[Banana] How to shrink /boot partition after running nand-sata-install

[sgei]

Hi,

 

yesterday I moved my root partition to a 128GB SSD by running "nand-sata-install"

Everything works fine.

Now I got a SD-Card in my Banana Pi with one big partition:

 

fdisk -l

Disk /dev/sda: 128.0 GB, 128035676160 bytes
30 heads, 63 sectors/track, 132312 cylinders, total 250069680 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
Disk identifier: 0x93d6d043

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1            2048   250069679   125033816   83  Linux

Disk /dev/mmcblk0: 3965 MB, 3965190144 bytes
46 heads, 9 sectors/track, 18706 cylinders, total 7744512 sectors

What do I have to do to prepare a new SD-Card (256MB) and move the Boot-Partition to it?

 

In /media/mmc is my old /root, isn't it?

 

Thanks.
