Bin2s19 Jun 2026

You can now load app.s19 into , Segger J-Flash , or Texas Instruments Uniflash without manually specifying the base address.

Let’s walk through a real-world scenario: You have a 64KB binary app.bin for an STM32 microcontroller that must be placed at 0x08004000 .

An S-record file is human-readable. It breaks the binary data into lines, each containing:

def bin2s19(data, base_addr, record_type='S1'): addr_bytes = 'S1':2, 'S2':3, 'S3':4[record_type] lines = [] for i in range(0, len(data), 32): chunk = data[i:i+32] addr = base_addr + i addr_bytes_list = addr.to_bytes(addr_bytes, 'big') count = len(addr_bytes_list) + len(chunk) + 1 line = [record_type, f"count:02X"] line.append(addr_bytes_list.hex().upper()) line.append(chunk.hex().upper()) payload = bytes([count]) + addr_bytes_list + chunk checksum = (0xFF - (sum(payload) & 0xFF)) & 0xFF line.append(f"checksum:02X") lines.append('S' + ''.join(line)) # Termination lines.append(f"S93:02X0:04X((0xFF - (3+0)&0xFF)&0xFF):02X") return '\n'.join(lines) You can now load app

The utility is typically run via the command line with the following basic structure: BIN2S19 [input_file.bin] [output_file.s19] [offset_in_hex] Description file containing the compiled firmware machine code. A hex value (e.g., ) defining the target memory address.
