Hi all,
1,For AM644x DDR4 hardware design, it used 39.2ohm, how to decide the value, can you provide some documents for this consider?
2,Why used OSPI0_CSN1 to control DDR_VTT_EN, what's the propose of this design?
3, For below design does it need the capacity place near the resistance?
thanks!
BR,
Denny
