+Quick Start +-----------
+- Get ahab-container.img +- Get the DDR PHY Firmware Images +- Get and Build OEI Images +- Get and Build System Manager Image +- Get and Build the ARM Trusted Firmware +- Build the Bootloader Image +- Boot
+Get ahab-container.img +--------------------------------------
+Note: srctree is U-Boot source directory
+.. code-block:: bash
- $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-ele-imx-1.3.0-17945fc.bin
- $ chmod +x firmware-ele-imx-1.3.0-17945fc.bin

- $ cp firmware-ele-imx-1.3.0-17945fc.bin/mx95a0-ahab-container.img $(srctree)
Hi Alice,
typo here in the path. Should be: cp firmware-ele-imx-1.3.0-17945fc/mx95a0-ahab-container.img $(srctree)
+Get the DDR PHY Firmware Images +--------------------------------------
+Note: srctree is U-Boot source directory
+.. code-block:: bash
- $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.26-d4c33ab.bin
- $ chmod +x firmware-imx-8.26-d4c33ab.bin
- $ ./firmware-imx-8.26-d4c33ab.bin
- $ cp firmware-imx-8.26-d4c33ab/firmware/ddr/synopsys/lpddr5*v202311.bin $(srctree)
+Get and Build OEI Images +--------------------------------------
+Note: srctree is U-Boot source directory +Get OEI from: https://github.com/nxp-imx/imx-oei +branch: master
how about just adding a 'git clone https://github.com/nxp-imx/imx-oei -b master' in your instructions below and update the make/cp to use imx-oei path?
+.. code-block:: bash
- $ sudo apt -y install make gcc g++-multilib srecord
- $ wget https://developer.arm.com/-/media/Files/downloads/gnu/13.3.rel1/binrel/arm-g...
- $ tar xvf arm-gnu-toolchain-13.3.rel1-x86_64-arm-none-eabi.tar.xz
- $ export TOOLS=$PWD
- $ make board=mx95lp5 oei=ddr DEBUG=1

+Get and Build System Manager Image +--------------------------------------
+Note: srctree is U-Boot source directory +Get System Manager from: https://github.com/nxp-imx/imx-sm +branch: master
how about just adding a 'git clone https://github.com/nxp-imx/imx-sm -b master' in your instructions below and update make/cp to use imx-sm path?

+Get and Build the ARM Trusted Firmware +--------------------------------------
+Note: srctree is U-Boot source directory +Get ATF from: https://github.com/nxp-imx/imx-atf/ +branch: lf_v2.10
how about just adding a 'git clone https://github.com/nxp-imx/imx-atf -b lf_v2.10' in your instructions below and update make/cp to use imx-atf path?
+.. code-block:: bash
- $ unset LDFLAGS
why? where was LDFLAGS set?
- $ make PLAT=imx95 bl31
You need to export CROSS_COMPILE before building here
- $ cp build/imx95/release/bl31.bin $(srctree)
+Build the Bootloader Image +------------
+.. code-block:: bash
- $ export CROSS_COMPILE=aarch64-poky-linux-
- $ make imx95_19x19_evk_defconfig
- $ make
+Copy imx-boot-imx95.bin to the MicroSD card:
+.. code-block:: bash
- $ sudo dd if=imx-boot-imx95.bin of=/dev/sdb bs=1k seek=32 conv=fsync
+Boot +----
+Set i.MX95 boot device to MicroSD card
I gave this series a go on top of 5cfbf8c364 origin/next on an EVK I have here and I saw no u-boot proper output after the ATF.
Here is what I saw on UART2: U-Boot SPL 2025.01-rc5-00393-g9b292f7d347f (Dec 27 2024 - 16:12:20 -0800) DDRMIX is powered UP Normal Boot Trying to boot from MMC2 Primary set selected Load image from MMC/SD 0xdec00 NOTICE: BL31: v2.10.0 (release):lf-6.6.52-2.2.0 NOTICE: BL31: Built : 16:06:15, Dec 27 2024

Any thoughts on what is wrong here?
