STM32WBA65_DK

Discovery kit for IoT node with STM32WBA series https://www.st.com/en/microcontrollers-microprocessors/stm32wba52cg.html

Configuration and Build

GNUARM/ARMCLANG/IARARM compilation is available for this target. and build the selected configuration as follow.

The build configuration for TF-M is provided to the build system using command line arguments. Required arguments are noted below.

The following instructions build multi-core TF-M with regression test suites in Isolation Level 1.

cd <TF-M base folder>
cd <trusted-firmware-m folder>

git clone https://git.trustedfirmware.org/TF-M/tf-m-tests.git
git checkout <recommended tf-m-tests commit>

mkdir build_s && cd build_s

The following instructions build multi-core TF-M with PSA API test suite for the attestation service in Isolation Level 1 on Linux.

cd <TF-M base folder>

Write software on target

In build folder (api_ns):

postbuild.sh: Updates regression.sh and TFM_UPDATE.sh scripts according to flash_layout.h

regression.sh: Erases flash and configures option bytes on target

TFM_UPDATE.sh: Programs TFM secure and non-secure appli, and provisions target

Connects board to ST-Link USB, then executes the 3 scripts in following order, to program the target: postbuild.sh, regression.sh, TFM_UPDATE.sh

The virtual com port from STLINK is used for TFM Applications log and serial port configuration should be:

Baud rate = 115200

Data = 8 bits

Parity = none

Stop = 1 bit

Flow control = none

In case of target power-off, the TFM_UPDATE.sh script must be run to program bl2_shared_data RAM area again.
