Objcopy can be used to convert an object to the S-record or raw binary format.
For example,
XXXX-elf-objcopy-o srec test. O test. S19
Convert test. O to the S-record file. It usually involves text segments.
XXXX-elf-objcopy-O binary test. O test. Bin
Convert test. O to the raw binary file format.
When converting an object to a raw bina
