how can I redirect the printf() output port

[rituparnasaikia]

Can any one tell me how can I redirect the printf() output data in ARM processor to a different serial port. By default keil writes into Port 0. I want to do it dynamically.

Some C Library functions needs initialization for example the printf function. You have to search for the runtime C library initialization and change it. If not possible, and you are using linux, you can redirect the output and the error to a different consoles using the ouput and error redirection as in https://linuxhelp.blogspot.com/2006/01/inputoutput-redirection-made-simple-in.html#axzz0du03uyow.

I am using Keil uVision 3. I have done it a few years back but forgot how to do it .

Most of my development is using linux systems.
You need to consult your tool chain documentation and check how you can change C library runtime initialization.
