Arduino googlecode checkout woes

[hummingbird]

I'm trying to dabble in MPGuino/OBDGuino code development.

Wanted to build my own Arduino environment, as a pre-built package is not available for my flavor of OS - Kubuntu/Jaunty 64-bit Linux.

I am following the instruction on the googlecode page for checking out the code properly (there is hardly any procedure before the code is checked out anyways). I still get stuck at precisely one point during checkout process, as indicated below -

$ svn checkout http://arduino.googlecode.com/svn/trunk/ arduino-read-only
...
A    arduino-read-only/build/shared/sketchbook/default
A    arduino-read-only/build/shared/sketchbook/examples
A    arduino-read-only/build/macosx
A    arduino-read-only/build/macosx/dist
A    arduino-read-only/build/macosx/dist/librxtxSerial.jnilib
svn: REPORT of '/svn/!svn/vcc/default': Could not read response body:
 connection was closed by server (http://arduino.googlecode.com)

Before giving out the svn error, the terminal was stuck for a loooong time at the librxtxSerial.jnilib line.

Please let me know where I am getting wrong. Thanks!

To be honest, I've only ever checked in. If I want to start over from the last release I just go to http://opengauge.googlecode.com/svn/...no/mpguino.pde and cut and paste the program back onto my pc.

Also worth noting that the version there is the last arduino compatible version, as mentioned with the last update notes: http://ecomodder.com/forum/showthrea...html#post93357

Then maybe I have little hope of finding help...?

[dcb]

I don't understand. You can get the code now right? That wasn't helpful?

Edit: reread, ok you were looking for arduino help too it seems. Yah I have to get away from arduino. It is completely awesome for getting started, but I was fighting with it very soon after getting started.

BTW is there going to be a move away from the arduino to have a standalone implementation? I feel quite hampered, as I have an avr compiler, avrdude, and I'm still wrestling with the arduino environment...

[dcb]

For the googlecode version yes, it is standalone CPP. I just haven't gotten around to checking in the 0.80 CPP file yet. Had to be that way for a more reliable pre-built product that didn't have me chasing my tail for every cpu or OS imaginable, or when the next version of arduino breaks the program (like what happened 6 hours after I announced it's release ), or when someone has a problem with 64 bit linux or mac OS that I shouldn't have to care about

If there's any doubt left though, I'm done dealing with the arduino framework. Arduino.cc, and probably a few people here, have plenty of good tips though.

Edit: avrfreaks.net is an awesome non-arduino specific avr resource as well.

[hummingbird]

Sorry for sounding like an oaf, but the above discussion means it is not necessary to have anything arduino specific in the code for the MPGuino - everything is standalone, and there are no dependencies outside the MPGuino source code itself.

This would mean I can compile it using a plain AVR cross-compiler, burn it in the uC and expect it to run.

Right?

[dcb]

Correct. I burn it with a usbtinyisp and a press-on adapter (made out of a spare bbb board that paulb sent me), but the parallel ISP programmer works well under linux too (and is dirt cheap). You are on your own with the 64 bit stuff, and different OS's create different sized hex files with avr_gcc, go figure. I currently get the smallest hex files with whatever gcc came with arduino-0011 under windows XP.
