PROFILE
Cibil Pankiras
Cibil Pankiras enhanced the flipperdevices/u-boot repository by implementing per-pin GPIO pull-up and pull-down control for BCM2835 and BCM2711 platforms, enabling device-tree based bias configuration for more reliable hardware initialization. Using C and leveraging Linux kernel and embedded systems expertise, Cibil updated the brcm283x pinctrl driver to support flexible, device-specific bias settings, improving boot-time stability and hardware configurability on Raspberry Pi variants. Additionally, Cibil addressed a macro inconsistency in reboot-mode-gpio.h, ensuring correct driver initialization by aligning macro references. The work demonstrated a strong grasp of driver development and maintainability, delivering targeted improvements within a focused development cycle.
