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

michael_l Sat Aug 29, 2015 7:17 pm

I have followed this site http://gnuarmeclipse.livius.net/blog/install/ to install GNU arm toolchain, build tools, etc. Compiling works okay, binary is created. I’m using toolchain: gcc-arm-none-eabi-4_9-2015q2-20150609-win32
Debugging does not work. I am quite new to STM32, OpenOCD etc so I might do something wrong.

Based on this log I’m asking what could be wrong ? LD1 flashes red/green and nothing happens after this. It seems to be sort of stuck.

Yes, I tried… but I’m getting a lot of compile errors, and it’s really clunkier than the modified IDE and a worse workflow. So I decided to ask (why make an effort when you can ask instead

) and see if I can find the modified IDE. I hope someone downloaded a copy and is open to share

BTW: Michael’s writeup is really good, I would suggest adding it to the SMT32duino wiki. I read all the wiki, and kept wondering how I could debug. Sure, people can find it by searching the forum, but if proven to work, Michael’s writeup deserves to be in the wiki, imho

Atollic seems promising, and even the free edition seems to support SWD. I’ll give it a try tomorrow, thanks for the pointer

Meanwhile, if anyone can find the modified IDE, please post a note here

the odd site and books i’ve looked in say to export from as truestudio from CubeMX if arm-gcc compiler is to be used.
some other actions are also needed, such as to how the files or libraries are copied or not.

To close the loop: I figured out how to use the rick of having an empty *.INO and use a *.CPP of the same name to hold the code. I kept getting a meaningless error “multiple definition” for every function. The trick is to:

create an empty *.ino with only an include to a *.h with the same name and a 2 added to the end (i.e. foo.ino, foo2.h, foo2.cpp). In that *.h file you need to “declare” the function that you will call from the *.ino

i.e. the foo.ino file will have:

#include “<full path>foo2.h”
void setup() {
// put your setup code here, to run once:
}

void loop() {
// put your main code here, to run repeatedly:
foomain();
}

foo2.h will have

void foomain(void); (or whatever parameters the function uses)

and foo2.cpp will contain your foomain() function plus anything else you need

At this point Michael’s instructions will allow you to use Eclipse+OpenOCD+STLink to debug your code in the device. I’m still struggling to wrap my head around Eclipse’s quirks and its debugger interface

out of curiosity i tried these files 1.6.5r5 andarduino_stm32 from 111215
so i created the files foo.ino, foo2.h & foo2.cpp as in attachment
well it compiles and didn’t stop after error was printed
this is for a maple mini
haven’t tried running it either:D

Found the modified ide zip. Please save and share this:

You’d need to speak to the Visual Mirco guys about this.

I know they have general support for ArduinoSTM32 but I have not investigated the debugging side of things

(Note. Visual Micro registered as a user on this forum, so you could PM them)

Tim, Mr. Visual Mico, is very good about responding.
He put extra effort into getting Teensy ARM M4 (Freescale) working as Arduino folks kept dorking with the boards.txt strategy.

I prefer to use ST’s CubeMX and HAL. Preference. Much broader support base in the HAL than Arduino-esque.
But I know many people are comfortable with Arduino concept.

upload and debugging (per thread title)?

debugging = SWD or JTAG.

After a long pause decided to try Arduino IDE 1.6.9 and latest Arduino_STM32 .zip package. It looks like Arduino IDE produces .elf binary with correct paths! So I just compiled a OLED sample project and started a debug session with Eclipse. I am using blue pill with St-Link V2 dongle. It worked just fine and I could even add ‘global’ expressions in Eclipse IDE. Just wanted to tell this if someone is trying so there’s no need to use modified Arduino IDE

Which OS are you using ?
