I'm just doing a dry run with some sample applications using the SDK and the command line and all is looking good. I didn't know about the "eclipse-debug" so I'll take a look at this. Sadly all the dev and dbg packages are probably not going to fit into the flash but I'll keep a copy of the dbg packages somewhere in case a developer wants to debug into a library. They can scp it onto their board and install it. If I also include gdbserver and lttng packages for the target then hopefully this should be a good start. Regards, Martin.

You need to make sure your image includes the features for debu= gging.=C2=A0 If you have an image that is based upon core-image-minimal, th= e image will be missing some features and you'll never be able to debug= an application through Eclipse or use Lttng.

I'd suggest making a development image recipe (i.e. "my-custom= -image-dev.bb") based on your image with the following changes: 1. Add "dev-pkgs eclipse-debug" to IMAGE_FEATURES
2. Add a "-dbg" package to IMAGE_INSTALL for each userspace appli= cation you are writing which you plan to debug with GDB.
3. Add "gdbserver" to IMAGE_INSTALL for GDB support.
4. Add "lttng-tools lttng-modules lttng-ust" to IMAGE_INSTALL for= Lttng support.

Once you've built and verified the new image runs on your hardware, I&#= 39;d then create the SDK as you described above.=C2=A0 I don't use QEMU= so I can't speak to whether that gets included in the SDK or not.=C2= =A0 But, if you have a developer that isn't responsible for building th= e whole image and just wants to build and debug their userspace application= , the SDK and resulting sysroot should be all the pieces they need on their= development machine.

Bryan
