DStream does not recognize Zedboard

Former Member

Hi,

I would like to use arm ds5 tools to debug my zedboard.

I followed tutorials on this website (http://zedboard.org/reference-designs-categories/debugging-arm-processor-systems-using-arm-ds-5) to try configuring DS-5 for ZED.

So I made hardware connection as indicated in the tutorial one, that is to say connect the ribbon cable and set the jumper correctly. Then the Debug Hardware Configuration of ARM DS5 is not able to autoconfigure my device (tutorial 2), and I get the following message :
"Auto configure failed. Check the debug Hardware connection with the target or try using a lower fixed frequency."

However I am able to recognize the device with a jtag probe from xilinx and with the Vivado Hardware Manager.

Any idea of my problem with my dstream ?

    Hi Calimero,

    Yes, we have demonstrated that a connection can be established with ZedBoard using cascaded JTAG under ARM DS-5 version 5.14 when we developed this training.  I believe that version of DS-5 tools required a connection to be setup manually and this is covered in Lab 2 of our hands-on training.

    Also, this connection setup process is covered in this ARM blog post here:

    https://community.arm.com/groups/tools/blog/2013/11/01/new-platform-bring-up-with-ds-5

    ARM DS-5 versions 5.15 and later were supposed to have built in connection definitions for ZedBoard.  I think we tested this in version 5.15 but perhaps not in the subsequent versions.

    I don't have a good explanation as to why the ARM DAP is not automatically connected on earlier versions when using a standard Cortex-A9 connection.  My best explanation, and possibly incorrect, is that the ARM DAP appears first on the chain but the PL PCAP appears second which confuses the DS-5 tools standard Cortex-A9 connection configurations.

    I see you routed the PJTAG interface out to the FMC card.  Alternatively, you can split the JTAG chain and route the PJTAG interface to Pmod JE1 and use the 6-pin side connector on Processor Debug Adapter (AES-ZBDB-ADPT-G) to connect DSTREAM directly to the DAP that way.  You will still need to load a PS configuration (to set the MIO) but you will not need to use the FMC or load a PL to achieve that connection to the ARM DAP.
