Converting flat binary into ARM ELF format

# The part .data=0x08000000 should be replaced with the correct base offset of the ROM.
# The value 0x08000000 is valid for STM32.
arm-none-eabi-objcopy -I binary -O elf32-little --change-section-address .data=0x08000000 input.bin output.elf

 转换有问题，改成

RISCV64-UNKNOWN-ELF cross-compilation tool for RISC-V instruction set

The following environments are performed in the liunx ubuntu x86_64 environment, and the following examples are used to generate a 32-bit file as a target.

• The ELF file is mainly a target file that is often used under x86linux.
• BIN file is a direct binary file, there is no address tag internally
• HEX files are often used to store programs or data transfer to ROM, EPROM, most programmers, and emulators using Intel HEX files.

Summary: You can translate into other two files by the ELF file, and HEX can also be converted to a bin file, but BIN is to be converted to the HEX file. You must give a base address. HEX and BIN cannot be converted to an ELF file because the amount of information of ELF is large.
