Error while creating a new partition and mounting it

[goldshakil]

Hello,
I have connected the Cosmos+ board through PCIe Adapter to a host PC and after running the given code the host PC recognizes the device correctly in " lspci" command and it shows:

Non-Volatile memory controller: Xilinix Corporation Device 7028.

However, when checking the /dev directory there is no nvme device.

Are there any solutions?
Thank you so much and regards.
