Worked on improving boot reliability for the J7200 target in the flipperdevices/u-boot repository, focusing on embedded systems and bootloader configuration using C. Addressed a critical boot failure by increasing the tiboot3.bin memory allocation from 512KB to 1MB in HyperFlash, preventing overlap with tispl.bin and ensuring a stable boot process. Updated the j721e_evm configuration to reflect the new memory offset, aligning with platform-specific hardware constraints. This targeted bug fix enhanced device reliability and reduced potential field failures, demonstrating careful attention to memory mapping and embedded bootloader best practices while contributing to smoother deployments and lower maintenance overhead.
