AXI DMA stream width

Jump to solution

Hi,

I need to set the stream data width of the S2MM interface in the AXI-DMA IP. The parameter appears fixed at 32 bits but in

old versions if Vivado the width could be modified according to the block connected to the AXI-DMA IP.

In 2017.4 the data width remains always at 32 bits giving a mismatch critical warning. Is there any way to solve the problem

when the blocks to connect have different data size (ex. 8 or 16 bits )?

Regards,

GS

Try using an AXI-Stream Data Width converter on the 32 bit stream interface to the DMA
