How to use printf() to print string to UART in KDS3.0 + KSDK1.3

[#1]

This document includes two chapters , chapter 1 is about how to use printf() to print string in KSDK1.3 project ,

the usage in project without MQX has been introduced on another document,

you can find it here : https://community.freescale.com/docs/DOC-104349 ,

so in this DOC I only introduce how to use the printf() in KSDK MQX- Lite and KSDK MQX-Standard project .

Chapter 2 introduces how to check which UART port is used when use printf() to print string on the FRDM board and TOWER board .

In sum, only the project of “MQX standard” use it own driver for printf(), so we need delete the driver “fsl_debug_console”.

In other SDK+PE projects , they all use the driver of “fsl_debug_console” for printf().
