Thread: How to get this to work on an ARM processor?

Or, rather than cross-compiling, I read your thread Make fun of the noob; if you have a real flavor of ubuntu 9.04 on there, you might find you just need to do "sudo apt-get install cmake" on the device, and everything will magically turn up. Then you can follow my usual build instructions, but actually run it on the device...

I tried to make and install and I think it worked. Does this mean it compiled for the Sheeva?

Code:

That's actually on the sheeva? Awesome stuff, looks exactly right.

You even have fltk installed, which means that you can run the gui version on a remote system.

Okay, indeed it appears as if I've got obdgpslogger compiled and installed on the Sheeva.

Code:

bugbyte@iPlug:/dev$ obdgpslogger -h
Usage: obdgpslogger [params]
   [-s|--serial[=/dev/cu.OBDKeyPro-DevB-1]]
   [-c|--count[=infinite]]
   [-n|--no-autotrip]
   [-t|--spam-stdout]
   [-p|--capabilities]
   [-o|--enable-optimisations]
   [-l|--serial-log=<filename>]
   [-a|--samplerate[=1]]
   [-d|--db[=./obdlogger.db]]
   [-v|--version] [-h|--help]

Now, I need to find FTDI for the Sheeva so I can plug in my OBD cable?

BTW, I plugged in my OBDPRO Scantool and it did NOT show up in /dev. Will it show up without being plugged into the car?

On a Mac, the simplest is to fire up the X11 server (may need to install it from CD first) and ssh to the sheeva with X11 forwarding enabled. It should "just work" (tm).

If you're using leopard, you already have it. You don't need to "fire it up", it will magically do the right thing when you ssh with X forwarding enabled. I cannot strongly enough urge you to update X11 on leopard if you're using it, though. Apple aren't pushing out updates through software update, but you can download an official[ish] update package from here: http://xquartz.macosforge.org/trac/wiki

Really, the best thing to do is have a real linux install. I'm using VirtualBox with great success; if you don't have a PC with linux installed on it already, I strongly recommend installing Ubuntu 9.04 in a virtualbox. Life just gets easier, the same way that it does if you want to talk to a Windows box; the simplest way to do it is with another Windows box.

Have fun,

It should be identified (and the ftdi module should be on the sheeva) and most likely will say it is assigned /dev/ttyUSB0.

Report back and we should be able to help from there.

Here's what I got. Curious. I had to hit Ctrl-C to break out of it.

Code:

bugbyte@iPlug:/dev$ lsmod | grep ftdi
bugbyte@iPlug:/dev$

See what lsmod shows on its own, without piping it into grep.

When running tail -f /var/log/messages, did you not get anything when you plugged and unplugged the device? What about if you run "dmesg" after?
