Re: working with AD-FMCOMMS1 at low sampling rate

Hi Lars,

 

I've tried building new .bit file with 128bit width on src side between DMAC and PS7 (AXI_interconnect 3) as you suggested.

Changing only "DMA data source bus width" from 64 to 128 on DMAC1, was not enough and caused to an error in building the netlist. Then I tried changing the AXI-interconnect3 data width to 128 as well:

and after that I was able to make the .bit file without any problem.

However, running that image on SDK, I could not connect to arm, getting the error:

Could not power-up the DAP <CTRL_STAT=0x0>. Am I missing something?


I checked C_S_AXI_HP3_DATA_WIDTH on PS7 and it was 64bits and I couldn't change it to 128:

Is it the limiting problem? If so, is there any way to overcome or work around?

 

Best Regards,

FArid
