So i want to disassemble and then run a MIPS elf file for the first time. As i don't have MIPS hardware i am using mipsel-unknown-linux-gnu toolchain.Here comes the problem. The output of the command file myelf is:

ELF 32-bit LSB executable, MIPS, MIPS-I version 1 (SYSV), statically linked (uses shared libs), stripped

But when i try to disassemble the file i get:

mipsel-unknown-linux-gnu-objdump: myelf: File format not recognized

I get the same error when i want to run it or to debug it. But if i write a small program in MIPS assembly (using an edit and mipsel-unknown-linux-gnu-as as assembler and mipsel-unknown-linux-gnu-ld as a linker) i can run it and debug it so i'm sure the problem comes from myelf file. Actually i can disassemble myelf with IDA but i want to follow the execution using gdb under linux.

Then i did a readelf and this is the output of mipsel-unknown-linux--u-readelf -a myelf:

As it's a project from a school dealing with reverse engineering, the elf file may be corrupted or not. I have no idea from what the problem could come from. You can download myelf file from this link. Thank you.

Anyone have encountered this kind of error or any suggestions ?

    Some information is missing here. You don't have MIPS hardware, but you're able to write a small program in MIPS assembly and run it? In any case, a question that bascially asks "what's wrong with file X" has a much better chance of getting answered if a link to file X is included in the question. – Guntram Blohm supports Monica Apr 6 '15 at 19:04
  • Thanks, you were right i added the link file at the end of the question and the information about the mipsel-unknown-linux-gnu toolchain. – creuchmeuch Apr 7 '15 at 4:55

This file is completely valid ELF, but you have a problem with the toolchain. You should check correctness of its setup.

In addition if you don't have the hardware you can use qemu to run it. There is also aboriginal toolchain that you can try to use.

Output of the readelf should be as follows:
