Uf2: Decompiler
that gives back your source code. What you can do is extract the machine code → disassemble → decompile to rough C using Ghidra. The result will be functional but far from the original – useful for security analysis or low‑level learning, not for recovery of nice, readable code.
: Most professionals use Ghidra or IDA Pro . You can load the unpacked .bin file, specify the base address (typically 0x10000000 for RP2040 flash), and select the ARM Little-endian architecture to see the assembly or pseudo-C code .

Using lifter libraries (like remill or mcsema ), we can convert the ARM Thumb instructions into . Once in LLVM IR, we can run optimization passes to simplify the mess: that gives back your source code
A is used to reverse-engineer UF2 files, which are common USB flashing formats for microcontrollers like the Raspberry Pi Pico. Because UF2 files contain compiled machine code (binary), "decompiling" them typically happens in two stages: first, converting the UF2 back into a raw binary format, and then disassembling that binary into human-readable assembly or C code.
