Installing on SDcard
In order to install an image, you must identify your device ID. Check it as follows:
blkid -o list
This is an output example:
user@laptop:~$ blkid -o list
device fs_type label mount point UUID
--------------------------------------------------------------------------------------------------------------------------------
/dev/sda1 ext4 / 819c76f8-187f-46e9-b0c0-350032625bb3
/dev/sda3 ext4 data /media/gfallas/data 571e7aea-202e-4daa-8071-a1fc1207f458
/dev/sda5 swap [SWAP] 4018cfb5-4201-4656-a005-4fe04d06dde1
/dev/sdb1 ext4 USB_STICK (not mounted) d452f917-25c8-46a2-9b6e-4a58dcb1e8f1
Considerations
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.
Also, the device must be not mounted to successfully write the image.
If the required device appears with an mount point, unmount each partition with umount command.
PARTITION=/dev/sdb1 # The device may change in your system
sudo umount $PARTITION
Installing
Yocto supports several image formats, as example ext4, img and wic.
Those files will be created in <Yocto_Dir>/build/tmp/deploy/images/nitrogen8m.
Recent Yocto versions (Sumo and newer) have wic image type as default format, use bmaptool as follows:
IMAGE=fsl-image-multimedia-full-nitrogen8m.rootfs.wic
DEVICE=/dev/sdb # The device may change in your system
sudo bmaptool copy $IMAGE $DEVICE --nobmap
