Hello @saijanani.tx ,
I just started a build with ubuntu 18.04 which is meant to support (link) the version of m4-native in order to build the Toradex reference image 2.8b7.
Just to be able to have an image quickly available.
The procsess passed the point of m4-native build, so it looks good for now 
I will keep you updated, also with the config of the spi3 interface as for the usage of the Data Modul Colibri base board.
Thank you very much
Armin
