ZCU102 - ARM-A53 and R5 not visible on JTAG Chain

When connecting through xsdb using the Digilent cable the ARM cores are not visible to the debugger.

Is there special setup or DIP switch that needs to be set for this to work.

xsdb% connect

tcfchan#2

xsdb% targets

  1  PS TAP

     2  PMU

        3  MicroBlaze PMU (Running)

     4  PL

  5* DAP (DEVICEEN is '0')

xsdb%

 

Thanks in advance

s,

 

Which release of Vivado are you using?  I beliueve it must be 2016.1 or later.

Yes Austin,

That is correct, I am actually using the "HEAD" build 2016.3  , if you have a patch I can request my

technical contact to send me an updated build.

clear register value @0xff180068

/sbin/devmem 0xff180068 32 0

then start xsdk 

seems to be working for now
