System Clock

SensorTile.box PRO System Clock could be driven by internal or external oscillator, as well as main PLL clock. By default, the System clock is driven by the PLL clock at 80MHz, driven by the 16MHz external oscillator. The system clock can be boosted to 120MHz. The internal AHB/APB1/APB2 AMBA buses are all clocked at 80MHz.

Serial Port

The SensorTile.box PRO has 4 U(S)ARTs. The UART4 is connected to JTAG/SWD connector and may be used as console.

USB interface

SensorTile.box PRO can be connected as a USB device to a PC host through its USB-C connector. The final application may use it to declare SensorTile.box PRO device as belonging to a certain standard or vendor class, e.g. a CDC, a mass storage or a composite device with both functions.

BlueNRG-LP chip

The board is equipped with an STMicroelectronics BlueNRG-LP [12] chip. Before running Zephyr Bluetooth samples on SensorTile.box PRO, it is required to upgrade the BlueNRG chip with a Zephyr BLE stack compatible firmware. The upgrade may be easily performed using the application provided in SensorTile.box PRO BLE firmware upgrade package [13]. For more information about BLE binaries for SensorTile.box family, see stsw-mkbox-bleco [14].

Console

There are two possible options for Zephyr console output:

• through common CDC ACM UART backend configuration for all boards

• through UART4 which is available on SWD connector (JP2). In this case a JTAG adapter can be used to connect SensorTile.box PRO and have both SWD and console lines available.

  To enable console and shell over UART:

  • in your prj.conf, override the board’s default configuration by setting CONFIG_BOARD_SERIAL_BACKEND_CDC_ACM=n

  • add an overlay file named <board>.overlay:

/ {
    chosen {
       zephyr,console = &uart4;
       zephyr,shell-uart = &uart4;
     };
  };

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 BOOT0 button pressed. No additional hardware is required except a USB-C cable. This method is fully supported by Flash & Debug Host Tools. You can read more about how to enable and use the ROM bootloader by checking the application note AN2606 [15] (STM32U585xx section).

2. Using SWD hardware tools

   This method requires to connect additional hardware, like a ST-LINK/V3 embedded debug tool, to the board SWD connector.

DFU flashing

Install dfu-util

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 [16]

Flash an Application to SensorTile.box PRO

While pressing the BOOT0 button, connect the USB-C cable to the USB OTG SensorTile.box PRO port and to your computer. The board should be forced to enter DFU mode.

Check that the board is indeed in DFU mode:

$ sudo dfu-util -l
dfu-util 0.9
