imx93_var_som
=======================
U-Boot for the Variscite VAR-SOM-MX93 Symphony evaluation board
Quick Start
-----------
- Get and Build the ARM Trusted firmware
- Get the DDR firmware
- Get ahab-container.img
- Build U-Boot
- Boot
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_v2.8
.. code-block:: bash
$ unset LDFLAGS
$ make PLAT=imx93 bl31
$ cp build/imx93/release/bl31.bin $(srctree)
Get the DDR firmware
--------------------
.. code-block:: bash
$ 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
---------------------------------------
.. code-block:: bash
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-sentinel-0.10.bin
$ chmod +x firmware-sentinel-0.10.bin
$ ./firmware-sentinel-0.10.bin
$ cp firmware-sentinel-0.10/mx93a0-ahab-container.img $(srctree)
Build U-Boot
------------
.. code-block:: bash
$ export CROSS_COMPILE=aarch64-poky-linux-
$ make imx93_var_som_defconfig
$ make
Burn the flash.bin to MicroSD card offset 32KB:
.. code-block:: bash
$ dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32 conv=notrunc
Boot
