Newbee question:

Sorry guys for asking this simple question but I give up I can not find it I looked all over.

I am using TINI400 board and have compiled the hello.c file with printf(“Hello World”); in it without any errors.

I would like to customize the putchar file for my application.  The documentation says there is no putchar provided then I am confused how did it compile the printf(“Hello World”); without any errors.

There must be a file somewhere in the lib otherwise it would have given me an error.  So where is the putchar file?

Can anyone explain this to me and tell me where I can find it?

Any help in this matter is greatly appreciated.
