Enabling GNSS on iMX8 QM

swayamdhondge10 — Mon, 07 Jul 2025 09:41:34 GMT

I want to know how we can connect a GNSS receiver to the imx8 qm baord as it doesn't support in-built gnss module. Would appreciate if someone can guide me to a detailed document on this.

Also, how I can connect to a CAN signal generator.

don't find such specific solution for GNSS on imx8qm, you can refer to the can settings, then add by yourself

https://github.com/nxp-imx/linux-imx/blob/lf-6.12.y/arch/arm64/boot/dts/freescale/imx8qm-mek.dts

you also can refer to another customer who enable this with uart

Thanks for the reply.
Is there any plug and play module or chip available which can be plugged to the NXP iMX8 qm and used as a GNSS receiver.

no official suggestion module which can plug to the imx8qm directly, but imx8qm has M.2 port, if the GNSS module support M.2 connector, maybe you can try it, suggest that you can refer to the 8qm schematic firstly
