Worked on platform hardening and memory protection enhancements for the kholia/zephyr repository, focusing on the i.MX RT118x platform. Addressed a memory region mapping issue by updating the Memory Protection Unit (MPU) configuration to correct base addresses and sizes for FlexSPI2, DTCM, FlexSPI, and peripheral regions. This fix improved address space protection and resolved issue #80721, ensuring more robust memory management. The work involved in-depth knowledge of embedded systems and device drivers, utilizing C to implement and document the changes. The update contributed to safer memory access and better system reliability within the embedded software environment.
