If I type (icache on) the syst= em locks up. Anyone know if this symptom is telling me something I need to = look at such a layout other variables ect.

We are execut= ing code in Flash and have written a DDR-ram test walking ones and walking = zeros and address and address this will run for days at a time billions and= billions of writes and reads. When we move this to DDR-ram which is a MICRON MT47H64M8CF-3:F which we use= two of on SD-16 through SD-31with SD_A0-SD_A13 and SD_CS SD_DM2 SD_DQS2 SD_DM3 SD_DMQS3 We cannot run code we are using the same settings as the Reference design t= he same chips. I have layed out the board with mentor and have put restrain= ts in all of the lines to keep them within .4 inches in length. The symptoms are it either gets an exception out in space or locks up befor= e it gets to NET: functions Anyone have any thoughts about the issue. Gregg [email protected] Send a post to the list.
