Remote debug AFU on-chip memory using System Console.

Hi @khyam

I am not familiar with AFU and I believe the document guide here helps to provides some guidelines on how to remote debug AFU.

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/afu-developers-guide.pdf

  • System Console must be started after launching the mmlink application. If System Console returns an error, close the mmlink application, re-invoke mmlink, and launch System Console again.

Hello @RichardTanSY_Altera ,

I am able to launch and connect AFU through remote debug and I have done debugging of AFU using signal tap tool. Instead of signal tap, we can use the system console for FPGA memory debug using Avalon MM commands like master_write_32 and master_read_32. I tried using the system console tool for FPGA memory debugging, the claim command used for claiming the master service for operation(FPGA memory read/write). I got the below error for claiming master service.

error: claim_service: Could not claim service at /devices/1/(link)/TCP/sld_hub_controller_system_0_fabric.h2t_0/sld_hub/(110:132 v1 #0)/phy_0/master: Channel(s) have already been claimed, and the new claims are not compatible with the existing claims(s).

    Hi @khyam

    I am not sure what goes wrong... could you help to share your design (a simplified one .qar design file will do) that could duplicate this issue?

    May I know what OS and which device that you are using?

    Kindly help to provide the steps to duplicate the issue as well.

    I will need to further investigate on this.

    Best Regards,
