Thanks so much Gary! I pulled in just logging and codecs modules and my image went from 22 MB down to 9MB, and the app is still working. I'm hopeful I can keep the ramdisk image under 16MB now. Moving on to install and configure flask and uwsgi to serve the app now. Speaking of which, how do you assign static IP instead defaulting to DHCP, and get ssh keys into the rootfs instead of Drpbear generating them every bootup? Can this be accomplished through Yocto or do you have to mount and modify the rootfs manually? -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
