Worked on stabilizing the test infrastructure for the zephyrproject-rtos/trusted-firmware-m repository, focusing on improving platform-specific compatibility for the STM32WBA6. Addressed a regression in the regression.sh script by aligning it with flash_layout.h, ensuring that protection and default option parameters matched the requirements of the target hardware. This Shell scripting adjustment reduced flaky regression outcomes and improved the reliability of continuous integration workflows. Leveraged skills in embedded systems and scripting to enhance test stability, supporting hardware bring-up efforts. The work contributed to more dependable regression testing and strengthened the platform’s readiness for further development and deployment activities.
