【Hardware】 M.2 PCI-e hard drive support

Posted at 7/23/2018 23:50:18      View:6025 | Replies:4        Print     [Copy Link] 1#
I'm trying to get an M.2 2242 PCI-e hard drive (Toshiba OCZ RC100) working on a Firefly 3399 (128 GB eMMC, 4 GB RAM).

I'm using the latest eMMC image (Firefly-RK3399-ubuntu16.04-20180416112819.img).

The device does not show up in /dev/, and lspci returns nothing.

I attempted forcing a pci express rescan, but get a permissions issue even with sudo:
  1. $sudo echo 1 > /sys/bus/pci_express/rescan
  2. bash: /sys/bus/pci_express/rescan: Permission denied
Copy the code

dmesg output (full log attached) from boot is attached, it appears the pci-e power supplies are not enabled perhaps?

I get the following error:
  1. [    0.916262] rockchip-pcie f8000000.pcie: PCIe link training gen1 timeout!
  2. [    0.916910] rockchip-pcie: probe of f8000000.pcie failed with error -110
Copy the code

I see the same error whether I have the card in the slot or not.

Has anyone else successfully used the M.2 slot?  Are there any known working M.2 PCI-e hard drives (or other devices) for the Firefly?

I have not tried the SATA board; I'm mostly interested in if anyone has gotten a direct PCI-E connection to a hard drive (or other device).  I'll try Android and see if that changes anything.

Thanks for the info, enrogued.

What was the Intel NVME board they suggested?  I didn't think Intel had any NVME drives in the correct form factor for the RK3399.
