Hi Nassa!

Bossac doesn't work?! It happened to me, too. Are you using a USB 3 port? This could be the problem.
To fix it, just program the Arduino by using a USB 2 port or, if you don't have it, through a USB 2.0 Hub!
Cheers

I tried to follow to tutorial. But I cant build the static library I think some includes are wrong but I cant find out wich.

I got the following error log (not the complete log just this is just a small part) when trying to build. I'm on osx maybe that got something to do with it

Code:

Hi Joppuh,

I do not think your problem is not OSX.
In my opinion, there are two possibilities :

Either you forgot one of the 3 defines :
__SAM3X8E__
USB_PID=0x003E
USBCON

Either you forgot an include path or one or more files are missing.

Warning, and include Defines Path must be set in the configuration C and C+ + (Tool Settings) :
ARM Sourcery Windows GCC C Compiler
and
ARM Sourcery Windows GCC C + + Compiler

Let me known please.

Nassa.

[Reply #18 on:]

These are my defined symbols in C and C++ compiler
_SAM3X8E_
USB_PID=0x003E
USBCON

These are my included paths

"${workspace_loc:/${ProjName}/src/core}"
"${workspace_loc:/${ProjName}/src/lib/CMSIS/Device/ATMEL}"
"${workspace_loc:/${ProjName}/src/lib/CMSIS/CMSIS/Include}"
"${workspace_loc:/${ProjName}/src/lib/libsam/include}"
"${workspace_loc:/${ProjName}/src/lib/libsam}"
"${workspace_loc:/${ProjName}/src/lib/CMSIS/Device/ATMEL/sam3xa/include}"
"${workspace_loc:/${ProjName}/src/lib/variants/arduino_due_x}"

[Reply #19 on:]

The processor Define is :
__SAM3X8E__
and not
_SAM3X8E_
There is 2 underscore before and 2 underscore after.

Could you verify ?

And let me know please.

Nassa.

[Reply #20 on:]

Still got 135 errors but all in USBcore.cpp

But Im able to build I got a libArduinoDueCore.a in my Release folder.

But I think the linker script isnt working for de MyProject
If I build your example I only get a main.o and a syscalls_sam3.o in my release folder..

EDIT
All the errors about USBcore.ccp are could not be resolved errors like:

Code:

Field 'UOTGHS_DEVCTRL' could not be resolved

[Reply #21 on:]

Clean your ArduinoDueCore project :
- clean ArduinoDueCore project
- in the "Problems" tab right click on the root errors node, when the popup is open, click on "Delete" item. You can do the same for warnings.
- bluid ArduinoDueCore.

Build MyProject.


Nassa.

[Reply #22 on:]

No more errors or warnings!

But nothing in the release folder of myprojects..

I'll try to make a new project

EDIT
Got a .map file in my release folder but not a hex..

[Reply #23 on:]

Hi Nassa ,
 I played a bit with arduino uno elipse integration and looking at your guide I don't see the define which says which board is beeng compiled.
In case of Aduino due it is -DARDUINO=151.

Hi Nassa,
 if I well understood ,to use the PROGRAMMING port with bossac you shall use one of the two procedures reported in the AduinoDue main page. that are :
1) pressing the erase button on the arduino while running bossac
2) Open the serial port without bossac, which activates the Erase and Reset sequence , and then launch the bossac .

Unfortunately I can only use the bossac via command line while pressing the erase button, if I do that using the eclipse external tool it doesn't works.
I'll do a script which opens the port ,closes it and then run the bossac.

By the way, to understand how the bossac is actually run by the arduino IDE , I substituted the original bossac with a simple shell script and run the upload procedure on the IDE.
Here the code :

Code:

echo $@ >/Applications/Arduino-due.app/Contents/Resources/Java/hardware/tools/bossac.arg
/Applications/Arduino-due.app/Contents/Resources/Java/hardware/tools/bossac.orig $@

I've got these error's now in myProject
These error's keep coming back I defined -L but it seems i't cant find the library or something if I build like 3 times in a row it completes but only shows the .o files

Code:

undefined reference to `digitalWrite' main.cpp /MyProject/src C/C++ Problem
undefined reference to `USBDevice' main.cpp /MyProject/src C/C++ Problem
undefined reference to `USBDevice_::attach()' main.cpp /MyProject/src C/C++ Problem
undefined reference to `pinMode' main.cpp /MyProject/src C/C++ Problem
undefined reference to `delay' main.cpp /MyProject/src C/C++ Problem
undefined reference to `init' main.cpp /MyProject/src C/C++ Problem

EDIT:

Fixed it now I got a elf file!

[Reply #26 on:]

I resolved the problem with bossac in Eclipse , for some reasons ,in my case , if as first parameter in the arguments list is placed --port=tty.usbmodemfd121 the command ends with :

Code:

No device found on tty.usbmodemfd121

also when I press the erase button.
if --port is used as seconds parameter, using the erase button, eclipse and bossac run like a charm.

Code:

Erase flash

I tried to open the programming port and then to launch bossac , but I have still the uploading problem.
For the moment it works fine with the erase button.

@joppuh123:
It seems your core library doesn't contain wiring_digital.c , do you have it in yours library files? it is contained inside variants/arduino_due_x

Cheers

[Reply #27 on:]

I do got a wiring_digital.c I have it in /src/core not in variants...

I got an elf file I was able to upload the elf file but the led doesn't blink...

Is it because I dont got the -DARDUINO=151 define.

Also the library does build but is was browsing the source file and an error poped up.

Code:

Field 'PIO_OSR' could not be resolved wiring_digital.c /ArduinoDueCore/src/core line 62 Semantic Error

Getting an stm32 working in eclipse is easier than this!

[Reply #28 on:]

HI All,
 finally I did it !
I'm able to build the blinky led program and upload it using the external tool all done in eclipse.
The last tiny problem is the bossac manually operation...
I've followed a different path from the one proposed by Nassa, obviously is due to him if I'm at this stage.
I will soon post how I did it .
 Cheers

Congrats I'm excited to hear how you did it!
