OLS was working but now gives me a java error

What values are you entering in the client regarding the analyzer port and speed?

Hi, that

Code: Select all

java.lang.UnsupportedOperationException: Desktop API is not supported on the current platform
   at java.awt.Desktop.getDesktop(Desktop.java:144)

was also new to me.

But I never used the java.awt.Destktop.class anyway.

I tried changing it to different ports and got the a URI error. Then I changed it back to /dev/ttyACM0 and it works just fine now. Thanks for the help!

Hi;
I am having the same/similar problem.
This is on a Linux Mint 13 X64 box.

0.9.4 works fine.
I tried 0.9.6 and this is the result:

So it is Kernel 3.2.0-23-generic

$ pwd
/home/mick/Downloads/OLS/ols-0.9.6.1

./run.sh
GUI starts fine.

Show Device Metadata - does nothing. (it does blink)

Changing the port speed does not help

[jawi]

Hi, that

Code: Select all

java.lang.UnsupportedOperationException: Desktop API is not supported on the current platform

But I never used the java.awt.Destktop.class anyway.

Hmm, overlooked that issue. After some quick tests, it appears that the mail support on various Linux distributions does not work reliably (maybe due to the lack of a configured mail client?).

I've created another issue for this, so it can be solved...

[jawi]

I tried changing it to different ports and got the a URI error. Then I changed it back to /dev/ttyACM0 and it works just fine now. Thanks for the help!

Ok, good to hear. In summary: the issue was that the analyzer port was incorrect, and that after resetting it to the expected value, it worked?

It looks that way. I'm not sure how the port got changed though.

[Fettlaus]

I have exactly the same error. I tried deleting the settings, changing rights of /dev/ttyACM0 to 777, using ttyACM0 as well as OpenLogicSniffer as "Analyzer port" (speed always at 115200).

I even tried using different, totally unrelated, ports. (As a previous poster jdd suggested)

[jawi]

You're probably suffering from issue #133. You can try whether the latest snapshot of the 0.9.7 works for you...

[Fettlaus]

I'm sorry, but that didn't help. I still get the same error. (showing different line numbers though)
I also deleted the old settings file.

I have to add, that I just received my Logic Sniffer. So I can't say that it was working at some point in time.

But I was able to do an update of the FPGA and PIC so it should theoratically be working.

[Fettlaus]

Seems to be my fault. Running as root works.
Not the best possible solution but a solution nonetheless.

[mwilson]

I wonder if this isn't a more pervasive problem. I have similar issues trying to run the `screen` program to communicate with the Bus Pirate under Ubuntu 10.04. It seems as though comm. software wants to create pseudo-TTYs in a directory called /dev/pts , and permissions there are set to rwxr-xr-x i.e. writable only by root. It sometimes seems as though setting group permissions to rwx, and putting my user in the appropriate group, makes things go smoothly.

If that truly is the case then it's not Jawi's problem at all, but I haven't been able to chase down the software that sets the default permissions on /dev/pts .
