Create SD card
Home / Tutorial Index / Getting started
Ref: http://git.yoctoproject.org/cgit.cgi/poky/tree/README.hardware
The exact device path to your SD card depends on your Linux distribution and computer setup. Use the command
$ df -h
with and without the SD card to see which device is created. Take care because one of the devices will be your Build machine disk and you dont want to accidently reformat the build machine! Let us suppose the SD card is /dev/mmcblk0p1
Now partition and format the SD card (notice the change of name to the raw device name without partition info):
$ sudo fdisk -lu /dev/mmcblk0
Disk /dev/sdb: 29.2 GiB, 31322013696 bytes, 61175808 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x000a07b6
Device Boot Start End Sectors Size Id Type
/dev/sdb1 2048 264191 262144 128M b W95 FAT32
/dev/sdb2 264192 14600191 14336000 6.9G 83 Linux
Now create the partitions
$ sudo mkfs.vfat -F 32 -n "boot" /dev/mmcblk0p1
$ sudo mkfs.ext3 -j -L "root" /dev/mmcblk0p2
Now copy the boot files to the boot partition
$ sudo mkdir -p /tmp/mmcboot
$ sudo mount -t vfat /dev/mmcblk0p1 /tmp/mmcboot
$ sudo cp tmp/deploy/images/parallella-hdmi/uImage /tmp/mmcboot/uImage
$ sudo cp tmp/deploy/images/parallella-hdmi/parallella-hdmi-mmc-boot-example.dtb /tmp/mmcboot/devicetree.dtb
$ sudo cp tmp/deploy/images/parallella-hdmi/bitstreams/parallella_e16_hdmi_gpiose_7020_base_example.bit.bin /tmp/mmcboot/parallella.bit.bin
Now create the root file system
$ sudo mkdir -p /tmp/mmcroot
$ sudo mount -t ext3 /dev/mmcblk0p2 /tmp/mmcroot
$ sudo tar xf tmp/deploy/images/parallella-hdmi/hdmi-image-example-parallella-hdmi.tar.gz -C /tmp/mmcroot
Now sync and unmount the SD card.. its ready to try on the parallella!
$ sync; sync
$ sudo umount /dev/mmcblk0p1
$ sudo umount /dev/mmcblk0p2
$ sync; sync
I suggest putting these commands into a script. As this is build machine specific I will leave that as an exercise for the reader!
