How to add lib_apptrace.a to project (ESP32)

[vahidajalluian]

I am using vscode, Platformio and arduino platform for programming. Now what I am looking for is how can I use Application tracing library to output the logs to Jtag.
Here is the code

Code: Select all

#include <Arduino.h>
#include "esp_log.h"
#include "esp_app_trace.h"
void setup() {
esp_apptrace_init();
}

void loop() {
}
when I compile in vscode, the error log would be:

Code: Select all

The pre-compiled libraries for arduino do not include apptrace. You would need to compile your own with the CONFIG_APPTRACE_ENABLE option enabled using lib-builder.
