Uf2 Decompiler 【HOT】

Some UF2 files contain blocks for different memory regions (e.g., flash at 0x00000000 and a small patch to RAM at 0x20000000 ). Ghidra supports or you can split the binary into multiple files.

def main(): if len(sys.argv) < 2: print(f"Usage: sys.argv[0] firmware.uf2 [output.bin]") sys.exit(1) uf2_file = sys.argv[1] out_file = sys.argv[2] if len(sys.argv) > 2 else uf2_file.replace('.uf2', '.bin') blocks = parse_uf2(uf2_file) if not blocks: print("No valid UF2 blocks found.") sys.exit(1) print(f"Found len(blocks) blocks, family ID = 0xblocks[0]['family']:08X") firmware, base_addr = reassemble_binary(blocks) with open(out_file, 'wb') as f: f.write(firmware) print(f"Reassembled len(firmware) bytes -> out_file (base 0xbase_addr:08X)") uf2 decompiler

A naive approach in Python:
