I followed the following steps to create and flash the image: - git clone -b dunfell git://git.yoctoproject.org/poky - cd poky - MACHINE="beaglebone-yocto" bitbake core-image-full-cmdline - sudo dd if=tmp/deploy/images/beaglebone-yocto/core-image-full-cmdline-beaglebone-yocto.wic of=/dev/sdc bs=4096 Unfortunately, I'm stuck on a line that repeats itself every five minutes: INIT: Id "AMA0" respawning too fast: disabled for 5 minutes Here is the complete log: https://pastebin.com/Hc3aqE1p Thank you for your help 87141 1 delete 2020-05-04 06:13:09 +0000 Additionally, here are the contents of the extlinux.conf (original) file, located in the boot partition at /extlinux : default Yocto label Yocto kernel /zImage fdtdir / append root=PARTUUID=01139ec5-02 rootwait console=ttyS0,115200 87142 2 delete 2020-05-04 07:21:45 +0000 I don't have this problem with the core-image-minimal 87182 3 kexin.hao 2020-05-13 00:55:00 +0000 I can't reproduce this on my side, we have set the SERIAL_CONSOLES_CHECK for this machine, so it should delete the nonexistent tty devices from the /etc/inittab in the first boot.
