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.

  • Hi,

    Sorry to hear about this.

    Can you please confirm a couple of things here :

    - what version of DS-5/Arm DS is in use

    - are you using the ZCU102 or Ultra96 board or 'something else' ?

    - how are you booting the target board : from SDCard, flash, JTAG... ?

    - how are you configuring the R5's to be in lockstep mode, specifically what is the RPU_GLBL_CNTL set to, and when during the boot process ?

    If you don't want to discuss this publicly then please a support ticket at https://developer.arm.com/support

    regards,

    Stuart
