Single stepping with ARM Realview Debug

Note: This was originally posted on 22nd September 2012 at http://forums.arm.com

Hi,

I am working on ARM Versatile Express Cortex A9x4 (Quad core) board. I am using RealView ICE and Realview Debugger. Application was built with command line tools from Mentor Graphics which utilizes Nucleus SMP kernel GNU tool chain. Current build configuration uses two cores only. I wanted to navigate through a critical step of source for individual core (one core should be stopped while stepping through the other is being performed). To accomplish this, I have disabled synchronization of step option in synchronization control (snapshot attached)

. The application runs successfully as long as no break-point is enabled. Whenever I enable a break point, the application halts there and does not perform single stepping. Even if I disable break-points later in that session , it still remains there unless and until I reset the cores and disconnect and re-connect them.

Can anyone suggest some solution?

I have gone through the documentation of Realview Debug. Unfortunately, it covers too little in multicore domain. If anyone has link to such any document, please share it with me.

Regards,

Ejaz
