Simultaneously Debugging two Cores in AMP mode

Debug agent: RealView ICE
IDE: DS-5

Hi,

I have a question regarding simultaneously debugging of two Cores in AMP by using RVI/DSTREAM.
Error which i am getting on connecting to target(second core) is:

Configuration already in use.

I really appreciate your suggestions.

Asif.

I've never done this on a Cortex-R7, but I have done on various multi-core Cortex-As. So I would have expected it to work.

What exact steps did you take?

What I would have expected you to do is creating two separate Target Configuration entries in DS-5, for the two different cores (but referencing the same Dstream).

I've re-created roughly what you described with the a Cortex-A15 based board I'm working with, see the attached image. Note, this attached to the two cores independently - it be a different procedure if you want a more SMP like experience.
