I don't think the answer to this question is in "http://www.cypress.com/?app=forum&id=167&rID=68090". I have this same problem and I did what it says in the 68090 post and it did not solve the problem. I am using the SDK V1.2 and when I attempt to setup a Multi Channel DMA with size of 1024 and count of 16 I get a MEMORY error. This has nothing to do with cacheing but something to do with memory allocation. Does anyone have any help for this issue?
