Hi,
I have built the image for raspberrypi4 and i have got the following images 
 
 
core-image-minimal.env                                                              rpi-ft5406-1-4.19.120+git0+9da67d7329-r0-raspberrypi4-20200521111428.dtbo
core-image-minimal-raspberrypi4-20200518130120.rootfs.ext3                          rpi-ft5406.dtbo
core-image-minimal-raspberrypi4-20200518130120.rootfs.manifest                      rpi-ft5406-raspberrypi4.dtbo
 
core-image-minimal-raspberrypi4-20200518130120.rootfs.tar.bz2                       rpi-hwup-image.env
 
core-image-minimal-raspberrypi4-20200518130120.rootfs.wic.bmap                      rpi-hwup-image-

core-image-minimal-raspberrypi4-20200518130120.rootfs.wic.bz2                       rpi-hwup-image-
 
raspberrypi4-20200521111428.rootfs.manifest

core-image-minimal-raspberrypi4.wic.bz2                    
 
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!
