I tried the  FRDM -MCXN947 master slave I2C example  and setup the  jumper settings J2_20 , J2_18 ,J2_14 from the  both end  ,it is working  fine  .

For my requirement I need to change the salve pin configuration to j9_32 , j9_30 and j9_24 pins .and  accordingly i configured the  slave pins too .

But I'm not able to transfer the data . Showing  NACK in master .
Do i need to change any configuration ? 
Could you please someone help me  with that . ?
Thanks  in advance .

Hi,Ramanju_BV

Sorry for the late reply.

P1_8,P1_9 is not an I2C peripheral pin, please change to another I2C pin.
