Portfolio
Client details are anonymized per NDA.
Secure Embedded Linux Platform
Yocto-based distribution with secure boot and production signing.
- Industrial IIoT device requiring tamper-evident firmware and field update capability
- Technologies: Yocto Project, U-Boot, OP-TEE, dm-verity, PKCS#11 signing infrastructure
Outcome: platform passed security review and entered production release
Linux Kernel Development
Kernel configuration, device tree enablement, and panic triage.
- Target kernel in the 6.x LTS series; subsystems covered include USB, SPI, and regulator framework
- Resolved device tree conflicts blocking bring-up and traced root cause of intermittent kernel panics under load
Outcome: stable mainline-tracking kernel shipped with the product BSP
Zephyr RTOS Board Port
Full board bring-up and driver enablement.
- STM32-based MCU with I2C sensor array, SPI flash, and UART debug console
- Enabled board definition, pinmux, DTS, and upstream-compatible driver bindings
Outcome: board merged into project tree; firmware running in production
BSP & Board Bring-up
New hardware enablement and platform integration.
- NXP i.MX8-based SoC bring-up from cold silicon to running Linux userspace
- Brought up U-Boot SPL, ATF, and Linux kernel with full peripheral tree
Outcome: time-to-first-boot achieved within engagement milestone; BSP handed off with full documentation
