HI,

  I am using Msgdma memory mapped to Stream (in AGILEX -f agfb014r24b2e2v )(MM2S) with extended descriptor when i write the Descriptor and trigger the Dma data is streaming from the address of MSB  (0x0 offset ) 

for example :

I am write some dummy data in address 0x1160000000 
in 0x0 offset writing 0x60000000 

in 0x14 offset writing 0x11

and triggering the dma but when i check in sys tap analyser data is streaming which is present in 

0x60000000 only and ignoring msb
