Use PCIe X1 for M.2 NVMe SSD

[x10]

Hi, All

Is it possible to use the mini PCIe in iMX7D SABRD to connect an M.2 nvme ssd, with an adapter of course? The M.2 nvme module can be either PCIe X2 key B+M, or PCIe X4 key M. As my understanding, PCIe X1 should be work with these modules with lower speed which is fine enough in embedded applications.

Thanks for help in advance.

Hi Cheng 

yes, since i.MX7D has PCI Express port (PCIe) v. 2.1 with one lane

seems there should be no problems for using that device.

I tried different M.2 SSD on Sabre board with mini-PCIE to M.2 adaptor.

- Kingston A1000 - can be detected and work normal.

- Western Digital SN520 - can't be detected

- Foresee P900F128G - can't be detected.

Please advise what's wrong!

KINGSpec M2 128GB NVME

MZ - FLW1280

Above three typies of NVMe modules are worked with my customer iMX7D board.

Which mini-PCIE to M.2 adapter have you used? Could you please send me a product link of this adapter?

Thank you very much.
