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

Also, what do you get for

Code:

ls -l /lib/modules/*/kernel/drivers/usb/serial/ftdi_sio.ko

Okay, "No such file or directory." Looks like ftdi is not installed. I'll see what I can do about getting that.

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?

Ack! I can't get it out to the car right now. If I apply 12 volts to the proper OBDII pins on the plug, will that at least wake it up?

Yes it should. This is something I am considering doing due to the PITA it is to test this obd stuff. I have not tried it, but according to

http://en.wikipedia.org/wiki/On-Boar...nostics#OBD-II

You need 12v on pin 16 and ground pin 4 and it should be live

I just tested this and it works fine (in so far as at least registering as a USB device and loading the driver).

Sorry for being a noob, but I found an ftdi package and am trying to build it. What is the variable issue?

Beautiful! Thanks. It made just fine.

I now have obdiigpslogger compiled on the ARM and also FTDI installed.

I'll test it tomorrow.

Woo!
