Developed dynamic device tree overlay runtime support for the flipperdevices/u-boot repository, focusing on Snapdragon platforms. This work enabled runtime modification of the kernel device tree during Android boot flows, allowing changes such as redirecting system or vendor partitions to external storage without requiring a base device tree blob rebuild. The implementation involved allocating a dedicated 1 MiB memory region for overlays when specific configuration options are enabled, ensuring compatibility and minimal impact on unsupported boards. The feature was developed in C, leveraging expertise in device tree management, embedded systems, and low-level programming, with code quality maintained through thorough review and traceability practices.
