We maintain the code your product runs on.
Linumiz engineers are named maintainers in Zephyr RTOS and Linux - for the TriCore architecture, TI MSPM0 and Infineon AURIX platforms and the OCPP stack - with 450+ changes merged across Zephyr, Linux, U-Boot, Yocto and OP-TEE. Your drivers land upstream, so your product doesn't carry patches forever.

Areas we maintain upstream
Maintainers review and merge everyone else's changes in their area. When your silicon or protocol is in our area, you are working with the people who sign off on it.
Also collaborators for Infineon platforms & HAL and Nuvoton NuMaker platforms & HAL in Zephyr RTOS.
Where we contribute
Merged changes per project, with the trend year by year. Hover a bar for the exact count.
Zephyr RTOS
Drivers, board ports, subsystems and protocol stacks - including the native OCPP 1.6 stack upstreamed to the project.
Latest merged | Sep 2026 doc: release: Add note for Infineon TriCore additionLinux kernel
Device drivers, Trusted Keys and subsystem improvements upstreamed to mainline.
Latest merged | Dec 2024 pinctrl: sunxi: add missed lvds pins for a100/a133U-Boot
Board support, drivers and bootloader features upstreamed to the U-Boot project.
Latest merged | May 2021 imx: Add SeeedStudio NPI-IMX6ULL SupportYocto & Buildroot
Recipe and layer maintenance across OpenEmbedded, Yocto and Buildroot.
Latest merged | Sep 2024 bluez5_utils: disable asha profileSilicon we brought upstream
SoC support, boards and drivers we wrote and landed in mainline - so these chips work out of the box.
TI MSPM0
Zephyr SoC, boards & 20+ drivers
Infineon AURIX TriCore
New Zephyr architecture, NuttX & QEMU ports
Infineon TRAVEO T2G
Zephyr SoC & drivers
TI Tiva C
Zephyr SoC, board & drivers
NXP i.MX
U-Boot boards & Linux
Allwinner A133
Linux, TF-A & OP-TEE
Rockchip RV1109 / RV1126
Linux boards & bindings
Ambiq Apollo
Zephyr drivers
Infineon AURIX TriCore, upstream everywhere
One automotive CPU architecture, landed in Zephyr and now under review in NuttX and QEMU - so AURIX developers get an RTOS choice and a simulator from mainline.
