Configure and run the GNU profiler.

Syntax

profile [options]

Configure and run the GNU profiler. The profiling needs to enabled while building BSP and application to be profiled.

Options

Option Description
-freq <sampling-freq> Sampling frequency.
-scratchaddr <addr> Scratch memory for storing the profiling related data. It needs to be assigned carefully, as it should not overlap with the program sections.
-out <file-name> Name of the output file for writing the profiling data. This option also runs the profiler and collects the data. If file name is not specified, profiling data is written to gmon.out.

Returns

Depends on options used.

-scratchaddr, -freq: Returns nothing on successful configuration. Error string, in case of error.

-out: Returns nothing, and generates a file. Error string, in case of error.

Example(s)

Configure the profiler with a sampling frequency of 10000 and scratch memory at 0x0.

profile -out testgmon.out

Output the profile data in testgmon.out.
