NXP i.MX 9 Series
|
|
==================
|
|
|
|
Building on the market-proven i.MX 6 and i.MX 8 series, i.MX 9 series applications
|
|
processors bring together higher performance applications cores, an independent
|
|
MCU-like real-time domain, Energy Flex architecture, state-of-the-art security
|
|
with EdgeLock® secure enclave and dedicated multi-sensory data processing engines
|
|
(graphics, image, display, audio and voice). The i.MX 9 series, part of the EdgeVerse™
|
|
edge computing platform, integrates hardware neural processing units across many
|
|
members of the series for acceleration of machine learning applications at the edge
|
|
`i.MX9 Applications Processors`_.

Boot Sequence
|
|
-------------
|
|
|
|
BootROM --> SPL --> BL31 --> BL33(u-boot) --> Linux kernel

|
|
|
How to build
|
|
------------
|
|
|
|
Build Procedure
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- Prepare AARCH64 toolchain.
|
|
|
|
- Get the ELE FW image from NXP linux SDK package
|
|
|
|
- Build SPL and u-boot firstly, and get binary images: u-boot-spl.bin,
|
|
u-boot.bin and dtb
|
|
|
|
- Build TF-A
|
|
|
|
Build bl31:
|
|
|
|
.. code:: shell
|
|
|
|
CROSS_COMPILE=aarch64-linux-gnu- make PLAT=<Target_SoC> bl31
|
|
|
|
Target_SoC should be "imx93" for i.MX93 SoC.
|
|
|
|
Deploy TF-A Images
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
TF-A binary(bl31.bin), u-boot-spl.bin u-boot.bin, ELE FW image are combined
|
|
together to generate a binary file called flash.bin, the imx-mkimage tool is
|
|
used to generate flash.bin, and flash.bin needs to be flashed into SD card
|
|
with certain offset for BOOT ROM.
