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 ?

    Here are some news !

    First of all if I boot the Zedboard in independant jtag, then the dstream is able to see something (fpga) but just unable to identify it (seems normally).

    I connected the PJTAG of Zynq and route it on an FMC card. I boot the Zedboard in independant jtag, load the bitstream to make the pjtag available on the FMC card, then the DStream is able to recognize the processor !!!

    That's lead me to wonder : has someone really achieved to use dstream in cascaded jtag, using the Processor Debug Adapter (AES-ZBDB-ADPT-G) and the JTAG connector of the Zedboard (USB or 14-pin jtag connector) ?
