For the driver of a Modular Scatter-Gather DMA I need the header file "modular_sgdma_dispatcher.h". How can I get it, or what is the correct way to use "alt_msgdma_open" ?

Hi el.ing,

many thanks for your reply. I have been using the entire toolchain (i.e. Quartus, bsp-editor, arm-ds5 builder, etc.) of generation 16.1, because I was led to believe that newer versions of the toolchain dont fully support cyclone V devices (notably in terms of the pre-loader and boot-loader generation ). I re-installed version16.1, but the header is still missing. According to the documentation the msgdma should be available on version 16.1.

Allow me to depict my goal using the msgdma (Memory-Mapped to Streaming)

An FPGA-Application is supposed to consume data from the msgdma-streaming source. Problem: On the HPS I cannot "dump" the data into the msgdma, since I cannot use the necessary functions (alt_msgdma_open,alt_msgdma_construct_standard_mm_to_st_descriptor, alt_msgdma_descriptor_sync_transfer) due the missing header file.

How can I use the msgdma for cyclone V devices? I would be very grateful for a further tip.

Thanks

Andreas
