Zephyr board options
The STM32L562e is an SoC with Cortex-M33 architecture. Zephyr provides support for building for both Secure and Non-Secure firmware.
The BOARD options are summarized below:
BOARD |
Description |
|---|---|
stm32l562e_dk |
For building Trust Zone Disabled firmware |
stm32l562e_dk/stm32l562xx/ns |
For building Non-Secure firmware |
Here are the instructions to build Zephyr with a non-secure configuration, using TF-M IPC sample:
$ west build -b stm32l562e_dk/stm32l562xx/ns samples/tfm_integration/tfm_ipc/
Once done, before flashing, you need to first run a generated script that will set platform option bytes config and erase platform (among others, option bit TZEN will be set).
$ ./build/tfm/api_ns/regression.sh $ west flash
Please note that, after having run a TFM sample on the board, you will need to
run ./build/tfm/api_ns/regression.sh once more to clean up the board from secure
options and get back the platform back to a “normal” state and be able to run
usual, non-TFM, binaries.
Also note that, even then, TZEN will remain set, and you will need to use
STM32CubeProgrammer to disable it fully, if required.
Connections and IOs
STM32L562E-DK Discovery Board has 8 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc.
For more details please refer to STM32L562E-DK Discovery board User Manual.
Default Zephyr Peripheral Mapping:
USART_1 TX/RX : PA9/PA10
USART_3 TX/RX : PC10/PC11
I2C_1 SCL/SDA : PB6/PB7
SPI_1 SCK/MISO/MOSI : PG2/PG3/PG4 (BT SPI bus)
SPI_3 NSS/SCK/MISO/MOSI : PE0/PG9/PB4/PB5 (Arduino SPI)
USER_PB : PC13
LD10 : PG12
PWM_2_CH1 : PA0
DAC1 : PA4
ADC1 : PC4
System Clock
STM32L562E-DK System Clock could be driven by internal or external oscillator, as well as main PLL clock. By default System clock is driven by PLL clock at 110MHz, driven by 4MHz medium speed internal oscillator.
Serial Port
STM32L562E-DK Discovery board has 6 U(S)ARTs. The Zephyr console output is assigned to USART1. Default settings are 115200 8N1.
TFT LCD screen and touch panel
The TFT LCD screen and touch panel are supported for the STM32L562E-DK Discovery board. They can be tested using LVGL basic sample sample:
# From the root of the zephyr repository
west build -b stm32l562e_dk samples/subsys/display/lvgl
Programming and Debugging
STM32L562E-DK Discovery board includes an ST-LINK/V3E embedded debug tool interface.
Applications for the stm32l562e_dk board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Flashing
The board is configured to be flashed using west STM32CubeProgrammer runner, so its installation is required.
Alternatively, OpenOCD can also be used to flash the board using
the --runner (or -r) option:
$ west flash --runner openocd
Support can also be enabled for pyOCD by adding “pack” support with the following pyOCD commands:
$ pyocd pack --update
$ pyocd pack --install stm32l562qe
Flashing an application to STM32L562E-DK Discovery
Connect the STM32L562E-DK Discovery to your host computer using the USB port. Then build and flash an application. Here is an example for the Hello World application.
Run a serial host program to connect with your Nucleo board:
$ minicom -D /dev/ttyACM0
Then build and flash the application.
# From the root of the zephyr repository
west build -b stm32l562e_dk samples/hello_world
west flash
You should see the following message on the console:
Hello World! stm32l562e_dk
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b stm32l562e_dk samples/hello_world
west debug
