# How to profile ardupilot binary on ESP32 and use result to place critical functions to the IRAM
|
|
## Prepare source
|
|
1. Configure project with `--enable-profile` option: `./waf configure --board=esp32diy --enable-profile`
|
|
2. Rebuild binaries
|
|
## Run program with profiling enabled
|
|
1. Flash and run binary
|
|
2. Try to use mode silimiar to real flight. I.E. compass/gps connected, armed state, and so no
|
|
3. It will write profile stat to the `/APM/APM/PROF000.TXT` files on the sdcard every one minute
|
|
## Use profile info to optimize program
|
|
1. Copy `PROF*.TXT` file from sd card
|
|
2. Copy file `arducopter.map` from build directory
|
|
2. Use them to produce `functions.list` by the script `LinkerScriptGenerator.kt` (modify paths and limits inside)
|
|
3. Place file `functions.list` to the `target/copter/main` folder
|
