我终于成功地从这个站点安装了一个交叉工具链，以便在我的 x86-64 上运行和调试 mips elf。我只有精灵文件。我可以拆卸它，但是当我尝试使用以下命令运行它时：
mipsel-none-elf-run myelf
我收到以下错误：
mips-core: 4 byte read to unmapped address 0x400670 at 0x400670
program stopped with signal 10 (User defined signal 1).
（地址 0x400670 指向主函数的第一条指令。
指定工具的字节序会给我同样的错误。
我试图运行它
mipsel-none-elf-gdb myelf

我使用目标 sim 和 load 来配置 gdb。但是当我想运行程序时。我得到：

程序收到信号 SIGBUS，总线错误。0x00400670 在 ?? () (gdb)
