PROFILE
Siwei Xu
Xusiwei contributed to the levizh/rt-thread repository by developing foundational support for the FRDM-i.MX91 board, implementing a dedicated Board Support Package that included configuration files, drivers, and a demonstration application. Using C programming and embedded systems expertise, Xusiwei established a complete bring-up workflow for the NXP i.MX91 platform, enabling rapid onboarding for new projects. Additionally, Xusiwei addressed a critical kernel virtual address space initialization bug for AArch64, ensuring correct memory mapping when KERNEL_VADDR_START is set to high addresses. The work demonstrated depth in RTOS development and low-level programming, improving both reliability and scalability for ARM64-based embedded systems.
