Here is where the "decompiler" starts to look like a "recompiler." We map the binary to the chip's memory map. For an RP2040, Flash starts at 0x10000000.
Our script reads the raw binary, loads it at the base address, and runs Capstone in CS_MODE_THUMB. uf2 decompiler
But raw assembly is not a decompiler. Assembly is just slightly faster machine code. We need to lift to a higher intermediate representation (IR). Here is where the "decompiler" starts to look
Even with Ghidra or IDA Pro, decompiling a UF2-derived binary will never give you the original source code. Here is why: Then load each contiguous chunk at its correct
Some UF2 files contain blocks for different memory regions (e.g., flash at 0x00000000 and a small patch to RAM at 0x20000000). Ghidra supports memory overlays or you can split the binary into multiple files.
Use the --serial output from uf2conv.py to see address ranges:
uf2conv.py firmware.uf2 --info
Then load each contiguous chunk at its correct address in Ghidra.
