  • dd를 이용하여 직접 Image 구성방법

//각 binary file을 mmcblk0에 직접 write  
$ dd if=sd_fuse/bl1.HardKernel of=/dev/mmcblk0 seek=1   //seek= 1x512 bytes (default 512byte) 
$ dd if=sd_fuse/bl2.HardKernel of=/dev/mmcblk0 seek=31  //seek= 31x512 bytes (default 512byte) 
$ dd if=u-boot.bin of=/dev/mmcblk0 seek=63
$ dd if=sd_fuse/tzsw.HardKernel of=/dev/mmcblk0 seek=2111

$ dd conv=notrunc seek=2455 bs=512 if=zImage of=/dev/block/mmcblk0

$ dd if=zImage of=/dev/mmcblk0 seek=1 //seek= 1x512 bytes (default 512byte) 
$ dd if= of=/dev/mmcblk0 seek=31
$ dd if=u-boot.bin of=/dev/mmcblk0 seek=63
$ dd if=sd_fuse/tzsw.HardKernel of=/dev/mmcblk0 seek=2111
