Embedded Firmware for Hardware That Has to Ship

CLI Systems takes on the MCU and firmware work other shops turn down, from bringing up a brand new part to rescuing the legacy code nobody left understands.

Does This Sound Like You?

If one of these is your week, you are in the right place. Pick the one that fits and see how we help.

Out of Flash or RAM

"We need to add a feature, but there is no room left on the chip."

We reclaim flash and RAM through deep code archaeology and architectural optimization. Often 10 to 50 percent recovered, with no hardware redesign.

The Developer Who Knew Is Gone

"Nobody here understands how the firmware actually works anymore."

We reverse engineer and document legacy codebases, then hand back a system your team can own with confidence.

A New MCU to Bring Up

"We picked a part and need someone to write the drivers and get it running."

Production firmware in C and C++: peripheral drivers, communication stacks, bootloaders, and RTOS integration. Clean code, not future tech debt.

A Build System That Won't Build

"The only machine that can compile this is from 2008 and it is dying."

We containerize and resurrect ancient toolchains so your firmware builds on modern hardware again, with the whole process documented.

Embedded Linux That Barely Boots

"Our BSP is a mess and we need it production ready."

Kernel, device trees, custom drivers, Yocto and Buildroot. From first boot through OTA updates, the full stack from kernel to user space.

Time to Build the Whole Product

"We have an idea and need it taken all the way to production."

Turn-key OEM development from concept to manufacturing, with per-unit pricing and minimal upfront engineering cost.
