``boards/arm/b_u585i_iot02a/b_u585i_iot02a_defconfig``
|
||||
|
||||
|
||||
Connections and IOs
|
||||
===================
|
||||
|
||||
B_U585I_IOT02A Discovery kit has 9 GPIO controllers (from A to I). These controllers are responsible for pin muxing,
|
||||
input/output, pull-up, etc.
|
||||
|
||||
For mode details please refer to `B U585I IOT02A board User Manual`_.
|
||||
|
||||
Default Zephyr Peripheral Mapping:
|
||||
----------------------------------
|
||||
|
||||
- UART_1 TX/RX : PA9/PA10 (ST-Link Virtual Port Com)
|
||||
- LD1 : PH7
|
||||
- LD2 : PH6
|
||||
- user button : PC13
|
||||
|
||||
System Clock
|
||||
------------
|
||||
|
||||
B_U585I_IOT02A Discovery System Clock could be driven by an internal or external oscillator,
|
||||
as well as the main PLL clock. By default the System clock is driven by the PLL clock at 80MHz,
|
||||
driven by 16MHz high speed internal oscillator.
|
||||
|
||||
Serial Port
|
||||
-----------
|
||||
|
||||
B_U585I_IOT02A Discovery kit has 4 U(S)ARTs. The Zephyr console output is assigned to UART1.
|
||||
Default settings are 115200 8N1.

========
|

|
||||
B_U585I_IOT02A Discovery kit includes an ST-LINK/V2-1 embedded debug tool interface.
|
||||
This interface is supported by the openocd version included in Zephyr SDK.
|
||||
|
||||
Flashing an application to B_U585I_IOT02A Discovery kit
|
||||
-------------------------------------------------------
|
||||
|
||||
Connect the B_U585I_IOT02A Discovery kit to your host computer using the USB
|
||||
port, then run a serial host program to connect with your Discovery
|
||||
board. For example:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ minicom -D /dev/ttyACM0
|
||||
|
||||
Then, build and flash in the usual way. Here is an example for the
|
||||
:ref:`hello_world` application.
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/hello_world
|
||||
:board: b_u585i_iot02a
|
||||
:goals: build flash
|
||||
|
||||
You should see the following message on the console:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
Hello World! arm
|
||||

Debugging

=========
|
||||
|
||||
STM32U5 support is not currently supported in openocd. As a temporary workaround,
|
||||
user can use `STMicroelectronics customized version of OpenOCD`_ to debug the
|
||||
the B_U585I_IOT02A Discovery kit.
|
||||
For this you need to fetch this repo and build openocd following the instructions
|
||||
provided in the README of the project. Then, build zephyr project indicating the
|
||||
openocd location in west build command.
|
||||
|
||||
Here is an example for the :ref:`blinky-sample` application.
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/basic/blinky
|
||||
:board: b_u585i_iot02a
|
||||
:gen-args: -DOPENOCD="<path_to_openocd>/openocd/src/openocd" -DOPENOCD_DEFAULT_PATH="<path_to_openocd>/openocd/tcl/"
|
||||
:goals: build
|
||||
|
||||
Then, indicate openocd as the chosen runner in flash and debug commands:
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/basic/blinky
|
||||
:board: b_u585i_iot02a
|
||||
:gen-args: -r openocd
|
||||
:goals: flash
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/basic/blinky
|
||||
:board: nucleo_u575zi_q
|
||||
:gen-args: -r openocd
|
||||
:goals: debug
