Hi,
I bought first unit for evaluation for my product and I’ve stuck with what suppose to work - NVME drive.
I have 128 GB Samsung PM9B1 drive which is not properly initialised/detected as nvme storage.
Device is detected on a bus (lspci -v):
01:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd Device a80b (rev 02) (prog-if 02 [NVM Express])

However lsblk doesn’t show drive:
lsblk

I did found similar thread for A7E:
Can I use kernel provided on that thread on my A5E to check if this helps.
