PROFILE
Nguyen Tran
Worked on hardware enablement and security hardening for embedded platforms in the flipperdevices/u-boot repository. Delivered device tree and board-specific configurations in C and DTS to add Geist board support for the Renesas R8A779MD SoC, aligning with reference designs and preparing for upstream integration. Addressed security and reliability on the R8A779H0 Gray Hawk board by disabling RPC SPI control for QSPI Flash through targeted device tree changes, ensuring CR-side access as required. Collaborated with Renesas engineers for cross-team validation, producing well-documented, multi-signed commits. Demonstrated expertise in embedded systems, Linux kernel development, and device tree configuration for production hardware.

May 1, 2026May 2026 delivered critical hardware support for Geist on the Renesas R8A779MD platform within the flipperdevices/u-boot repository. Implemented device-tree configurations and board-specific settings for Geist (M3Le), enabling earlier field deployments and smoother customer onboarding. Prepared groundwork for upstreaming the design (OF_UPSTREAM) once upstream DTs land, with a well-documented commit that includes multi-signer sign-off from Renesas engineers.
