This is a tech blog focused on firmware, with occasional deep-dives into whatever I’m exploring. My goal is to connect with readers worldwide and grow a community that learns and builds together.
1. Introduction: What is Edge AI If you work in firmware, you have probably noticed that AI is no longer staying in the cloud. It is showing up in cameras, wearables, factory sensors, appliances, vehi
When people talk about embedded systems, the first things that usually come to mind are microcontrollers, C/C++, RTOS, device drivers, and Embedded Linux. FPGA is often treated as a separate field. Bu
One of the biggest misconceptions I see among junior embedded engineers is: “Every year I work in embedded systems, I’m building deeper technical expertise.” Sometimes that’s true. But sometimes what
A new board is on the bench. The power rails look reasonable, the debugger connects, and the firmware flashes without complaint. You press reset. Now what? Maybe an LED starts blinking. Maybe the debu
When Connecting is only the beginning An IoT gateway sits in the middle of a journey: receiving data, making sense of it, and delivering it somewhere useful. There is a particular moment every embed
What is secure boot? Secure boot is one of those topics that sits at the intersection of embedded software, system security, and real products. Everyone has heard of it. Many projects mention it. Fewe
Why reverse engineering matters If you’ve ever stared at a stripped firmware image and asked, “Where does this boot? What does it talk to? Why does it lock up?”—you’ve already brushed against reverse engineering (RE). I got into RE the same way many ...
SW/HW Co-Simulation—What It’s For and How We Do It Software/hardware co-simulation links executable software to a hardware model to verify behavior before silicon or FPGA bring-up. Teams use it at two levels: unit-level (e.g., HLS IP correctness and ...
1. Background & Motivation Modern RISC-V SoC development often demands parallel hardware and firmware progress. Waiting for RTL completion or silicon fabrication delays firmware bring-up and can mask integration bugs until late in the project. Tradit...
