During November 2024, Xiaoli Ji focused on platform hardening and memory protection improvements for the i.MX RT118x within the kholia/zephyr repository. She addressed issue #80721 by implementing a fix to the MPU memory region mapping, correcting base addresses and sizes for FlexSPI2, DTCM, FlexSPI, and peripheral memory regions. This update enhanced address space protection and improved overall memory management. Working primarily in C, Xiaoli applied her expertise in device drivers and embedded systems to update the MPU configuration in the soc: nxp: imxrt118x area. Her work demonstrated careful attention to low-level system integrity and security.
