Debugging Arduino sketch with STM32 Nucleo in Eclipse .. works !

I wrote instructions on how to do it ages ago

I don’t know if this is an error because the path – at least to me – is wrong in elf. I have a hard time to believe this would be a bug in GDB? No wonder Eclipse gets upset.

I still wonder where does “C:\Program Files (x86)\Arduino” come from.

If I command:
(gdb) break loop()
Breakpoint 1 at 0x5ee: file Blink3.ino, line 247.

You can open the cpp from the temporary directory

e.g. it adds this to the top of a blink sketch called GD32_test.ino

#line 1 "GD32_test.ino"
#include "Arduino.h"
void setup();
void loop();
#line 1

Is there any chance to modify the Arduino build process a little ?

I’d like to modify this:

#line 1 “GD32_test.ino”

into hardcoded path e.g.

#line 1 “C:\users\me\My Documents\Arduino\…\GD32_test.ino”

The only place you could look to see if there is any slashes in the wrong direction is the platform.txt file.

its

Arduino\hardware\Arduino_STM32\GD32F1\platform.txt

However I took a quick look and I can’t see anyhing in there that looks like it would be doing what you’ve seen

Your best option is probably to post an issue to github.com/Arduino/Arduino

https://github.com/arduino/Arduino/tree/master/

I could try to hack something in first when I get a little bit of more time.

Looks like Sketch.java is the file to modify

EDIT: I was able to modify the .elf. I changed string Blinky.ino into c:\kky.ino (make sure you only overwrite)

‘info sources’ shows now this.

C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino\hooks.c, C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino\main.cpp,
C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino\wiring_digital.c,
C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino\wiring.c, c:\kky.ino,
D:\Users\lainemi\AppData\Local\Temp\build321087032653580089.tmp\Blinky.cpp

Let’s see what Eclipse says about that Before that I have to copy original Blinky.ino –> c:\kky.ino.

Let’s see what Eclipse says about that Before that I have to copy original Blinky.ino –> c:\kky.ino.

Do you mean it doesnt find that file, or is there some other error?

.ino file in .elf –> not good. Have to get rid of that.

myblink.ino file contains only this line:

#include “C:\Program Files (x86)\Arduino\examples\01.Basics\myblink\myblink2.cpp”

myblink2.cpp:

#include <arduino.h>
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
Serial.begin(9600);
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
delay(100); // wait for a second
digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
delay(100); // wait for a second
Serial.println(2);
}

OK, this is pretty darn cool… Looks like I will have to try and recreate this stew… always something to pimp my time

Thats fantastic news

Would it be possible for you to write some step by step instructions on how to do this.

Including which Eclipse to install etc

Yeah, I’m happy to do that and save someone else’s time trying to do the same ! For some parts I’ll just refer to a great site which I found when investigating this. My order of Maple Mini’s and external ST-Link USB dongles are on their way so when they arrive I’ll try debugging with them also.

Now that debugging is working it’s time to start porting my Arduino Nano project for Nucleo and Maple Mini I posted an issue about this “.ino” to Arduino github – so let’s see what they think about that.

So for now getting .ino file opened in debugger remains as a mystery. When I have time I’ll try to do the same in Linux (or Linux in VirtualBox) just to see if the same problem exists there.
