How to use bin2hex

bin2hex [-h] [-v] [-i INPUT] [-o OUTPUT] [-f FORMAT] [-a ADDRESS] [-A ALIGNMENT] [-e ECC]
        [--ecc-skip-all-ones] [--ecc-skip-all-zeros] [-c PAD_COUNT] [-b PAD_BYTE] [-s SPLIT]

options:
  -h, --help            Show this help message and exit
  -v, --version         Show version information
  -i, --input INPUT     [Required] The raw binary input file to be converted
  -o, --output OUTPUT   [Required] The formatted hex output file to be converted to
  -f, --format FORMAT   [Optional] The format to be converted to. Default is "vhex_dw1"
  -a, --address ADDRESS
                        [Optional] The start address of the image. Not all formats require. Default is
                        0x0

                        [Optional] The byte count per line. Default is various according to the format
  -e, --ecc ECC         [Optional] The ECC type to be calculated. Not all formats require. Default is
                        "none"
  --ecc-skip-all-ones   [Optional] Skip ECC calculation for all-ones data blocks. Useful for FLASH
                        memory with erased state as all-ones

Supported ECC Algorithm

1. None:

• No ECC is added

2. ARM SECDED(--ecc arm_secded):

• Single Error Correction Double Error Detection (SECDED) code
• The ECC bits are appended to the MSB side of the data
• Only verilog_dwx (x = 4, 8, 16) formats support this ECC

3. User specific algorithm(--ecc <custom_ecc_func.py>)

• Custom ECC function defined in the specified Python file
• The Python file should define a function named ecc_encode

def ecc_encode(data: bytes, data_width: int) -> bytes
    # Add user specific algorithm here
    return data + ecc_bytes

• data is the input data in bytes
• data_width is the data width in bytes
• The function should return the data with ECC bits appended to the MSB side in bytes
• Only verilog_dwx (x = 1, 2, 4, 8, 16) formats support this ECC
