DS-5 connect fail when cortex-r5 is in lock-step mode

Dear All,

I am using DS-5 to debug Zynq UltraScale+ MPSoC.

Evevrything goes well, but when the Cortex-r5 is run in lock-step mode, DS-5 cannot be connected(Cannot connect to A53 or R5).

When the r5 is in splt mode or r5 is powerd off, DS-5 work well.
