I have a zyxel VMG8825-B50B with ssh root access etc... Zyxel built It on top of OPENWRT. It Is basically OPENWRT with some drivers and little software added. My plan is to add opkg because It was disabled at compilation point. I downloaded the source code from zyxel mail and I managed to recompile the firmware with opkg, but there are some problems with flashing.
Since the only thing I want is opkg I'm asking If It Is possibile to compile only opkg and load it in the existing OPENWRT installation. I read the documentation about compiling only modules, but at the end the ipk file is installed with opkg
