How to remove PCI interface for WiFi module on i.MX8MQ EVK

limlee · ‎05-06-2021

Dear All,

I would like to know how to remove the PCI interface for WiFi module installed by default on i.MX8MQ EVK.

Should I change some configurations for device tree file?

When lspci command is input, PCI information about the WiFi module basically installed is printed as follows.

Hi Lim

one can try to disable it in dts, change "&pcie" status to disabled

https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/boot/dts/freescale/imx8mq-evk.d...

Best regards
