Hi,

The shell and chprintf() can be used on any object implementing a stream interface, the UART driver does not implement such interface, you need to use the serial driver for this.

There is no specific documentation, you can generate it using doxygen on source files but it is exactly what you can see in the source comments.

There are lots of examples in demos and test applications.
