You suggest to use different MACHINEs of one SOC_FAMILY, Right? But if I bitbake the root filesystem for each MACHINE an *own* image is created. And not *one* usable for all of them. What we wish is one image containing one kernel and device tree files for each product. In addition a u-boot image for each product so that we can use a boot setup running different u-boot images starting the same kernel and root filesystem with different parameters (e.g. for the device trees). - -- DResearch Fahrzeugelektronik GmbH Otto-Schmirgal-Str. 3, 10319 Berlin, Germany Tel: +49 30 515932-237 mailto:sledz@dresearch-fe.de Fax: +49 30 515932-299 Geschäftsführer: Dr. Michael Weber, Werner Mögle; Amtsgericht Berlin Charlottenburg; HRB 130120 B; Ust.-IDNr.
