In order to install an image, you must identify your device ID. Check it as follows:

blkid -o list

Device ID

Each device has numbers at the end, those numbers are related to partitions and they must not be specified to install the image. As example, instead of /dev/sdb1, use /dev/sdb.

Installing

Yocto supports several image formats, as example ext4, img, sdcard and wic.

In old Yocto versions, the most common image type was sdcard, use dd with this image type.

sudo dd if=<image.sdcard> of=/dev/<device> bs=4M && sync

Recent Yocto versions have wic image type as default format, use bmaptool as follows:

sudo bmaptool copy <image.wic> /dev/<device> --nobmap
