How to collect data
On the PC you need to run the tool ip3kprof.exe. This is a windows executable but runs on linux through wine.
- cd to SDK directory
- ip3kprof.exe -a -ip:<target_board_ip_address>
Example 1
ip3kprof.exe -a -ip:192.168.0.1
Example 2
ip3kprof.exe -a -ip:192.168.0.1 -lib:openwrt/build_dir/ubicom32/busybox-1.14.1 -lib:openwrt/build_dir/toolchain-ubicom32_gcc4.4.0/uClibc-0.9.30.1/lib -lib:openwrt/target/linux/ubicom32/base-files/lib/modules
Even .ko files can be profiled by adding the path of the library with –lib: option.
How to Interpret data
The collected data can be saved in .txt and .prg format. These files can be opened by profiler without active connection to target and used for analyse at a later point of time. Note:Please reset the counters before you start collecting otherwise you might get averaged data.
