I would recommend bs=512 to keep the block sizes the same though not a huge
diff just seems to be happier for some reason and add status=progress if
you would like to monitor how it is doing. Seems the command you have
should work otherwise.
So, given the fdisk output,
Disk /dev/sdb: 111.8 GiB, 120034124288 bytes, 234441649 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: 0x0000c89d
Device Boot Start End Sectors Size Id Type
/dev/sdb1 2048 1026047 1024000 500M 83 Linux
/dev/sdb2 1026048 2074623 1048576 512M 82 Linux swap / Solaris
/dev/sdb3 2074624 6268927 4194304 2G 83 Linux
would
count=6268927
?
oh, and this way, I can lay the image down on any drive. Even a mSD
card (as that is the actual boot device, but the Cubie uboot (and
linksprite) can run almost completely from a sata drive).
thanks
