UART0, UART1 and I2C0 utilization and Initialization

mexco

Hi, I need to use UART0, UART1 and I2C0 in my application. I initialized these in overlay file (attached). When, debug is run, it is observed that the I2C binding is not successful see attached image file. I am using UART0 and UART1 in asynchrounous mode.  The zypher.dts fie also is attached.

    Dear Hellesvik, you pointed through the links that TWIM and UARTE have same ID and address space. Therefore, how to do instantiaiton of such Peripherals ? Should instantiaiton be done in Kernel or Programitacally ? If say UART0 has been instantiated in Kernel, then how to disable it and enable I2C0 programitically ? After completiotion of I2C0 transmit/ receive task, how to enabke UART0 again ? I2C0 is to be used as TWIM.
