    Hi Vishrav,

    If you are creating the Basic Example: Hello World example, the printf should come out on the console.

    If you are creating the DSP/BIOS v5.xx Example: Hello example, the Log_printf goes into an internal buffer. You can view the log data via the Tools->RTA->Raw Logs tool. The Log_printf is a smaller footprint and has better performance than printf.

    Regarding the multiple tasks, the TSK are statically created in the tsk.tcf file. You can modify this file via a text editor or via the DSP/BIOS Configuration Tool (right-click on the tsk.tcf file and it gives you both options). Statically creating the TSK helps keep the footprint small. Another option is to simply create the TSK dynamically (e.g. call TSK_create in main()).
