$ unset LDFLAGS
$ make PLAT=imx91 bl31
$ cp build/imx91/release/bl31.bin $(srctree)

Get the DDR firmware

$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.21.bin
$ chmod +x firmware-imx-8.21.bin
$ ./firmware-imx-8.21.bin
$ cp firmware-imx-8.21/firmware/ddr/synopsys/lpddr4*.bin $(srctree)

Get ahab-container.img

$ wget  https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-ele-imx-1.3.0-17945fc.bin

$ cp firmware-ele-imx-1.3.0-17945fc/mx91a0-ahab-container.img $(srctree)

Build U-Boot

$ export CROSS_COMPILE=aarch64-poky-linux-
$ make imx91_11x11_evk_defconfig or imx91_11x11_evk_inline_ecc_defconfig
$ make

  • Inline ECC is to enable DDR ECC feature with imx91_11x11_evk_inline_ecc_defconfig
