Hi,
I have built the image for raspberrypi4 and i have got the following images

and  i am trying to copy ** core-image-minimal-raspberrypi4.wic.bz2 *by using*
**
*$sudo dd if=core-image-minimal-raspberrypi4.wic.bz2 of=/dev/sdb*
**
but my image is not getting copied into sd card(used two sd cards ,tried formatting with FAT,Linux),i am missing anything ,do i need to copy anything else with this core-image-minimal.
which extension of image i should use to bringup my RPI4??
**
Thanks!

Hello Pankaj,

  Try below mentioned steps, Hope it helps you, (there my image
was"core-image-base-raspberrypi3.rpi-sdimg"  replace it by your image )


plug sd card to pc then

$: lsblk
$: sudo umount /dev/sdb*

$: sudo dd
if=tmp/deploy/images/raspberrypi3/core-image-base-raspberrypi3.rpi-sdimg
of=/dev/sdb bs=4M

  >> This task will take some time and at the end we will get the output
something similar(not exact it depends on build files) to below :

        46+0 records in
46+0 records out
192937984 bytes (193 MB, 184 MiB) copied, 10.2155 s, 18.9 MB/s

You should have core-image-base-raspberrypi3.rpi-sdimg this should be
written to to the SD card. Please check it by following below steps. Hope
this help you.



then follow below steps to write the image on SD card.


SD_image writing



In build directory :
to check the sdimage for installing on SD card.

ls tmp/deploy/images/raspberrypi3/core-image-base-raspberrypi3.rpi-sdimg



plug sd card to pc then

$: lsblk
$: sudo umount /dev/sdb*

$: sudo dd
if=tmp/deploy/images/raspberrypi3/core-image-base-raspberrypi3.rpi-sdimg
of=/dev/sdb bs=4M

Siddhartha, you're confusing the issue here by giving inaccurate advice.

The original command posted by Pankaj was nearly correct: `sudo dd
if=core-image-minimal-raspberrypi4.wic.bz2 of=/dev/sdb`. The only
issue is that the data in the wic.bz2 file needs to be de-compressed
before writing to an SD card.

I recommend installing bmap-tools and using that to copy the data, it
handles decompression automatically and uses the block map in the
wic.bmap file to allow it to only write blocks which actually contain
data (saving lots of time that would be otherwise wasted writing
blocks of zeros). You can run `sudo bmaptool copy
core-image-minimal-raspberrypi4.wic.bz2 /dev/sdb`.

Thanks,
Paul

Am soory paul,

 But i was actually trying to check if sdimage is generated or not. I was
unaware of . wic. bz2 image. So suggested the above commands.

Sorry pankaj.


Thanks
