20 years ago --- Quote Start --- originally posted by jdhar@Apr 11 2006, 02:04 AM sounds like you have hardware issues. if you have sdram and flash on the same bus (which is a bad idea imo), the sdram bus will be more heavily loaded, meaning you should test it for stability first.
- you should run the sdram at full speed with a hardware core to verify for errors
- have you downloaded just to sdram and run from ram instead of flash?
- if you can, disable or remove the flash chip and just run from sdram. this should help you narrow down the problem.
