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

There seems to be some problem with the build itself. I flashed the outputted file with STM32 ST-Link utility and it does not seem to work. I’m using Blink example. So that needs to be fixed first.

Using OpenOCD 0.9.0 and flashing an image from Arduino STM32 build I was able to flash it to my nucleo board. And it works too! I would like to say thanks for all the guys who have worked to get Arduino IDE working with STM32. This means building in Eclipse does something wrong and the image does not work. To be honest this was a bit of a disappointment for me I was expecting it to work. In Eclipse have used correct Template (STM32F10x) but obviously something goes wrong in the building. On the other hand it might be possible to manually start debugging session: First build flash image (debug) in Arduino IDE and then use Eclipse as IDE. It does sound clumsy. I am looking for solution to get proper image build in Eclipse.

I have connected SB16 and SB50. So I’m thinking does Eclipse GNU ARM plugin not expect that. Maybe there is some build flag involved that needs to be changed. The build uses flag: -DHSE_VALUE=8000000 . I wonder if that is correct?

Here’s log from telnet connection to OpenOCD.

First start OpenOCD:

C:\Program Files (x86)\GNU ARM Eclipse\OpenOCD\0.9.0-201505190955\bin>openocd.exe -f ..\scripts\board\st_nucleo_f103rb.cfg

Here’s objdump from Arduino:

Ok, it works!

I just created a new project (STM32F10x C/C++ Project) and debugging started to work ! Something magical has happened

Now the next thing would be to try to get Arduino .ino files compiled so that debugging is possible.

Well, done!
Because this is more eclipse related than nucleo I would suggest to Roger to move it into the “IDE’s” section of this forum?

Yes, that’s a good idea. Belongs to IDE section. Thanks.

Since compiling Arduino .ino files in Eclipse seems to involve quite a lot of work I’ve thought to compile sketches in Arduino and debug in Eclipse. Does that sound reasonable ?

I already found the “intermediate” files that Arduino IDE creates but I didn’t find symbol file for use with GDB. Is there an easy way to enable creating that in Arduino?

EDIT: seems Arduino compilier already uses -g flag. Fair enough.

Ok. Looks like I got debugging a project that was originally compiled in Arduino IDE working in Eclipse under Win32 that is. Eclipse IDE is quite good for debugging IMHO.

Here’s a few shots. I have to play with this a bit more to see how good it is but looks promising. Next thing is to do some tricks to get for example core library sources into project path to enable breakpoints there (not necessarily needed). For example C:\Users\me\Documents\Arduino\hardware\Arduino_STM32\STM32F1\cores\maple\libmaple contains a lot of interesting stuff that I’d like to debug – mainly just for fun

Debugger works reliably but I’m having hard time to have Eclipse find the actual Arduino source file (.ino). It finds easily everything else that is in build.tmp folder created by Arduino

Currently I’m stuck at this:

ANy help is appreciated. The directory it is referring to seems a bit weird ?

I had the same issue when attempting to use DDD under cygwin .

However this was when compiling using the IDE i.e a Windows program and then running DDD, a unix program, inside a cygwin shell.

Its odd the Eclipse has this issue when you have not used any other programs in the build process.

One quick hack could be to process the file that contains these paths and replace the slash with the appropriate one. I think this is in the .elf file.

However when I tried to do this run running DDD, it read the back slashes as escape chars, so it still didn’t work. And I could not find an easy way to process the elf file to replace / with \\ and \ with \\, without breaking the structure of the .elf binary file.

However you may have more success if you just need to convert forward slashes to back slashes

Ummm.

From what I recall the Arduino IDE compiles a binary that is then converted to a bin.

Perhaps Eclipse does it a different way.

Ah.

I didn’t realise you are trying to do that.

We’ve already investigated something very similar.

There is something called the Eclipse CDT Standalone Debugger, which we were hoping to use, but I posted to the Eclipse forum, and they said the debugger doesnt work on Windows.
Actually I think someone else from this forum also posted to the Eclipse forum, and I know the Eclipse team, were investigating how to get it to work, but that was at least a month ago.

You may be better of posting to the Eclipse forum

Take a look at this thread, as I think some things you tried, may have already been tried by other people

OK

I had to log into their forum to find it

https://www.eclipse.org/forums/index.ph … th=1006944&

I hijacked an existing thread on the same subject, and also “Stuart” from this forum posted independently to the same thread.

The post to the thread mentions a patch

https://dev.eclipse.org/mhonarc/lists/c … 29420.html

However I’m not sure if that means you have to patch your Eclipse installation of whether its been merged into their core, in which case if you have a recent copy of Eclipse, perhaps its supposed to work now.

Thanks! I’ll read those threads. I’m using Eclipse IDE C/C++ with GNU Arm plugins and build tools. Downloaded from here http://www.eclipse.org/downloads/packag … opers/mars a few days ago.

Its possible Eclipse has a bug that they are not aware of.
