Configure and run the GNU profiler.

Syntax

profile [options]

Configure and run the GNU profiler. Profiling must be enabled while building the 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, because 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 a 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.

Examples

profile -freq 10000 -scratchaddr 0

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.
