Key Responsibilities

- Maintain and enhance the Yocto BSP for the TechNexion PICO-IMX6 DualLite (NXP i.MX6) platform.
- Assess and execute migration from Yocto Zeus to a newer LTS release (e.g., Dunfell/Kirkstone).
- Integrate reliable Linux kernel patches from NXP and mainline.
- Optimize system boot time, startup sequence, and overall performance.
- Remove unnecessary services and packages to reduce image footprint.
- Update and stabilize the Bluetooth stack (BlueZ and firmware).
- Optimize Linux kernel configuration, power management, and CPU tuning.
- Debug CPU, memory, storage, and I/O performance issues.
- Maintain Yocto layers, build process, and technical documentation.
- Define and maintain eMMC/SD storage layouts for boot, rootfs, data, and update partitions.
