I installed gcc-arm-linux-gnueabihf cross-compiler on Ubuntu 12.04, and now I am able to build a program for embedded device. Where can I find cross gdb for debugging?

gcc-arm-linux-gnueabihf reference contains gdb-arm-linux-gnueabihf in the Related Packages list, which seems to be the debugger that I am looking for. But this package is not available.

  • Try toolchain from codesourcery.com/sgpp/lite/arm/download.html Commented Nov 7, 2012 at 12:41
  • @anishsane - Thanks, I have already tried it, but device vendor recommends gcc-arm-linux-gnueabihf. Now I need to find (or possibly to build) cross-debugger for this device. Commented Nov 7, 2012 at 12:48
  • @anishsane - can you recommend good embedded Linux forum? I don't post such question here, because such questions are immediately closed :( Commented Nov 7, 2012 at 12:51
  • I think, you can get in touch with community like beagle-board, etc. (It's a very active google group.) There you will get good help at least for arm+linux combination. It will be specific to beagleboard, but I think, for simple requirements, they can guide you. Commented Nov 7, 2012 at 13:49

I recommend getting gdb from the Linaro toolchain rather than the Ubuntu repositories. Download gcc-linaro-arm-linux-gnueabihf-4.7-2012.10-20121022_linux.tar.bz2 from here and you'll find:

  • bin/arm-linux-gnueabihf-gdb
  • arm-linux-gnueabihf/debug-root/usr/bin/gdbserver

The latter is statically linked and of course built for ARM Linux.

Assuming you have networking already set up to your target board, copy gdbserver to it and run:

$ gdbserver --multi :2345

On your development machine, run:

$ arm-linux-gnueabihf-gdb
(gdb) target extended BOARD-IP-ADDR:2345
(gdb) set remote exec-file /bin/true
(gdb) run

and you're up and running with remote cross debugging.

Links to the Linaro bug tracker, mailing list and web forum are here. They're very active in ARM Linux toolchain, kernel, QEMU development as you can see from their release notes.

Thanks, got it working. Nice to see that there are embedded developers in this forum.
For me arm-linux-gnueabihf-gdb doesn't start on a 64-bit machine do you know if it is only for 32bit?
@eactor, see askubuntu.com/questions/297151/…
ok somehow the output of the programm is issued to the target board instead of forwarded to the devlopment machine, is that normal and can i change it?
@eactor, ask that as a new question tagged with "embedded-linux" and provide details of how you're connecting to the target board and starting your program. The short answer is yes ;)

You need to install the gdb-multiarch package, then run gdb-multiarch command to remotely debug your target.

That solved it for me, thanks! I'd much rather install a package from the official repositories, than from a third-party website.
