Hello,

Is there any way to do profiling (checking what time is spent in which function) on the CC2650 with TI CCS ?

And how ?

Best Regards.

Hello Frederic,

There are two main options of profiling support in CCS for your device (CC2650).

The first is a simply way to count clock cycles:

The second is to use SWO Trace for statistical profiling.

Thanks

Hello Ki,

Thank you very much for the answer.

SWO looks close to what I need.

However the link explains that SWO is using the TDO pin to communicate with the XDS110.

Since I am using the TDO pin for I2C communication already, do you know if it is possible to use another pin than the TDO pin to get the SWO outputs ?

Regards.

Sorry, SWO Trace is dependent on the TDO pin. If it is already in use, you will not be able to use SWO trace.

Hi,

I saw that the SWV could be mapped to any pin in the CC13x0, CC26x0 SimpleLink™ Wireless MCU Technical Reference Manual (Rev. H) page 408 :

"The SWV can be mapped to DIO n by writing the corresponding port ID in the IOC:IOCFGn register (see Table 11-27) For more details, see Chapter 11)."

Would this help ?

Regards.

Not for SWO Trace in CCS. That feature requires use of the TDO pin. Sorry.
