HI,

In my new project based on RX62N + Renesas compiler I am trying to use debug console, which files I need to add for using function “vPrintString”?

Where did the vPrintString() come from (maybe the book examples?).

If you are using semi hosting then the C libraries need to be configured to route output to the debugger.&nbsp; If you are not using semi hosting then normally functions like printf() need a thin port layer to perform the actual character input and output (that part being very application dependent).

Regards.

Using the FreeRTOS Real Time Kernel - A Practical Guide , creating tasks example . 1 has vPrintString();  
What is “Semi hosting”??

Thanks for the help.

According to the text the messages should appear in the debug console of the IDE.&nbsp; That is semi-hosting, the output is shown on the host rather than via a peripheral on the target.

Are you using the configuration as described in the text?&nbsp; The HEW IDE with the E1 emulator?

Regards.

Hi,

I am using HEW IDE with E1 emulator, But when I add vPrintString() in code I am getting the following error.

L2310 (E) Undefined external symbol “\_vPrintString” referenced in “P:\Codes\Bewo\Bewo\Bewo\_Phase1\_FreeRTOS\_1112013\Bewo\_Phase1\_FreeRTOS\_1112013\Debug\Bewo\_Phase1\_FreeRTOS\_1112013.obj”

vPrintString() is part of the demo code that comes with the books, not part of FreeRTOS.&nbsp; It is defined in basic\_io.c, and just calls printf() wrapped in schedule disable/enable calls to ensure mutual exclusivity.

Regards.

I downloaded basic\_io.c and added it to project, which solved the issue, thanks for your help.
