How to get a full sysupgrade, out of segments

Ahoy friends.
Currently i'm trying to get a new OpenWRT image compiled for my TP-Link EAP120v1.
Unfortunately after compiling, i only receive a few files like vmlinuz.bin, lzma.elf and stuff like that.
How can i get a full "sysupgrade.bin" file out of that?

You should post all the changes you made here so others can have a look and help.

Stupid question but are you looking in the right folder? bin/target...?

It looks like that

So only in case of an ext4 image, i get a "full" image. The squashfs is weird.

I've used make right now, using verbose output, and according to it, the sysupgrade.bin is being deleted by the build script.
How can i prevent it of being deleted?

So it tries to copy the sysupgrade.bin to the destination folder, but afore it's being deleted? Doesn't make sense.
