generate_bin_blob.c

converts a binary file into C/C++ h-file code with versioning and dating. We use this converter to embed the device-tree overlays binaries and FPGA firmware binaries directly into the library code. In such way, the lib is self contained and doesn't have floating around dependencies.

Usage:

$ ./generate_bin_blob input_file.bin variable_name output_file.h

The output file will have the following structure:

#ifndef __cariboulite_dtbo_h__
#define __cariboulite_dtbo_h__

#ifdef __cplusplus
extern "C" {
#endif

#include <stdio.h>
#include <stdint.h>
