Installing Ubuntu 21.04 on the HiFive Unmatched

Hi jawn-smith, thank you so much for this guide!

I followed the steps and I was able to boot Ubuntu 21.04 on my SiFive Unmatched from the nvme!

However, I have a couple of questions:

  1. the rootfs is loaded from the nvme, but the boot partition is still loaded from the sdcard (see foto attached). Is it normal?

  2. The SiFive Unmatched still requires the sdcard for loading the u-boot at startup. Is it possible to install to install the u-boot in a way that the sd card is not needed anymore (e.g., changing the dip switch also) ?

Thank you again!
