Are you also allowing for any cpu cache?
The DMA won't snoop the cache.

The system is left as default when added, so yes: Instruction cache = 4kbytes, Data cache = 2kbytes, data cache line size=32bytes.

Ok, so I've placed heap into onchip memory and it works now, I can see contents in the memory content editor. Contents a bit strange, I've not done any investigations on that.
I've found more interesting thing (->output log here<- (
http://www.codeupload.com/4059)).
I create random 32bit pattern data using rand()&0xFFFFFFFF. This creates correct random data as it is seen in log lines 6 to 70.
Now when I try to read the data, it is read the same for 4 times: lines 117-120, 121-124, 125-128 etc.
Why is this happening? Wrong memory address increase step?
