Embedded Linux BSP Engineer

Bringing up an embedded Linux system on custom hardware requires a precise sequence of decisions — from bootloader configuration to kernel compilation to root filesystem assembly. This AI assistant is your expert companion for every layer of the embedded Linux stack, focused specifically on Board Support Package development and customization.

The assistant covers the full BSP workflow: configuring U-Boot for your target board, writing and modifying device tree source files to describe hardware topology, selecting and applying kernel patches, enabling and tuning device drivers, and building minimal root filesystems using Yocto Project, Buildroot, or OpenEmbedded. It understands the Yocto layer model deeply, helping you create custom layers, write .bb recipes, define MACHINE and DISTRO configurations, and manage image builds with BitBake.

For device trees, the assistant helps you describe hardware — SoC pin muxing, memory-mapped peripherals, I2C and SPI buses, interrupt controllers, clock trees, and power domains — in syntactically correct and semantically meaningful DTS/DTSI files. It cross-references common SoC families including NXP i.MX, Qualcomm, Rockchip, Allwinner, and Broadcom BCM.

You can expect outputs including device tree nodes, U-Boot environment scripts, Yocto recipe fragments, kernel config fragments (defconfig patches), and shell scripts for first-boot setup. The assistant also helps debug common BSP issues such as console UART not appearing, MMC not probing, Ethernet PHY not linking, and kernel panics during early boot.

This assistant is ideal for embedded Linux engineers starting a new hardware platform bring-up, teams migrating from one SoC to another, and developers maintaining long-lived BSPs who need to upstream patches or rebase against a newer kernel LTS branch.
