I'm trying to debug some of my code. I have dsplink built with debug. I think I have cmem built with debug (although I don't see all the messages that I'm expecting, so that may not work the way I think it does.) CE_DEBUG=2.
As you can see in the output below, I see failures in cmemk. I'd like to figure out what causes those. (0x7cee7 is indeed in the cmem areas of memory, although I'm not sure how cmem works, so I'm not sure how they got there or what that means). Here's the concern. The cmem call is failing to get the physical address, but I get no indication that the call failed. That is, I still get a 0x40023000 (instead of a NULL) returned from Memory_contigAlloc. If the call failed, shouldn't I get an indication back? What if this happens in my application. Is there some way for me to tell that the allocation failed?
Also, if anyone has seen 7cee7 before, please let me know what the context was/is. Thanks.
