Clearfog PRO CN9130: can't recognize SATA NVMe M.2

OCTEON CN9130

Hi,
I can’t recognize SATA NVMe M.2 disk.

I added the module on U-boot defconfig:

  • CONFIG_NVME=y
  • CONFIG_NVME_PCI=y
Marvell>> nvme info
Marvell>> nvme scan
Marvell>> nvme
nvme - NVM Express sub-system

Usage:
nvme scan - scan NVMe devices
nvme detail - show details of current NVMe device
nvme info - show all available NVMe devices
nvme device [dev] - show or set current NVMe device
nvme part [dev] - print partition table of one or all NVMe devices
nvme read addr blk# cnt - read `cnt' blocks starting at block
     `blk#' to memory address `addr'
nvme write addr blk# cnt - write `cnt' blocks starting at block
     `blk#' from memory address `addr'

what should I do to see the sata disk M.2 NVMe connected to the ClearFog-Pro card?

the sata disk is NVMe M.2
Obviously if connected to other PCs it works correctly

Thanks for your help

The nvme commands in u-boot are only for PCIe NVMe devices. For SATA based m.2 SSDs you need to use the scsi commands.

Thanks Jnettlet,
although scsi is enabled by default in u-boot and finding the relative commands the disk is not detected.

no scsi devices available

Do I have to check some specific module in the u-boot defconfig?

It should just require CONFIG_AHCI_MVEBU and DM_SCSI should be selected automatically.

the first was enabled by default, the second I enabled:
CONFIG_DM_SCSI=y

but nothing, I added:

CONFIG_SCSI=y
CONFIG_SCSI_AHCI=y

but nothing, it is not recognized any further ideas?

in Linux i find this:

root@localhost:~# journalctl -k | grep -i scsi
Feb 13 17:29:03 localhost kernel: SCSI subsystem initialized
Feb 13 17:29:03 localhost kernel: Block layer SCSI generic (bsg) driver version 0.4 loaded (major 244)
Feb 13 17:29:03 localhost kernel: scsi host0: ahci
Feb 13 17:29:03 localhost kernel: scsi host1: ahci

Unfortunately I got the wrong product (PCIe NVMe M.2).

I tried with a new SATA M.2 SSD disk and it is correctly recognized with command:

scsi scan

thanks for the quick reply!
