Re: [LTP] How to test Linux Kernel using LTP on Beagleboard (ARM Cortex-A8 based board)

[G R. <G.R...@ln...>]

Hi Maxin,

Thank you very much for reply. Now I understand that I can execute the LTP on target board which tests linux kernel.

I have successfully installed Scratchbox1 and selected the armv7 target in sub-menu. I got shell prompt like "[ sbox- armv7  ~]". I have downloaded the LTP source "ltp-full-20100228.ar.gz" from LTP-web.

Can you please share the procedure of how to Cross-Compile the LTP source code using Scratchbox1 to generate the binaries for the beagleboard.

Thanks in advance for your time.

Rajender

Hi Rajender,

Qemu is a machine emulator. If you don't have a particular board, eg:
Beegleboard, you can emulate that board using qemu. So, preparing a cross-compiled binary for Qemu environment is exactly same for the target board.

Once you cross-compile the LTP (using scratchbox or directly using the cross-toolchain), you can transfer the cross-compiled binaries to the board. Transferring process might depend on your setup. Some might prefer to use NFS based user-land. Some might prefer transferring to the board using tftp, wget, ftp, etc. Otherwise, you can copy the LTP binaries to an SD card and then use that binaries from Beegleboard.
Using SD card might create some issues, if it's formatted with FAT file system (due to symbolic link issues for FAT in Gnu/Linux environment).

It's always better to press "Reply-All" option since this was previously discussed in a forum.

Best Regards,
Maxin B. John
