is there an easy and convenient way of updating rootfs

[yakabmarci]

i mean do the update somehow on the fly without removing the card from a running system, on the pc build a new rootfs and instead of removing the card, and do the copying on the pc, do this directly on the dk board. in principle it should be possible, i just need the 'magic' commands/scripts, or even have this new rootfs in ram on some ram drive

e.g. scp the new rootfs, then chroot to it, somehow

Hi @yakabmarci​ 

By connecting your board with ethernet you can update rootfs via "scp",then "sync" command to write it to SD-Card.

You have also solution to use remote rootfs via nfs or tftp server.
