LOG_printf "live" with DSP/BIOS and CCS5

Other Parts Discussed in Thread: TMS320C6414T

Hi,

 

I'm comming from CCS3.3 with a Project (C6414) giving simple "Status Messages" via LOG_printf to the CCS3.3.

(Not really live, but displayed with a reasonable delay in the "trace" window).

I converted the Project to CCS5 (5.3.0.00090, now using DSP/BIOS 5.42.0.07). As the LOG_printf - Outputs do not occur i searched this Forum:

http://e2e.ti.com/support/embedded/bios/f/355/t/238859.aspx

It finally tells that I should go for RTDX

("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.")

But I was not able to "activate" RTDX to achieve what I wanted.

Tell that CCS5 does not Support RTDX.

1.) Is it correct that there is no possibility to get a printf-output while the DSP is running (CCS5/DSP-BIOS) ?

Hence I wanted to do this with "System Analyzer" and found (spruh43d.pdf) that it requires SYS/BIOS.

Hence I wanted to Switch to SYS/BIOS and found (spraas7g.pdf) that

"SYS/BIOS 6 does not support all targets that were previously supported by DSP/BIOS 5. The

following targets are not supported by SYS/BIOS 6: C54x, C55x, C62x, C64x, and C67x."

2.) Hence is it correct that there is no way to get Feedback from the DSP while it is running in my case (TMS320C6414T) ?

Excuse that I ask this but I just can't believe my conclusion.

Regards, Wolfgang

    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.

    yes (at least via any built-in feature of CCSv5)

    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

    Hello Ki,

     

    Thanks for clarification.

    Unfavourable that I'm forced to use CCS5 due to Win7/64bit. Otherwise I would have stayed with CCS3.3 for this device.

    Hi Wolfgang,

    > Unfavourable that I'm forced to use CCS5 due to Win7/64bit. Otherwise I would have stayed with CCS3.3 for this device.

    If still relevant, CCS3.3 can just work under Win7/64bit. In opposite to GNU/Linux.
