: Checking if a closed-source firmware is sending data where it shouldn't.

Navigating the Binary: A Deep Dive into UF2 Decompilers In the world of embedded systems and microcontrollers, the has become the gold standard for simplicity. Developed by Microsoft for PXT (MakeCode), it allows users to flash firmware by simply dragging and dropping a file onto a USB drive. However, what happens when you have a .uf2 binary but have lost the source code? This is where the quest for a UF2 decompiler begins. What is a UF2 File? uf2 decompiler

Even with advanced tools, the result is and often requires hours of manual annotation. : Checking if a closed-source firmware is sending
