Connect External Arm DSTREAM Debugger and Arm Development Studio with Intel Stratix 10 SX DK

Hi all,

I have my Intel Stratix 10 SX Development Kit up and running with FPGA design programmed into SDM QSPI flash via USB-Blaster II cable. U-Boot does run on the Cortex-A53 core when board boots up and I am able to deploy and run my hello world application on top of U-Boot on the A53 core.

I am now interested to debug my application using external Arm DSTREAM JTAG debugger by connecting to the Cortex-A53 cores and debugging it via Arm Development Studio v2022.0 . At the moment Arm DS is unable to connect to the A53 cores and gives an error that a "Stratix 10 device has not been recognized". Can someone please guide me what switch settings should I use so the A53 cores are added to the scan chain ? Please find below my current switch settings:

SW1 [1-8]: off, off, on, on, on, on, on, on
SW2 [1-4]: on, off, off, off
SW3 [1-4]: off, off, off, off
SW4 [1-4]: on, off, off, on
SW8 [1-2]: off, off

Best Regards.

    Hi,

    Thanks for the response. The document you mentioned above does not point on how configure the FPGA image to include the HPS into the JTAG scan chain and carry out debug via external JTAG.

    Any help around that area is appreciated. At the moment, on launching a debug connection, ARM DS complains that the connected device is not recognized as a Stratix10 platform.

    Thanks.

    Hi Jingyang, Teh

    Thanks a lot for the response. Essentially it seem like that the HPS JTAG is not visible to the debugger at all. This is what the SPL and U-Boot prompt looks like :

    Do I need to deploy a different reference design to make HPS JTAG visible in the scan chain ? Any steps for configuring such a design ?

    Note that I am using HPS IO-48 Daughter card and using the Mictor 38 Pin connector for HPS JTAG access.
