Worked on the flipperdevices/u-boot repository to address a kernel ramdisk address assignment issue affecting boot reliability on Renesas R-Car S4 hardware. Focused on embedded systems and kernel development, the work involved debugging low-level memory addressing in C to ensure the ramdisk is correctly assigned when the kernel and ramdisk share the same address, specifically for header versions less than or equal to two. This fix reduced boot failures and improved hardware compatibility across devices, supporting ongoing platform stability. Demonstrated expertise in kernel and bootloader debugging, as well as Android image integration, contributing to more robust embedded system deployments.
