Setup environment

Suggested current toolchains are ARM 14.3 (https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads):

$ export TOOLS=<path/to/directory/with/toolchains>
$ export CROSS_COMPILE_32=<path/to/arm/toolchain/bin/>arm-none-linux-gnueabihf-
$ export CROSS_COMPILE_64=<path/to/arm64/toolchain/bin/>aarch64-none-linux-gnu-

Get ahab-container.img

Note: $srctree is the U-Boot source directory

$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-ele-imx-2.0.2-89161a8.bin
$ sh firmware-ele-imx-2.0.2-89161a8.bin --auto-accept
$ cp firmware-ele-imx-2.0.2-89161a8/mx95b0-ahab-container.img $(srctree)

Get DDR PHY Firmware Images

Note: $srctree is the U-Boot source directory

$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.28-994fa14.bin
$ sh firmware-imx-8.28-994fa14.bin --auto-accept
$ cp firmware-imx-8.28-994fa14/firmware/ddr/synopsys/lpddr5*v202409.bin $(srctree)

Get and Build OEI Images

Note: $srctree is the U-Boot source directory Get OEI from: https://git.toradex.com/cgit/imx-oei-toradex.git/ branch: main

$ git clone -b main https://git.toradex.com/cgit/imx-oei-toradex.git/
$ cd imx-oei-toradex

$ make board=toradex-smarc-imx95 oei=ddr DEBUG=1 r=B0 all
$ cp build/toradex-smarc-imx95/ddr/oei-m33-ddr.bin $(srctree)

$ make board=toradex-smarc-imx95 oei=tcm DEBUG=1 r=B0 all
$ cp build/toradex-smarc-imx95/tcm/oei-m33-tcm.bin $(srctree)

The Makefile will set DDR_CONFIG automatically based on the selected silicon revision.

Get and Build the System Manager Image

Note: $srctree is the U-Boot source directory Get System Manager from: https://git.toradex.com/cgit/imx-sm-toradex.git/ branch: main

$ git clone -b main https://git.toradex.com/cgit/imx-sm-toradex.git/
$ cd imx-sm-toradex
$ make config=tdx-smarc-imx95 all
$ cp build/tdx-smarc-imx95/m33_image.bin $(srctree)

Get and Build the ARM Trusted Firmware

Note: $srctree is the U-Boot source directory Get ATF from: https://github.com/nxp-imx/imx-atf/ branch: lf_v2.12

$ export CROSS_COMPILE=$CROSS_COMPILE_64
$ unset LDFLAGS
$ unset AS
$ git clone -b lf_v2.12 https://github.com/nxp-imx/imx-atf.git
$ cd imx-atf
$ make PLAT=imx95 bl31
$ cp build/imx95/release/bl31.bin $(srctree)

Build the Bootloader Image

$ export CROSS_COMPILE=$CROSS_COMPILE_64
$ make toradex-smarc-imx95_defconfig
$ make

Flash to eMMC

> tftpboot ${loadaddr} flash.bin
> setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
> mmc dev 0 1 && mmc write ${loadaddr} 0x0 ${blkcnt}

As a convenience, instead of the last two commands, one may also use the update U-Boot wrapper:

> run update_uboot

Boot

Boot sequence is:

  • SPL —> ATF (TF-A) —> U-Boot proper
