Hello DImaA,
It totally depends on the Interfacing technicque you have followed.
You cannnot simply swipe the Data lines.
You need to cunsult your Hardware Design Engineer to see the Impact on design when you swipe.
IF you are using DDR which is interfaced with only one Microcontroller
- IF you swipe D0 with D15
D0--> D15
D15--> D0
- While reading also you will read in the same fashion from DDR.
D15-->D0
D0-->D15
- I dont see any issue in this fashion because when you recive the DATA again you will receive the correct DATA.
It depends on the way you have interfaced the whole design, if you can post the Circuit diagram will help us to comment.
Probably it wold not work due to data mask signals. D[0] is lower byte and [D12] is upper byte. System will crash on byte accesses. But is very likely swap between D[2] and D[5] not to affect system work. In general data lines swapping is not recommended nor practiced in commercial systems AFAIK.
