This toolchain provides multiple cross compilers and are publicly available on www.developer.arm.com We thoroughly test TF-A in CI using: AArch32 bare-metal target (arm-none-eabi) AArch64 ELF bare-metal target (aarch64-none-elf) Change-Id: I2360a3ac6705c68dca781b85e9894867df255b3e Signed-off-by: Madhukar Pappireddy <madhukar.pappireddy@arm.com>

NXP i.MX 8M Series
|
|
==================
|
|
|
|
The i.MX 8M family of applications processors based on Arm Corte-A53 and Cortex-M4
|
|
cores provide high-performance computing, power efficiency, enhanced system
|
|
reliability and embedded security needed to drive the growth of fast-growing
|
|
edge node computing, streaming multimedia, and machine learning applications.

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

How to build
|
|
------------
|
|
|
|
Build Procedure
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- Prepare AARCH64 toolchain.
|
|
|
|
- Build spl and u-boot firstly, and get binary images: u-boot-spl.bin,
|
|
u-boot-nodtb.bin and dtb for the target board.
|
|
|
|
- Build TF-A
|
|
|
|
Build bl31:
|
|
|
|
.. code:: shell
|
|
|
|
CROSS_COMPILE=aarch64-none-elf- make PLAT=<Target_SoC> bl31
|
|
|
|
Target_SoC should be "imx8mq" for i.MX8MQ SoC.
|
|
Target_SoC should be "imx8mm" for i.MX8MM SoC.
|
|
|
|
Deploy TF-A Images
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
TF-A binary(bl31.bin), u-boot-spl.bin u-boot-nodtb.bin and dtb 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. the u-boot and imx-mkimage will be upstreamed
|
|
soon, this doc will be updated once they are ready, and the link will be posted.
