 I am using two pins as show above as flexio i2c,

when configure in EB, below errors occur.

I2c hardware channel used is FLEXIO_0_CH_2_3. For SDA Channel Ref select CHANNEL_3 of the FLEXIO device

I2c hardware channel used is FLEXIO_0_CH_2_3. For SCL Channel Ref select CHANNEL_2 of the FLEXIO device.

In hardware design, acturally using CHANNEL_3 as SCL and CHANNEL_2 as SDA.

Is there restictions that "The SCL channel must always be the lower-numbered channel in the pair" in S32K312?

Hi

Please swap the pins in Flexio_I2c or Flexio_Mcl_Ip.
