iMX8M Mini EVKB PCIe Hot Plug Function

zhirongyang — Mon, 26 Apr 2021 07:10:52 GMT

We want to use iMX8M Mini EVKB(with NXP BSP) to verify the function of PCIe hot plug, we want the following information:

1. Has NXP EVKB verified PCIe hot plug function?

2. What equipment does NXP use for verification? Can NXP provide the type/model for us to duplicate at our side.

Hi Zhirong,

PCIe of i.MX8MM doesn't support Hot plug.

Have a nice day!

Your mean doesn't support is hardware doesn't support or BSP doesn't support?

Hi zhirong,

Neither the BSP nor the hardware supports hot plug.

Have a nice day!

I am little confused, below topic says "yes hardware supports it, but BSPs have not software reference examples.", and the datasheet mentioned iMX8M Mini support PCIe 2.0, as a PCIe2.0 hardware it should support hot plug, could you please help to double confirm it.
