Hello,

Can anybody please tell me how i can read the addresses from the memory in debug monitor mode without halting the processor? Or is it any other way to read the memory registers like selecting some other access port.? i would be very grateful if somebody could help Thank you

Likely depends on the debugger and tools being used.

If you connect a serial port you can have your own code periodically output internal state information. The is also the SWV (Serial Wire Viewer), you can use that to output putchar()/printf() information.

Thank you for your reply. I am working on a project to generate JTAG signals to read the memory registers.

So i am not using any external debugger. I need to write a code for non intrusive debugging. so can you please help me that

I was using debugger and JTAG Pod somewhat interchangeably. You're building a pod, and driving the scan-chain.

I believe such interactions are affected by the processor, and it's buses. As such I don't think they are entirely transparent.I'm afraid I can't commit resources to your project.
