Specific Software Requirements

STM32_Programmer_CLI is required.(see https://www.st.com/en/development-tools/stm32cubeprog.html)

Write software on target

In secure build folder directory api_ns:

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

regression.sh: Sets platform option bytes config and erase platform

TFM_UPDATE.sh: Writes bl2, secure, and non secure image in target

Connect board to USB and Execute the 3 scripts in following order to update platform: postbuild.sh, regression.sh, TFM_UPDATE.sh

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

Baud rate = 115200

Data = 8 bits

Parity = none

Stop = 1 bit

Flow control = none
