PROFILE

Milan Krstic

Contributed to the DragonBluep/openwrt repository by developing and enhancing embedded Linux firmware for Qualcomm-based devices, including the TCL LINKHUB HH500V. Delivered new device support through device tree configuration, firmware adjustments, and kernel backporting, ensuring compatibility and stable operation on ipq807x platforms. Addressed kernel scheduling and modem stability issues by implementing targeted bug fixes in C and shell scripting, such as enabling can_sleep on GPIO expanders and correcting MHI IRQ vector allocation for PCI compliance. Improved upgrade reliability by refining bootconfig partition management and sysupgrade scripts, resulting in smoother deployments and reduced manual intervention for production hardware environments.
