Booting (/boot) rockpi-4c (armbian,20.08.1,focal,5.8.6) from emmc (or sdcard) with '/' (root) on nvme.

[spherulite]

Current Hardware Setup: Rockpi 4C,eMMC module,eMMC to SD Card Adapter, M.2 Extension Board, NVME Drive, USB To Serial Debug Cable.

 

OS: Armbian_20.08.1_Rockpi-4b_focal_current_5.8.6.img.xz

 

(Right now, I'm using the above mentioned os from sdcard and the os can detect nvme disk using 'lsblk' command)

 

Query: How one can install '/boot' partition on eMMC (or sdcard) and '/' (root-partition) on NVME disk (attached to rockpi 4c through M.2 Extension Board) ?

 

(aim is to boot from either eMMC or ssd and use nvme disk as / partition)

 

Waiting for your valuable suggestions.

Thanks in advance from,
Spherulite.
