Looks like this. See the last couple of posts; since the sdk is nearly here it should be being looked at soon.

I run some more tests and it does look like a similar problem. I will investigate this a bit more. Thanks a lot!

EDIT: Just in case someone runs into the same problem, here is what I found:

1. Reading/writing too much data from the SHDRAM too quickly seems to cause a problem, even without DMA
2. If and only if the program is stored in the SRAM, then it works most of the time. Otherwise, it freezes/crashes.
