MCIMX8QXP-CPU PCIe with M.2 connector

Hello,

I would like to know if it is possible to connect this kind of PCIe adapter with M.2 connector on MCIMX8QXP-CPU board to use a PCIe board:

Hi Xaro,

In theory, just considering the hardware side, they should be compatible if the hardware specification is compliant. However, I’m afraid that i.MX8QX is still on preproduction and no additional information/support could be provided yet. For further assistance, please contact with your Sales / FAE.

Hope this will be useful for you.
Best regards!
/Carlos

Hi Xaro,

We are currently experimenting i.MX8XQXPMEK PCIe link using a very similar PCIe to M.2 adapter.

Our custom PCIe daughter board is successfully discovered under linux (enumeration and BAR configuration), see command "lspci -v".

However, we need PCIe support in uBoot, it seems it is not yet fully implemented and/or working currently. We are currently searching for this information, if anybody knows ?

Best regards,

Laurent
