Decompiler: Uf2

What you will see:

: Sometimes Python code is "frozen" into the firmware. You might find plain-text Python or compiled bytecode ( .mpy ) within the binary. uf2 decompiler

# 5. Emit C c_code = emit_c_code(ir_module) return c_code What you will see: : Sometimes Python code

Decompiler shows undefined functions, all data references are invalid. Solution: In Ghir dra, use the Memory Map → Add Block , then shift the binary. Or use addr2line -style heuristics: search for the string FLASH or ROM in the binary. We spend a lot of time talking about compilers

We spend a lot of time talking about compilers. We glorify the process of taking human-readable code and turning it into magic silicon dust. But what about the reverse? What about the binary artifacts left behind on a $4 microcontroller?

Since UF2 is a container format rather than a compiled language, "decompiling" usually happens in two stages:

In this blog post, we'll explore what a UF2 decompiler is, how it works, and provide an overview of some popular UF2 decompiler tools.
