Introducing Soul Room: An Open-Source Edge Fleet Platform for Linux Devices
Meet Soul Room, an open-source platform for enrolling, monitoring, operating, updating, and securely accessing Ubuntu, Debian, Yocto, and embedded Linux fleets.
Blogs.
Ideas, diagrams, and notes from the embedded Linux workbench.
OP-TEE from Zero: Part 1
A beginner-friendly map of OP-TEE, ARM TrustZone, Trusted Applications, libteec, tee-supplicant, xtest, and the ARM secure boot flow.
Remotely Accessing Wayland-based Applications using RDP client in Yocto Image
Configure Weston, FreeRDP, TLS keys, and RDP clients to remotely access Wayland applications running in a Yocto image.
Scaling IoT fleets: Secure Reverse SSH into Yocto for Automated Field Deployment
Integrate ShellHub with Yocto to enable secure reverse SSH access, zero-touch provisioning, and fleet-scale onboarding for field devices behind NATs and firewalls.
Designing an update that knows when to stop
A useful OTA design begins with its failure states, not its progress bar. Map the boundaries before automating the happy path.
Starter note
Debugging containers without losing the evidence
Before restarting everything, capture the state that explains what happened. A small, read-only starting point for an investigation.
Starter note
A small map of the embedded Linux stack
Silicon, boot software, the kernel, userspace, and applications: a clearer picture of where each responsibility belongs.
Starter note
Make the build explain itself
A useful build record tells the next engineer what went in, what came out, and which assumptions were in play.
Starter note
Security starts before the application
Boot integrity, runtime isolation, and credential handling solve different problems. Draw the boundaries before choosing the mechanism.

Hello, Edge Systems Lab. A place for useful ideas.
A small, maintainable home for engineering notes. Write Markdown, push a commit, and let the publishing workflow do the rest.
