bossac.exe: extra arguments found

After installing the new Arduino SAM Boards Version 1.6.8 today, I am not able to program the DUE.

C:\Users\xxx\AppData\Local\Arduino15\packages\arduino\tools\bossac\1.6.1-arduino/bossac.exe -i -d --port=COM3 -U false -e -w true -b C:\Users\xxx\AppData\Local\Temp\build9e6a761cfa8ee8f109724a87a40faf42.tmp/motor.ino.bin -R
bossac.exe: extra arguments found
Try ‘bossac.exe -h’ or ‘bossac.exe --help’ for more information

This is because the argument true behind -w is wrong. The following line works:

bossac.exe -i -d --port=COM3 -U false -e -w -b C:\Users\xxx\AppData\Local\Temp\build9e6a761cfa8ee8f109724a87a40faf42.tmp/motor.ino.bin -R

I think this must be fixed in the package.

I get the same error :frowning:

Pressing "Reset" on my Due doesn't do anything.

Everything worked until 3PM today, it is now 9PM.

Bit of a newbie, so where do we go from here?

I have one non-functional Due :frowning:

There was an update, earlier, to "avr" and "sam"????

You can install the old version. Go to menue Tools->Board->Boardmanagement??? (the top most item).
In German: Werkzeuge->Board->Boardverwalter

Click on Arduino SAM board and select version 1.6.7
Install this and in my case allworks like before the update

SAM Core 1.6.8 Not compatible with IDE 1.6.8!!

Hey all,

To avoid anybody else having the problems CactusCody98 and I just experienced in THIS thread, the update to V1.6.8 of the SAM core is not compatible with IDE V1.6.8!

The Nightly build of the IDE V1.6.9 Hourly Build 2016/05/06 05.33 works fine with SAM Core 1.6.8, but if you are using IDE V1.6.8, you need SAM Core V1.6.7!!



I updated to 1.6.9 and all is good again.... :smiley:

The update to 1.6.9 solved the problem. Thanks.

It seems this problem is beginning again in SAM-boards1.6.9 and Arduino 1.6.13.

The problem disappeared after downgrading SAM-boards to 1.6.7.
