MIPS交叉编译错误：非法指令

我想为MIPS机器交叉编译C src，但编译失败。 在目标机器上执行交叉编译的二进制输出“非法指令”。 你能不能让我知道如何编译MIPS机器的C src？

详情如下：

执行“readelf -h host.bin”（host.bin是在HOST机器上运行的二进制程序）输出：

ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: EXEC (Executable file) Machine: Intel 80386 Version: 0x1 Entry point address: 0x8048aac Start of program headers: 52 (bytes into file) Start of section headers: 8628 (bytes into file) Flags: 0x0 Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 9 Size of section headers: 40 (bytes) Number of section headers: 30 Section header string table index: 27 

执行“readelf -h target.bin”（target.bin是运行在目标机器上的二进制程序）输出：

• 错误设置去交叉编译
• configuration单声道进行交叉编译，什么进入 – 主机？
• 交叉编译：无法parsing符号'register_printf_function'
• 如何交叉编译Openwrt的.c文件？
• gcc连接器（ld）找不到共享库

执行“readelf -h cross_compiled.bin”输出（cross_compiled.bin是由目标机器交叉编译的二进制文件）：

 ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: EXEC (Executable file) Machine: MIPS R3000 Version: 0x1 Entry point address: 0x400170 Start of program headers: 52 (bytes into file) Start of section headers: 16444 (bytes into file) Flags: 0x1007, noreorder, pic, cpic, o32, mips1 Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 5 Size of section headers: 40 (bytes) Number of section headers: 21 Section header string table index: 20 

对于交叉编译，我使用了支持MIPS1交叉编译的buildroot。

我期望cross_compiled.bin在目标机器上正常执行。 但是，在目标机器上执行“cross_compiled.bin”时，输出“非法指令”。

你能不能让我知道如何解决上述问题？ 由于我是新手交叉编译，我找不到问题的确切原因。

任何意见将不胜感激。

更新：

在目标上，执行“cat / proc / cpuinfo”输出：

 system type : Broadcom BCM5354 chip rev 3 processor : 0 cpu model : BCM3302 V2.9 BogoMIPS : 237.56 wait instruction : no microsecond timers : yes tlb_entries : 32 extra interrupt vector : no hardware watchpoint : no VCED exceptions : not available VCEI exceptions : not available unaligned_instructions : 1 dcache hits : 0 dcache misses : 0 icache hits : 0 icache misses : 0 instructions : 0 

在目标上，执行“cat / proc / version”输出：

 Linux version 2.4.20 (ronger@ronger-linux.sh.deltagroup.com) (gcc version 3.2.3 with Broadcom modifications) #1 Tue May 22 17:40:19 EDT 2007 

我用于交叉编译的命令行（cross_compiled.bin）：

 mipsel-linux-gcc -static -o cross_compiled.bin cross_compiled.c 

cross_compiled.c：

 #include <stdio.h> int main() { printf("Hello World\n"); return 0; } 

由于我的cross_compiled.c非常简单，我相信不存在与使用的库相关的问题。
