Worked on hardening Android boot image command-line handling in the flipperdevices/u-boot repository, focusing on improving correctness and reliability during the boot process. Addressed issues related to memory management by ensuring proper allocation and freeing of resources, specifically preventing memory leaks after command-line processing. Enhanced the construction and concatenation of boot arguments to avoid overflows and misprocessing, implementing robust logic for spacing and null termination. Utilized C for low-level bootloader development, applying expertise in embedded systems and kernel configuration. The work resulted in more reliable Android boot behavior by systematically reducing risks associated with improper command-line handling and memory misuse.
