Hi Wolfgang,
[quote user="Wolfgang"]("DSP/BIOS supports stopmode (which you've used). To get the data off without halting the processor, you can try to use RTDX. However, TI no longer officially supports this interface.")[/quote]
This is accurate. CCSv5 no longer support real-time updates of the RTA tools like you had in CCSv3.3. Part of the reason is that RTA real-time updates relied on RTDX has the underlying transport and as already mentioned, RTDX is no longer supported.
[quote user="Wolfgang"]1.) Is it correct that there is no possibility to get a printf-output while the DSP is running (CCS5/DSP-BIOS) ?[/quote]
yes
[quote user="Wolfgang"]2.) Hence is it correct that there is no way to get Feedback from the DSP while it is running in my case (TMS320C6414T) ?[/quote]
there is no out of the box solution available for you via CCSv5&DSP/BIOS. DSP/BIOS is being deprecated in support and the newer SYS/BIOS is focusing on newer devices.
Sorry
