DMA questions

Hi @redson,

I moved the question to a new topic.

I want to use the DMA to fill a FIFO buffer of commands to keep them contemporaneous with the data the commands are affecting. Is it possible to send these commands in one long 128-bit word? Or do I need to buffer the buffer and fill it 32 bits at a time?

Set the Stream Data Width to 128 in the DMA, this should be enough.

Also, I generated a bitstream and loaded everything up to the Jupyter server as usual, but ol.ip_dict doesn’t show the DMA cores at all, even though I can see them clearly in the .hwh file. Is there a step I’m missing? Did something not compile correctly in the bitstream generation?

Did you try resetting the cache?
