i.MX6ULL I2C1 Pin Muxing

[AndromedaBell]

I am using the Variscite VAR-SOM-6UL with a i.MX6ULL processor on the Concerto Board.

Due to some conflicting pads with the project I'm working on, I switching the pin mux from

MX6UL_PAD_CSI_PIXCLK__I2C1_SCL		0x4001b8b0
MX6UL_PAD_CSI_MCLK__I2C1_SDA		0x4001b8b0

to

MX6UL_PAD_UART4_TX_DATA__I2C1_SCL		0x4001b8b0
MX6UL_PAD_UART4_RX_DATA__I2C1_SDA		0x4001b8b0

This caused it to completely stop working, not being able to communicate to anything thru I2C1.

Is there something I am missing here?

Hi @AndromedaBell,

I hope you are doing well.

The Pad configuration for the I2C1 signal seems correct.
Please cross-check that UART4 pads are not muxed for any other signal in the device tree
and i2c1 node contains status = "okay".

Thanks & Regards,
