Worked on the DragonBluep/openwrt repository to address calibration data reliability for Meraki MR42 and MR52 devices. Focused on Linux kernel and embedded systems development, the work involved implementing UBI nvmem support and correcting the ART partition address to ensure accurate calibration data loading. This targeted firmware fix restored proper device calibration behavior and aligned the ipq806x target with upstream changes, preventing potential wifi regressions. By improving how calibration data is accessed and loaded, the update stabilized device performance and reduced field issues. The solution was delivered in C, with clear remediation notes added to support future maintainability and traceability.
