Hi,
Does iMX8MM support PCIe hot-plug? I saw some previous questions about iMX6 which had contradicting answers as it supports and not supports. Regarding iMX8 https://community.nxp.com/thread/494660 this shows as it does not support but RM shows the registers for hot plug. Could you pleaase help to clarify this since we are in a time crunch for a proposal. Thanks
Hi Raajesh
unfortunately hardware does not supports it.
Best regards

Hi Igor,
Thanks for the reply. There is no reference examples but the standard PCIe BSP has the feature enabled. Is my understanding correct.

Hi Raajesh
yes standard PCIe BSP is enabled, except PCIe hot-plug.

Hi Igor:
How can we verify the PCIe hotplug feature/support by using the NXP demo board (imx8mm-evk)?
Best regards.

I confirmed it with i.mx expert hardware team again.
So clarify it again.
Hardware: PCIe interface doesn't support Hot plug.
software: Not support Hot plug, too.
DON'T USE HOT PLUG feature of PCIe On i.MX8MM.
Up to now, PCIe interface of all imx processors(i.MX6/7/8) doesn't support Hot plug.
Have a nice day!
