The PRINTF() macro in the “blinky” sample supports two types of debug interfaces: UART and RTT.
The developer can select the debug interface during the compilation process by setting
the macro OUTPUT_INTERFACE in project settings. If the macro is set to -1, tracing is disabled. This is the default behavior in all sample applications.
Add “OUTPUT_INTERFACE=0” to the project settings preprocessor to enable serial interface in the “blinky" application.
DIO#6, assigned to the push button on the RSL10 EVB, has to be disabled for the USB/UART serial interface to work properly on RLS10 EVBs. To work around this problem, disable the push button.
Example for disabling the push button: in app.h of the “blinky” project, redefine the BUTTON_DIO (#define BUTTON_DIO 4)
To view the messages, you can use any application which supports a serial terminal (minicom, puTTy, teraterm).
