Assistance for HPS and MSGDMA IP for Agilex 7

[Balkesh]

Hi all,

I am new to working with HPS so I want some assistance regarding these and I am using Agilex 7 board:

1) Actually I am using HPS with MSGDMA IP so can we simulate the project in modelsim as the board is not available right now and if possible can you provide the steps for the above process as I am not finding any documentation related to the same

2) .c and .h file for MSGDMA IP how they are compiled in the project or utilized

3) I have download Intel SoCEDS and ARM DS i want to ask what is the main purpose of these tools for HPS 

4) I also following a project related to communication between HPS and MSGDMA using Cyclone V board in that there is one dts file as well i want to know what is the purpose of this file, like it is the file for HPS OS or it is also in modelsim simulation

Hi Balkesh,

For msgdma IP, you can refer to the below two design examples which may help:

Involves Nios processor only:

https://www.intel.com/content/www/us/en/design-example/790774/agilex-7-fpga-nios-v-m-processor-with-ddr-dma-and-ocm-design-example.html

Involves Nios processor and HPS:

ARM DS is meant for debugging purpose. SoC EDS is a discontinued product, which is no longer supported. Anyway the information can used as your reference:

You can refer to the link below for simulation related with Nios:

Thanks.

Hello @aikeu ,

thanks for your response, Actually I already have taken the reference from some of the document which is mentioned above but i'm still at the question that how hps will get the descriptor which i've written so that msgDMA perform transaction from AVST to AVMM.

Suppose some packet is comming in the streaming mode and now i want to store them in the memory, as we know memory have different interface i.e. AVMM now in order to store data msgDMA should convert them in AVMM but msgDMA can not perform that transaction without the descriptor. Therefore i've used hps to provide the descriptor information to msgDMA for which i've written the .c and .h file but i'm not able get the steps how should i give it to the hps so that it provide to msgDMA.

regards

Hi Balkesh,

I found this msgdma example using Cyclone V which may help for your reference:
