Enabling LPI2C4 in IMX93EVK

Robbi — Thu, 27 Mar 2025 10:44:03 GMT

Hi team,

I'm working with i.mx93 EVK kit. I tried to connect external I2C based sensor to J1001 connector on EVK kit. Hence I modified dts files

GPIO_IO02_LPI2C4_SDA
GPIO_IO03_LPI2C4_SCL
are the ALT modes of GPIO2.

I created a node and
assigned pins. but in the board i2c3 is not populated i.e lpi2c4.

Please guide me at which step I need to modify.

Thanks

Robbi

Got it, I had done changes in tmp/work/arch/arm/boot but changes need to be done in tmp/work/arch/arm64/boot path dts file.

Thanks
