I am having a problem initializing SDRAM. I am using a MCF5329 and two IS43R1632D DDR SDRAM chips. I am testing the board using a PEEDI BDM debugger. I've attached the peedi.cfg file that contains the initialization code. When I run the PEEDI memory test on a 1024 byte block, it fails several times and then starts passing. I can get it to do the same for a 2048 byte block, but I can't go any higher. Why would the test fail two or three times and then start working? What am I doing wrong with the initialization?
