Dear all, I am presently working on TMS320C6416 board for some video encoding purpose. I am encountering a peculiar problem. Whenever I run a video of bigger resolution, after encoding say a few hundred frames, the CCS leaves a message "Trouble running Target CPU: Unrecoverable Emulation Error" and halts execution of the program. This problem is not recurring and happens only occasionally. I have tested the same code with simulator and it is not yielding any problem. I have checked for possible memory leaks in the code and there aren't any. Is there any memory leak due to CCS ? Have anyone else encountered the same problem.If so kindly help. What are the reasons for this error and any remedies ? Thanks in advance. Ganesh *********************************** Ganesh Vijayan DSP Desgin Engineer - Video Emuzed India (P) Ltd.

Some of the several reasons for your problem. 1. Cache incoherrency because of which you might be using invalid data. 2. Not properly restoring CSR value in one of your assembly kernels. 3. Stack overflow leading you into an invalid section of memory. 4. In case you are performing DMAs, make sure you wait for their completion and also make sure that cache coherency is ensured for source and destination buffer before and after completion of transfer. You will not see any of this problems if you replace your DMAs with memcpy and run the code on fast simulator Hope this helps. Regards, Anurag.
