boot-spl.bin ../u-boot-imx/u-boot.bin ./iMX9/
host:~/imx-mkimage$ cp ../u-boot-imx/arch/arm/dts/<dtb> ./iMX9/
