Hi all,

I have one nano pi m4v2 board and I am following http://wiki.friendlyarm.com/wiki/index. ... et_Started

I am trying to learn uboot and kernel with buildroot. My problems are,
1. google drive buildroot works, but buildroot repo doesn't. Main problem is with boot.img.
2. Is there a quick way to flash SD card to do small experiments quickly, rather than using fusing.sh which takes a lot of time to dd the SD card. So how to flash,

boot.img
uboot.img
rootfs.img
kernel.img


one by one to already prepared SD card with buildroot google drive image using dd command?

Or is there a better way to avoid all this and boot from sd card?
