CCS: CCS debugging- Functions level- back trace

Gokul,

Could you please let us know:

• What device you are using?
• What version of CCS you are using?
• What debug probe you are using?
• What host OS you are running on?

CCS has support for PC trace on some devices but I am not sure if that is what you are looking for.

If you just want to see what functions are calling a particular function you can do this:

If you are looking for the call stack, this is shown in the debug view when in a debug session:

John

Hi John,
Please find my comments below.
What device you are using? dra7xx
What version of CCS you are using? Code Composer Studio , Version: 7.1.0.00015
What debug probe you are using? USB Blackhawk
What host OS you are running on? Windows 7
target os : Sysbios

With regards,
Gokul

Gokul,

Were either of the items I listed what you were looking for?

dra7xx would also have trace as an option. With the Blackhawk debug probe you could make use of the embedded trace buffer. Are you looking to gather this information for the ARM or DSP?

This link has some information on using Trace on KeyStone and AM335x devices. The KeyStone information would be relevant if you are looking to trace on DSP and the AM335x would line up with how to do it on the ARM core.

Thanks John. We are using m4 core in J6 dra7xx.

To the best of my knowledge the M4 on J6 does not have ETM trace.
