   I have following binaries

• Linux OS kernel image (zImage)

• Device tree file (*.dtb)

• U-Boot bootloader image

• Root file system (*.ext3 or *.ext4)


How I can create an .sdcard image, which contains all these four images properly configured for an SD card by manually in my Ubuntu PC? What command I can use? If you have any script it is more helpful.


When I searched this question, I got the link Guide to the .sdcard format . But he explained configuration in yocto to build .sdcard image.

In yocto build I found IMAGE_FSTYPES="tar.bz2 ext3 sdcard" in some .conf file. But I didn't get where is the script to generate .sdcard image.


I want to do .sdcard image manually in my Ubuntu PC with the commands .


Thanks and Regards
