The answer seems to be > SW1-SW8=On/Off/On/Off/Off/On/Off/On) I have 2 riotboards both booting from sdcards, here are their configurations: - slot J6 (USDHC2), SW1-8 = On/Off/On/Off/Off/On/On/Off - slot J7 (USDHC3), SW1-8 = On/Off/On/Off/Off/On/Off/On > I get the U-Boot prompt from the image I built (it has today's date), > but the SD card doesn't boot from there.

Fido uses U-Boot v2015.04. Assuming that you haven't modifed the upstream version, v2015.04 uses extlinux boot mechanism, which requires the following files to be available on your boot partition: /boot/extlinux/extlinux.conf /boot/imx6dl-riotboard.dtb /boot/uImage Extlinux.conf should have the following content: default yocto label yocto kernel /boot/uImage devicetree /boot/imx6dl-riotboard.dtb append console=ttymxc1,115200 root=/dev/mmcblk0p1 rw Technically speaking, recent versions of U-Boot for riotboard are quite plug-and-play - as long as you have properly placed your extlinux files, the bootloader will automatically find them on any attached storage and boot as piece of cake (works also with rootfs on usb-disk). If you have partitioned the sdcard with a modern version of fdisk, the 1st partition will be properly located at 1MiB offset, thus leaving more than enough space for U-Boot. Hope this helps.
