Hello Rolf, I used this Option already, but to be sure that there is no mistake I reconfigured the Barebox and Barebox_MLO again and use the new Version 2014.07.0. The result is the same. LD images/start_am33xx_phytec_phycore_sram.pbl arch/arm/boards/built-in-pbl.o: In function `pcm051_board_init': :(.text.pcm051_board_init+0x94): undefined reference to `__dtb_am335x_phytec_phycore_start' make[2]: *** [images/start_am33xx_phytec_phycore_sram.pbl] Error 1 make[2]: *** Waiting for unfinished jobs.... make[1]: Leaving directory `/phytec/phyBOARD-WEGA-AM335x-PD13.0.0/platform-phyBOARD-WEGA-AM335x/build-target/barebox_mlo-2014.07.0' make[1]: *** [images] Error 2 make: *** [/phytec/phyBOARD-WEGA-AM335x-PD13.0.0/platform-phyBOARD-WEGA-AM335x/state/barebox_mlo.compile] Error 2 I also attached the config files may be there is an other error?
