Thank you for your input. I have now solved the problem without changing to master. After creating a new build directory which does not include my own layer, I was able to build the vivante drivers. As it turned out, using the bbappend files to overwrite the COMPATIBLE_MACHINE variable was the wrong way to go. I have now removed the bbappend files and added the following line in the machine conf file within my layer: MACHINEOVERRIDES =. "mx6:mx6dl:" Then I cleaned and rebuilt the whole image and it worked without problems. Regards, Michael
