Overview
4+
********
5+
6+
The IMX943LP5EVK-19 board is a design and evaluation platform based on the
7+
NXP i.MX 943 processor. The i.MX 943 processor integrates up to four Arm
8+
Cortex-A55 cores, along with two Arm Cortex-M33 cores and two Arm Cortex-M7
9+
cores for functional safety. With PLCs, I/O controllers, V2X accelerators,
10+
ML acceleration, energy management, and advanced security, the i.MX 943
11+
processor provides optimized performance and power efficiency for industrial,
12+
IoT, and automotive devices. The i.MX943 device on the board comes in a
13+
compact 19 x 19 mm package.
14+
15+

Supported Features
46+
==================
47+
48+
.. zephyr:board-supported-hw::
49+
50+
System Clock
51+
------------
52+
53+
This board configuration uses a system clock frequency of 24 MHz for Cortex-A55.
54+
Cortex-A55 Core runs up to 1.7 GHz.
55+
56+
Serial Port
57+
-----------
58+
59+
This board configuration uses a single serial communication channel with the
60+
CPU's UART1 for Cortex-A55.
61+
62+
Programming and Debugging (A55)
63+
*******************************
64+
65+
.. zephyr:board-supported-runners::
66+
67+
Boot Zephyr by Using U-Boot Command
68+
===================================
69+
70+
U-Boot "go" command can be used to start Zephyr on A55 Core0.
71+
72+
Dependency
73+
----------
74+
75+
Need to disable all watchdog in U-Boot, otherwise, watchdog will reset the board
76+
after Zephyr start up from the same A55 Core.
77+
78+
Step 1: Build Zephyr application
79+
--------------------------------
80+
81+
Here is an example for the :zephyr:code-sample:`hello_world` application.
82+
83+
.. zephyr-app-commands::
84+
:zephyr-app: samples/hello_world
85+
:host-os: unix
86+
:board: imx943_evk/mimx94398/a55
87+
:goals: build
88+
89+
Step 2: Download Zephyr Image into DDR Memory
90+
---------------------------------------------
91+
92+
Firstly need to download Zephyr binary image into DDR memory, it can use tftp:
93+
94+
.. code-block:: console
95+
96+
tftp 0xd0000000 zephyr.bin
97+
98+
Or copy the Zephyr image ``zephyr.bin`` SD card and plug the card into the board, for example
99+
if copy to the FAT partition of the SD card, use the following U-Boot command to load the image
100+
into DDR memory (assuming the SD card is dev 1, fat partition ID is 1, they could be changed
101+
based on actual setup):
102+
103+
.. code-block:: console
104+
105+
fatload mmc 1:1 0xd0000000 zephyr.bin;
106+
107+
Step 3: Boot Zephyr
108+
-------------------
109+
110+
Use the following command to boot Zephyr on the core0:
111+
112+
.. code-block:: console
113+
114+
dcache off; icache flush; go 0xd0000000;
115+
116+
Then the following log could be found on UART1 console:
117+
118+
.. code-block:: console
119+
120+
*** Booting Zephyr OS build v4.1.0-3650-gdb71736adb68 ***
