System Clock
------------
STEVAL-STWINBX1 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 160MHz,
driven by 16MHz high speed external oscillator.
The internal AHB/APB1/APB2/APB3 AMBA buses are all clocked at 160MHz.
Serial Port
-----------
The USART2 is connected to JTAG/SWD connector
and may be used as console.
USB interface
-------------
STEVAL-STWINBX1 can be connected as a USB device to a PC host through its USB-C connector.
The final application may use it to declare STEVAL-STWINBX1 device as belonging to a
certain standard or vendor class, e.g. a CDC, a mass storage or a composite device with both
functions.
Console
-------
There are two possible options for Zephyr console output:
- through USART2 which is available on SWD connector (CN4). In this case a JTAG adapter
can be used to connect STEVAL-STWINBX1 and have both SWD and console lines available.
To enable console and shell over UART
- switch the console lines from cdc_acm to uart4
(:file:`boards/st/steval_stwinbx1/steval_stwinbx1.dts`)
- comment out the USB configuration macros
(:file:`boards/st/steval_stwinbx1/steval_stwinbx1_defconfig`)
.. code-block:: dts
:caption: boards/st/steval_stwinbx1/steval_stwinbx1.dts
/ {
chosen {
zephyr,console = &usart2;
zephyr,shell-uart = &usart2;
//zephyr,console = &cdc_acm_uart0;
//zephyr,shell-uart = &cdc_acm_uart0;
};
};
.. code-block:: Kconfig
:caption: boards/st/steval_stwinbx1/steval_stwinbx1_defconfig
# Comment out following USB config lines when
# switching console to UART
#CONFIG_USB_DEVICE_STACK=y
#CONFIG_USB_DEVICE_VID=0x0483
#CONFIG_USB_DEVICE_PID=0x5740
#CONFIG_USB_DEVICE_PRODUCT="Zephyr CDC STEval-STWinbx1"
#CONFIG_USB_DEVICE_INITIALIZE_AT_BOOT=n
- through USB as USB CDC/ACM class. This is the default case present in the board dts file.
.. code-block:: dts
:caption: boards/st/steval_stwinbx1/steval_stwinbx1.dts
/ {
chosen {
zephyr,console = &cdc_acm_uart0;
};
};
&zephyr_udc0 {
cdc_acm_uart0: cdc_acm_uart0 {
compatible = "zephyr,cdc-acm-uart";
};
};
Console default settings are 115200 8N1.
Programming and Debugging
-------------------------
There are two alternative methods of flashing ST Sensortile.box Pro board:
1. Using DFU software tools
This method requires to enter STM32U585 ROM bootloader DFU mode
by powering up (or reset) the board while keeping the USER (BOOT0) button pressed.
No additional hardware is required except a USB-C cable. This method is fully
supported by :ref:`flash-debug-host-tools`.
You can read more about how to enable and use the ROM bootloader by checking
the application note `AN2606`_ (STM32U585xx section).
2. Using SWD hardware tools
The STEVAL-STWINBX1 does not include a on-board debug probe.
It requires to connect additional hardware, like a ST-LINK/V3
embedded debug tool, to the board STDC14 connector (CN4) labeled ``MCU-/SWD``.
Install dfu-util
----------------
.. note::
Required only to use dfu-util runner.
It is recommended to use at least v0.9 of dfu-util. The package available in
Debian and Ubuntu can be quite old, so you might have to build dfu-util from source.
Information about how to get the source code and how to build it can be found
at the `DFU-UTIL website`_
Install STM32CubeProgrammer
---------------------------
.. note::
Required to program over DFU (default) or SWD.
It is recommended to use the latest version of `STM32CubeProgrammer`_
Flash an Application to STEVAL-STWINBX1
------------------------------------------
There are two ways to enter DFU mode:
1. USB-C cable not connected
While pressing the USER button, connect the USB-C cable to the USB OTG STEVAL-STWINBX1
port and to your computer.
2. USB-C cable connected
While pressing the USER button, press the RESET button and release it.
With both methods, the board should be forced to enter DFU mode.
Check that the board is indeed in DFU mode:
.. code-block:: console
$ sudo dfu-util -l
dfu-util 0.9
