Hello support!!
I use custom board based on AM5749.
For EMIF Tool I use 10 Microsoft Office.
I have a questions:
1.Where I can get information about what SYS_CLK1 Frequency which I neeed for EMIF Tool???
I see the main clock for the processor is derived from a 20-MHz crystal on EVM Board.
2.MT41K256M16TW-107:P It is my chip and it is 1866 like a chip which set on EVM Board but in datasheet we have information: Supports rates up to DDR3-1333
Like I understood we have something like devider and it is work on 666 Mhz. At the same time I understand that it cannot work faster than the bus speed.
Please explain me....
3. If we look at the datasheet we will see: The Table 7-3. Supported DDR3 Device Combinations. I can't understend if I have 4 chips, I should set in EMIF Tool section--> 1B)DDR Memory specification--> width 8? Am I right? Or its is table for each Emif??
4. In stock settings Density is set 4 Gb but in fact we have just 2 on EVM Board maybe it is gigabits?? Or some setings not right...
5.In stock settings we have: Speed Bin Data Rate 1600 but in fact we have 1866 memory on EVM board. For what we using settings for 1600??
6.When I try to set 1866 memory and Correct CAS it is give me permission to set no more 11. But in fact 1866 memory support CAS =13, CWL=9
7.Which should be Data Bus Wight Per EMIF ??
8.When I try to change the meaning SYS_CLK1 Frequency in EMIF Tool it change it for example on 20 January or 19 february.
BR,
Oleg
