Leonardo upload still having problems (but is already much better)

[MAWMN]

Hello,
here is the Leonardo guy again, with more information. With the nightly build the upload is already going much better, but 2 out of 10 times still going wrong.

This is the error I receive:
java.lang.NullPointerException

And this is a copy of the console at that moment:

Having a look at the command for AVR dude:
Eclipse IDE:

Arduino IDE
E:\Tools\Electronica\arduino-1.6.11\hardware\tools\avr/bin/avrdude -CE:\Tools\Electronica\arduino-1.6.11\hardware\tools\avr/etc/avrdude.conf -v -patmega32u4 -cavr109 -PCOM9 -b57600 -D -Uflash:w:C:\Users\Marcel\AppData\Local\Temp\build0cd86ac184092c3731ad72037cfae4f0.tmp/Blink.ino.hex:i

==> Look at the part that says avrdude.conf -v -patmega32u4 of the Arduino IDE..

I think this is where the problem is...

The Eclipse IDE (or AVRDUDE) seems to be too fast or soon trying to send the data to the Arduino (COM9 not attached yet)....
(See also the ERROR reported : Forcing reset using 1200bps open/close on portCOM10
PORTS { CNCA0, CNCB0, COM1, COM7, COM8, COM10, COM25,} / { config error:, see https://github.com/jantje/arduino-eclipse-plugin/issues/252,} => { config error:, see https://github.com/jantje/arduino-eclipse-plugin/issues/252,}
Comport reset took250ms )

Probably the Arduino IDE gets just a little bit time to have the PC Switched and Attached the COM9 again, probably because of this -v (Verbose) output..

Hope this helps to improve further..

kind regards,

Marcel

The problem for avrdude is caused by
Using comportconfig error: from now onwards
Which you also see in the avrdude command as
-Pconfig
The problem is caused by jssc when asked the list of com ports.
This was reported in #252. In those days we got a uncaught exception. So for #252 I catch the exception and report this is the exception additionally caught in #255. (fortunately as I already forgot)
Only 2 people reported this issue so something "special" (read on your system) is at play here.
I do not have this issue here (I just made a upload test board containing a leonardo and it never happened).

[MAWMN]

Hello,

I have already solved the problem myself as I suggested above by adding the extra verbose (-v) parameter.
The score is now 0 errors out of 10 tries, and this over and over again.. ;-)

This is what I have done:

However what I have seen is when I create a new project I have to change this parameter again for every single project I create.
Is there a solution to make this global ??

regards,

Marcel

[jantje]

The -v is for verbose uploading. It doesn't make sense to me that this fixes the problem. (I'm not saying it doesn't)
If it does it would mean the leonardo is in a different state after the upload that makes the next reset work "better"
Anyways: If it fixes the problem you can add the -v to the platform.txt. This will make it do so for all new/modified projects

[MAWMN]

Hello,

today added the -v to the platform.txt

Works like a charm...NO more errors because the COM port has not appeared yet..

The extra console output it creates now, probably slows down the application just a couple of milliseconds on my system, just enough to have the new COM port being available again..

I am closing the subject now..

Again thans for the support and info..

Marcel

[jantje]

Cool I'm happy there is a workaround.
Thx for the feedback

[jantje]

I reopen as a workaround is not a real fix. I fear I'll have to look at jssc for this and other issues

[jantje]

I just finished quite a bit of stuff in the upload area.
Could you give this a new test?
