I downloaded the image of nanopi R6s from the official website[https://www.armbian.com/nanopi-r6s/](https://www.armbian.com/nanopi-r6s/), but it failed to start no matter burning to sd card or emmc. I know a lot of people have this problem, like this page [https://forum.armbian.com/topic/27904-armbian-images-for-r6s-r6c/?do=findComment&comment=164029](https://forum.armbian.com/topic/27904-armbian-images-for-r6s-r6c/?do=findComment&comment=164029)
