This is definitely not a good idea on rpi0/1. Let's select this based on RPI version: CMA_USAGE_raspberrypi = "cma-128" Or we can set a default variable on this configurable by user. But I would like to have a warning mechanism. Maybe a python function that will check if we want to build rpi1 and cma-256 was selected issue a warning. > + fi > } > > addtask deploy before do_package after do_install > -- > 2.7.4 > > -- > _______________________________________________ > yocto mailing list > [email protected] > https://lists.yoctoproject.org/listinfo/yocto -- Andrei Gherzan
