Description
This script should be used to generate a device configuration text file which requires 32Bit CRC's and SHA-256 to be added for the Fuse Bits itself
It generates a standard 32Bit CRC with polynomial 0xedb88320 on the Fuse Bits from input device configuration text file and adds to appropriate location in the output file
It generates a SHA-256 Hex Digest on the Fuse Bits from input device configuration text file and adds to appropriate location in the output file
The generated output device configuration text file can be used by respecive bootloader host utilities to send the Fuse bits to bootloader using device configuration command
Refer to Bootloader Device Configuration Input section for details on creating the Device Configuration Input text file required by the utility
