How to direct printf() to console or UART or other peripherals?

How do you change the peripheral that will receive the printf() calls?

I guess it defaulkts in CW to console, I would like it to be a UART.

Thanks!

Hello

- Which CPU are you targeting (HC08, HC12, Coldfire, ..)
- Which version of CodeWarrior are you using?

I also need to knw how to correctly redirect console IO in the tower bareboard application to the serial port. I know how to do it under MQX, but not under a non-MQX project.

I have the same question on codewarrior 8.8 for MPC8306 chip, I used project wizard to generate one project which puts out a message to the UART terminal on the MPC8306_SOM evaluation board, when I looked through the project, I saw it includes a library output file "UART2_8306_SOM.UC.a", but there is no ".h" file associated with it also when I am stepping through the project from .reset or __start, I didn't see it called any function to initilize the UART, but the board do put out message into the UART terminal.

I want to know how to change the baudrate and other setups such as re-direct printf function into another UART on my own board.
