Use Mictor-38 HPS JTAG on HPS IO-48 OOBE Daughter Card Stratix 10 SX Development Kit.

Hi,

I am trying to carry out HPS Cortex-A53 debugging via external JTAG debugger (Arm DSTREAM), however the debugger is not able to locate any devices on the JTAG chain when connected via the Mictor-38 JTAG connector.

At the moment by board is running a GSRD image from QSPI from https://releases.rocketboards.org/release/2019.10/gsrd/s10_gsrd/ghrd_1sx280lu2f50e2vg_hps.sof and the board successfully boots into U-Boot however JTAG connection fails.

I need help to understand if the FPGA design needs to be updated to make HPS JTAG visible to the Mictor-38 connector or is it something that is by default available and should work. Also what configuration for JTAG SW1 should I use here ?

Thanks.

    Hi SSB


    Happy New Year! Sorry for the late reply.


    Is there a special use case that require you to use an external JTAG? There is an internal JTAG in in the Stratix10SX Devkit that you could connect to using only a USB Cable. I would recommend to use the internal JTAG.


    Are you able to flash the DevKit using the Quartus Flash Programmer?


    Initially the HPS would not be showing in the JTAG Chain if it is not enabled.

    Could you try the steps to boot the board from QSPI with the steps below:

    https://www.rocketboards.org/foswiki/Documentation/Stratix10SoCGSRD#Booting_from_QSPI


    You would need to flash the "ghrd_1sx280lu2f50e2vg.hps.jic" and boot the board from QSPI.

    After that you would see the HPS appearing in the jtag scan.

    The SOF file that you are using is only temporary and not permanent, that could be the reason why you are not seeing the HPS.

    Hi,

    I was able to make the external JTAG working via Mictor 38 after enabling JTAG DAP on HPS Pins instead of SDM pins in the GHRD design.

    Hi SSB


    Glad that you manage to get it working.

    Could you share the DIP Switch setting that got it to work?

    I used the default switch settings, while SW2 set up for QSPI boot [1:4] = on, off, off, off.
