During May 2025, Evgeny Kovsky focused on kernel and bootloader reliability within the flipperdevices/u-boot repository, addressing a critical bug in ramdisk address assignment for header versions less than or equal to two. By analyzing memory addressing and kernel image integration, Evgeny implemented a fix in C that ensures the ramdisk is correctly assigned when the kernel and ramdisk share the same address, enabling successful boot on Renesas R-Car S4 hardware. This work improved hardware compatibility and reduced boot failures, demonstrating expertise in embedded systems, low-level programming, and kernel development while contributing to the ongoing stability of the platform.
