Code uploading on DUE is not working in UBUNTU

[Atirma]

Hi,
We're facing exactly the problem declared in this link.
http://askubuntu.com/questions/681555/ubuntu-14-04-arduino-due-upload-firmware-issue
This problem is serious as it renders the DUE board useless under UBUNTU.

[NicoHood]

Why dont you switch to the 16u2 usb port?

[ffissore]

@Fede85 is having the same issue with his ubuntu 14.04, while I'm not with mine. My only guess so far it's that it's hardware related. Can you spare a 14.04 on a different pc and retest?

[Atirma]

Hi ffissore,
We have tested these issues on two PCs. Luckily, one exhibits this problem, the other doesn't.
Using command 'lsb_release --all' we obtain the following with PC that is able of uploading to the DUE:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Codename: trusty

Executing the same command with the PC where bossac fails, we get:

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty

Main difference is that the first one is Ubuntu 14.04.1 LTS while the second one is Ubuntu 14.04.3 LTS

'uname -a' returns:

3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux for Ubuntu 14.04.1 LTS, and

3.13.0-65-generic #105-Ubuntu SMP Mon Sep 21 18:50:58 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux for Ubuntu 14.04.3 LTS

I'm attaching also a couple of log files detailing the modules loaded in both cases.
Regards,

Hi,
Just a quick update/hint on this issue. We had tested that everything is fine until kernel 3.13.0-64-generic is installed (i.e. 3.13.0-63-generic is the last kernel where this problem does not show up).

We have tested this booting the system through the "Advanced options for Ubuntu" in the grub booting screen and selecting the adequate kernel image. This is also an EMERGENCY shortcut to deal with this problem.

This issue is clearly related to reading data from a USB device. While dealing with these tests, we found also an unexpected problem with a USB XBee adapter where outgoing messages were sent without problem but incoming messages were not received (in esence the same problem with bossac). This problem was solved also if a 3.13.0-63-generic (or previous) kernel was used.

Regards

What usb port are you using? The one connected to the DUE or the one connected to the 16u2.
If its the 2nd, then its probably a delay problem. the chip erase and reset timing might be wrong due to a lagg. USB2 or 3 used here? with USB HUB and which version (2.0 HUB or 3.0)?

[Atirma]

Hi,
This problem occurs independently of the port used. They were connected to a USB 2.0 port.
Regards

[NicoHood]

You mean on the DUE USB port and the 16u2 USB Port? (you know your arduino has 2 usb plugs).
Have you tested something like an uno or leonardo too?

[Atirma]

Yes, we found this problem with the two DUE's ports (the programming port and the native port). However, we haven't tested other boards yet.

[NicoHood]

Other boards would be nice to test. I only have AVR boards, but I programmed/modified a lot of the bootloaders. So I could play with this under my linux (where everything runs fine though).

The changelog between 3.13.0-63 and 3.13.0-64 (https://launchpad.net/ubuntu/+source/linux/3.13.0-64.104) shows that a bunch of modifications has been made for both the tty and the usb subsystems.
Particularly, I'm afraid that this two commits can be related with the problem:

  * xhci: Calculate old endpoints correctly on device reset
    - LP: #1493305
  * n_tty: Refactor input_available_p() by call site
    - LP: #1397976

However we can only report this issue to Ubuntu maintainers as a generic bug until we are able to bisect the offending commit

We are not alone 😄 https://bugreports.qt.io/browse/QTBUG-48499
