Generally, the console setting comes from our <machine>.conf. eg: for beaglebone: ./meta-yocto-bsp/conf/machine/beaglebone-yocto.conf: SERIAL_CONSOLE = "115200 ttyO0" This gets processed in bitbake.conf: SERIAL_CONSOLES ??= "${@d.getVar('SERIAL_CONSOLE').replace(' ', ';')}" later, based on the init manager: busybox, systemd-serialgetty, or sysvinit-inittab use it. In this case, updating the "<machine>.conf" should help. >Thanks in advance, all the Best, >Jakob > >-- >Jakob Hasse >Software Developement > >E: jakob.ha...@smart-home-technology.ch >T: +41 44 552 02 66 > >Smart Home Technology GmbH >www.smart-home-technology.ch Best Regards, Maxin -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
