if required: resize root partition
1. take a note of a starting sector of a partition to resize (on SD image on my Git it is 374784)
2. start fdisk on mmc card device /dev/<disk> (usually /dev/mmcblk0)
3. remove the partition and recreate a new, larger partition primary starting from sector 374784. and with desired new size
4. write new prtitions in fdisk with keeping partition signature. exit fdisk
5. resize filesystem to new part.size by resize2fs /dev/<part> (usually /dev/mmcblk0p2)
6. reboot
