PROFILE
Joseph Guo
Qijian Guo developed initial board support for the FRDM-IMX91 platform in the flipperdevices/u-boot repository, focusing on device tree configuration and DDR memory initialization. He implemented device tree entries to enable peripheral connectivity and power management, and created DDR support for both 1GB and 2GB configurations, including timing scripts and initialization routines. Working primarily in C and dts, Qijian applied his expertise in Linux kernel and device driver development to ensure robust hardware interfacing for embedded systems. The work addressed the need for reliable board bring-up, providing a foundation for further development and documentation within the embedded Linux ecosystem.
