T1024 DDR

Hi,

During the DDR initialization software is setting D_INIT bit and after initialization is done software waits for this bit to be cleared. Hardware will clear this bit after the initialization is complete. Clearing of D_INIT bit is consistent for all T1024 hardware’s or it will changing with variation of environmental factor (temperature or electromagnetic effect) or any other factors?

The clearing of D_INIT bit is done 100% of time by HW if DDR initialization completes.

I accept what you said and we are seeing the clearing of D_INIT bit by hardware. Powerup to powerup will their be any variations (timing variations) in clearing this bit ? Will it be consistently clearing the bit?

For the same board type (same HW and SW/settings), the time it takes to clear the D_INIT would be constantly the same.
