I’m trying to upload a program to my Arduino Uno that is connected to my Chromebook. I’m using the online editor http://editor.makeblock.com/ide.html. The Chromebook connects over USB just fine to the Arduino, but when I click to upload, I get an error:
Exception in thread “main” java.awt.AWTError : can’t connect to X11 window server…
followed by a bunch more line (that it doesn’t let me copy-paste).
Any ideas?
Thanks for the feedback. We checked the server, should be fine now, please have a try.
Thanks for the quick response! The java error is gone and it seems to compile fine. However, it says it cannot communicate with the board when it tries to upload to Arduino. It says that I’m connected to the board on the upper right of the screen. I tried the “update firmware (USB)” from the connection menu, but it gives the same error.
On a PC, the online editor doesn’t even finish to compile. After the "Verifying… step, it says:
ax1838hs.cpp:2:22: fatal error: IRremote.h: No such file or directory
Don’t know if the two errors are related…
Thanks!
Windows and Mac work fine since last Friday. ChromeOS uses same code server, it should be working too.
For your issue, please make sure the correct main board was selected, no other program like arduino has taken up the serial, and give me the screen shot of whole error, as well as your code.
Please see below for pictures at each step. It’s exactly the same steps on a PC or a Chromebook and the same error. I no longer see the “fatal error” I mentionned before, but now it says it can’t communicate with the board.
Thanks for your help!
same issue occurring here with Arduino Uno using mblock on chromeOS (extension installed).
The chromebooks are bound to an edu domain, so there may be restrictions that need relaxing? We can add exceptions to popup/redirects without getting ICT techs involved. Would love to know exactly what the background process is.
Same code that is failing installs from OSX platform no issues.
I am also in an education environment, so firewall restrictions may indeed be an issue. Any way to check this?
How’s that checking going on.
We are near ready to abandon the whole project for lack of ability for the students to program their arduinos from chromebooks
After the discussion, there is no update for mBlock 3 series. So I am afraid this issue won’t be fixed.
But we are going to release mBlock 5 ChromeOS version recently, then we can use mBlock 5.
from where I am sitting, the issue is probably with the cross domain compilation that i’ve heard about - if you guys could just let us know what is going on, technically, in the background, then I’m sure the security dudes at the school could add the required exceptions to their firewalls / security.
i’m sure you understand that for kids, a week is a long time. a month is a significant portion of their lives. There’s no eta even posted on mblock 5 for chromebooks…
