Description
|
||
|
|
===========
|
||
|
|
|
||
|
|
The QorIQ® LS1043A processor is NXP's first quad-core, 64-bit Arm®-based
|
||
|
|
processor for embedded networking. The LS1023A (two core version) and the
|
||
|
|
LS1043A (four core version) deliver greater than 10 Gbps of performance
|
||
|
|
in a flexible I/O package supporting fanless designs. This SoC is a
|
||
|
|
purpose-built solution for small-form-factor networking and industrial
|
||
|
|
applications with BOM optimizations for economic low layer PCB, lower cost
|
||
|
|
power supply and single clock design. The new 0.9V versions of the LS1043A
|
||
|
|
and LS1023A deliver addition power savings for applications such as Wireless
|
||
|
|
LAN and to Power over Ethernet systems.

How to build
|
||
|
|
============
|
||
|
|
|
||
|
|
Build Procedure
|
||
|
|
---------------
|
||
|
|
|
||
|
|
- Prepare AARCH64 toolchain.
|
||
|
|
|
||
|
|
- Build u-boot and OPTee firstly, and get binary images: u-boot.bin and tee.bin
|
||
|
|
|
||
|
|
- Build TF-A for Nor boot
|
||
|
|
|
||
|
|
Build bl1:
|
||
|
|
|
||
|
|
.. code:: shell
|
||
|
|
|
||
|
|
CROSS_COMPILE=aarch64-linux-gnu- make PLAT=ls1043 bl1
|
||
|
|
|
||
|
|
Build fip:
|
||
|
|
|
||
|
|
.. code:: shell
|
||
|
|
|
||
|
|
CROSS_COMPILE=aarch64-linux-gnu- make PLAT=ls1043 fip \
|
||
|
|
BL33=u-boot.bin NEED_BL32=yes BL32=tee.bin SPD=opteed
|
||
|
|
|
||
|
|
Deploy TF-A Images
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
- Deploy TF-A images on Nor flash Alt Bank.
|
||
|
|
|
||
|
|
.. code:: shell
|
||
|
|
|
||
|
|
=> tftp 82000000 bl1.bin
|
||
|
|
=> pro off all;era 64100000 +$filesize;cp.b 82000000 64100000 $filesize
|
||
|
|
|
||
|
|
=> tftp 82000000 fip.bin
|
||
|
|
=> pro off all;era 64120000 +$filesize;cp.b 82000000 64120000 $filesize
|
||
|
|
|
||
|
|
Then change to Alt bank and boot up TF-A:
|
||
|
|
|
||
|
|
.. code:: shell
|
||
|
|
|
||
|
|
=> cpld reset altbank
|
||
|
|
|
||
|
|
|
||
|
