On starting debug session Action Breakpoint suddenly jumps to another string and error message occured.
Code
Select All
Breakpoint 2, loop () at D:\Arduino\Proj\ESP32\M5Stack\MAX30102\RD117_ARDUINO/RD117_ARDUINO.ino:119
119	    Serial.print(aun_red_buffer[i], DEC);

What do you click to start debugging?

What optimization setting have you got set/disabled?

Thanks, can you please email the RD117_ARDUINO\RD117_ARDUINO.cpp fro the temp build folder to the address in the yellow box.

The temp build folder can be seen when verbose output or "show build folder" is enabled.

Done.
One more strange thing:
There is no loop() function in function list

Generally, I tried to follow "Drawing Graphs Using @Plot Windows" article directions.
Finally I made separate test project, similar that in article:
Code (C++)
Select All
#define apin 35
#define DAC  25

void setup()
{
	Serial.begin(115200);
}
//{@Plot.MyWindow.Sensor sensorValue}
void loop()
{
	int sensorValue = analogRead(apin);
	float voltage = sensorValue*2.0;
	dacWrite(DAC, voltage);
}


and obtained the same results:
jumping to next line and 
-var-create: unable to create variable object

Definitely it related with debug mode. It works with serial debug and do not with hardware GDB.
I found maybe similar issue:

Hi,

I suspect that in GDB mode line numbers are confused because you have added an include for Arduino.h to your code. We will fix that bug in the next release, for now I suggest you remove the #include because it is not needed.

#include <Arduino.h>

Thanks

There is no #include <Arduino.h> in the test project. But  symptoms remains.

I have made some tests and the issue seems related to the tool chain or hardware you are using. We are not seeing the problem with any of our tests.

Please provide the info in the yellow box above so we can see what you are working with.
