Good question. Depends which flux.ai you meant — but assuming you meant the PCB‐design platform at flux.ai (not a machine-learning “Flux” model):
Short answer: Yes — you can absolutely use Mender + Buildroot/Yocto firmware on devices whose PCBs you design in Flux.ai. But Flux.ai itself is for hardware design, not for running or managing firmware.
Here’s how the pieces relate, and how you can make them work together:
How Flux.ai and Mender / Embedded Firmware Fit Together
-
Flux.ai → Hardware Design
-
Flux.ai is a browser-based PCB design tool. LinkedIn+2Flux+2
-
It has a large component library (microcontrollers, sensors, regulators, etc.). Flux
-
Use Flux.ai to design your circuit board, pick components, place MCU, power system, connectors, etc.
-
-
Firmware Development (with Buildroot or Yocto)
-
Once you design your PCB, you’ll build firmware that runs on the microcontroller or application processor on that board.
-
For Linux-capable MCUs / SoCs, you might use Buildroot or Yocto to build your OS + application.
-
You write your firmware, compile it, test it, and generate a binary (or .elf, or Linux image).
-
-
OTA / Device Management with Mender
-
If you use Buildroot or Yocto, you can integrate Mender to handle over-the-air updates.
-
Mender ensures that you can push firmware updates, rootfs updates, or application updates to the devices you made with the PCB designed in Flux.ai.
-
Example Workflow
Here’s a simple end-to-end workflow combining Flux.ai, Buildroot, and Mender:
-
Design the PCB
-
In Flux.ai: Choose an MCU (e.g. NXP i.MX, STM32MP1, or a low-power MCU)
-
Add power supply, sensors, connectors, and other parts
-
Export Gerber + BOM
-
-
Manufacture the Board
-
Send Gerber files + BOM to a fab (JLCPCB, etc.)
-
Get assembled boards
-
-
Develop Firmware
-
Use Buildroot or Yocto to build Linux OS + your application
-
Compile your app (C, C++, Python, whatever)
-
Test on dev board
-
-
Integrate Mender
-
Add Mender client in your Buildroot / Yocto build
-
Configure A/B partitioning, artifact generation
-
Build Mender artifacts (.mender files)
-
-
Deploy and Manage
-
Flash devices initially via JTAG, SD, or USB
-
Register devices to your Mender server
-
Use Mender to push updates to your field-deployed devices
-
Important Considerations / Risks
-
Flux.ai is not an IoT device management platform — it does not manage firmware updates.
-
Using Flux.ai only covers the hardware design part, not the software side.
-
You need to make sure the components you choose in Flux.ai are well-supported by your firmware toolchain (e.g. Linux, drivers, BSPs).
-
For production, you’ll need a good CI/CD pipeline for building firmware + OTA artifacts + testing.
-
Ensure proper hardware validation: power, thermal, EMC, etc.
Bottom Line
-
Yes, you can design your hardware in Flux.ai and then run Mender-managed firmware (built with Buildroot or Yocto) on that hardware.
-
No, Flux.ai itself is not involved in firmware updating or OTA — it’s purely for designing PCBs / hardware.
