Hi Support Team,
My customer would like to know about the design of the evaluation board: TMDXIDK574.
Also, he would like to confirm if this design is workable or not.
(1) UDM is connected to DGND, but according to the DDR manufacturer's datasheet,
UDM is connected to VDD via a resistor.
This pin is the bit that masks the Upper Data Byte, so if you set it high, it will be masked,
but if you set it low, it will still not be referenced.
(2) DQ8 to 15 are connected to DGND via 10kΩ. In cooperation with (1),
did you fix the data to 0 because it is not masked?
From DDR datasheet:
My customer needs to know your reply by May-31.
I know the deadline for answering is tight,
but I would appreciate it if you could just post a comment.
Best regards,
Kanae
