Ubuntu 9.10 x64 hanging (possible java issue ?)

[Quan-Time]

Read the other thread, to no avail, cant figure out whats going on.

Code: Select all

$ java -version
java version "1.6.0_15"
Java(TM) SE Runtime Environment (build 1.6.0_15-b03)
Java HotSpot(TM) 64-Bit Server VM (build 14.1-b02, mixed mode)

All the sun packages are installed and on, but i cant seem to make them the active ones.

Ideas ?

That looks like the right java.

What is it doing? Hanging on start up?

Check in the TunerStudioLogFile.txt What are the last lines before it hangs?

I can get it to load now, but when i try to detect ECU version, it dumps out.. I cant set anything via "communications" either. its all grey'd out. I CAN play with mini-terminal, but thats all.. Cant do anythnig in there either.

If i manually select ECU, it lets me choose some variables (degF or degC, etc..) and then it bombs out again with this at the end of the log file.

Not sure if this applies to Ubuntu, but on Fedora I had to add my userid to the "uucp" group:

/etc/groups
...
uucp14:uucp,jsm
...

Prior to that I had been struggling to get serial comms to function. They would work if I logged in as root, but not a normal user.

Normally i dont get anything, but cos i did sudo, i got that,, any clue ?

[LT401Vette]

Check the date on your computer, delete user.properties then try to start it.

[Quan-Time]

nope, same problem.

If i run it with sudo, i get to choosing firmware, without sudo, it just hangs at the splash. Anything else i can try ?

[LT401Vette]

Let me see a new log snippet. The one above showed you date at Aug 2010, so now we may be on to new problem.

One without sudo, one with..

As for the date.. I think you will find i follow the world standard of time and date formatting, as does most of the world.. dd/mm/yy , i guarantee you my date says saturday jan 9th.

Ah... My bad assumed in US format

I'm not quite understanding the why sudo is doing anything for you. Where is the app installed? Is it and your project in a place where you would have write permissions without sudo?

Permissions can come into place for using the serial port, but even without those rights the app should be coming up.

[Quan-Time]

its in my home directory, so it shouldnt have any problems. copied / pasted to a new dir.. Bingo it works..

BUT im getting

OK, back to the "splash screen, try to detect ECU it dumps out" routine.. BUT i got a new log file.. For some reason it wouldnt create a proper log file.. dunno why.. anyawy, ive attached it for you to look at.

Now that looks more like some type of RXTX error, so would either be the wrong driver, but the error doesn't seem that way, or permissions. Is your user in uucp?

Agreed, and it sniffs a bit like my OSX 10.6 errors. Have you, Quan-Time, looked at SunSpot stuff on Linux and other serial driver stuff for 64bit?

There might be something here?

I looked at his machine, megatunix runs fine there and can talk to the ECU, so it's not a permissions issue. perhaps RXTX isn't 64 bit safe?

[Quan-Time]

as dj said, i can run megatunix without issue. It would point to some sort of other issue ? whats this about rxtx.. maybe that could be a clue ?

Just realised i DONT have uucp installed in my synaptic package manager.. relevant ?

NO re: uucp. He's talking about a permissions thing. Typicaly serial ports are owned by either:
root:dialout or root:uucp. (that's "user:group"),

On my machine I get this by default for my PL2303 adapter:

Code: Select all

dave@shrapnel:~/cvs/MegaTunix/src$ ls -l /dev/ttyUSB0 
crw-rw---- 1 root dialout 188, 0 2010-01-09 21:08 /dev/ttyUSB0

This means only the "root" user and other users in the "dialout" group can use this port with Read/write access. those threee dashes at the end of hte permissions block crw-rw---- are for "world", which means "everyone else". hence no one else is allowed. If you weren't in the dialout group (or whatever group owns your serial port/adapter), you wouldn't be able to use the serial port, and thus megatunix, megatune or tunerstudio would NOT work, since megatunix works, we know it is not permissions but a Tunerstudio/Java issue.

[Quan-Time]

Code: Select all

quantime@allenkey:~$ megatunix
quantime@allenkey:~$ ls -l /dev/ttyUSB0 
crw-rw---- 1 root dialout 188, 0 2010-01-10 12:24 /dev/ttyUSB0

hmm.. well, id still like this resolved.. If only for the sake of learning whats going on... cheers for the help thus far everyone.

[LT401Vette]

Does MegaTunix use lock files?
I believe that is where the problem starts. I have seen other apps able to use the port, but RXTX couldn't with the lock files until it had the right permissions.
From what I understand the RXTX 2.2 that is coming is supposed to be a bit less PITA about this, we'll see.

You should be ok with the 64 bit kernal, RXTX has a 64 bit linux driver. That is actually the only difference in the 64 bit version I have for download, the 64 bit driver is in place.

Dave, thanks for helping out. I'm pretty sure you know linux better than me!

[Quan-Time]

we all chat on IRC a fair bit. I helped him with the windows ports of the program (i dual boot) and often he helps me with linux Im sure we can figure something out. Im not sure about lock files either, im fairly sure he doesnt.. But ill let him answer it.

MegaTunix DOES use lock files, but not the semi-std one that some other comms programs use. (It probably should use the std one, but,at the time i didn't know the right info about it when i coded that feature. current MegaTunix creates its lock files in /tmp.)
