riscv64-unknown-elf 为 RISC-V指令集的交叉编译工具
以下环境在Liunx ubuntu x86_64 环境下进行，下面示例以生成32位文件为目标来操作使用。
// watch IO infos screen /dev/ttyACM0 115200
// complie 64-bit file riscv64-unknown-elf-gcc -o file file.c // complie 32-bit file riscv64-unknown-elf-gcc -march=rv32imac -mabi=ilp32 -o file file.c
// pretreatment riscv64-unknown-elf-gcc -march=rv32imac -mabi=ilp32 -E -o file.i file.c // compile riscv64-unknown-elf-gcc -march=rv32imac -mabi=ilp32 -S -o file.s/file.S file.i // assembler riscv64-unknown-elf-gcc -march=rv32imac -mabi=ilp32 -c -o file.o file.s/file.S // link riscv64-unknown-elf-gcc -march=rv32imac -mabi=ilp32 -o file file.o // get ELF-file riscv64-unknown-elf-gcc -march=rv32imac -mabi=ilp32 -o file file.c // ELF to bin riscv32-unknown-elf-objcopy -O binary file file.bin // ELF to HEX riscv64-unknown-elf-objcopy -O ihex file file.hex // disassembler ELF to get ASM riscv64-unknown-elf-objdump -d file.elf > file.asm
总结：可以由ELF文件转化为其它两种文件，HEX也可以直接转换为BIN文件，但是BIN要转化为HEX文件必须要给定一个基地址。而HEX和BIN不能转化为elf文件，因为ELF的信息量要大。
