gpsd on a zaurus 6000L


I have a fortuna U2 gps puck that I am trying to get working with gpsd on a Zaurus 6000L.
I have cross compiled a pl2303 driver so the gps shows up on /dev/ttyUSB0
I can minicom on to /dev/ttyUSB0 and watch the NMEA stream scroll down the screen.

but what ever i do I can't get gpsd to see it.

I ran gpsd -p /dev/ttyUSB0 -s 4800 (the same port and speed I used in minicom)

when I telnet onto 127.0.0.1 2947 I get nothing (except 'GPSD' if I hit return)

Can anyone help?

Would you believe it! I've been playing with this for weeks now (literally) and got absolutely nothing.
Within 20 mins of posting this and after stabbing a few random keys the little bugger starts working.

it seems that hitting 'r' and pressing return magically gets the nmea stream showing through telnet.

gpsd on a zaurus 6000L

Hello skunkburner

I have the Zaurus-similar unit 'Archos PMA430' (running on ARM / Linux 2.4.19-rmk7-omap1) and the same 'Fortuna U2 USB GPS' receiver as you. I have downloaded the linux driver (pl2303_v0213) but it's not compiled and have no idea how to. Could you post a copy of your compiled driver or maybe give short instructions on how to compile it? - (I'm using FC3)

I'm using 'qpeGPS 0.9.2.3 pre' on the PMA430 with the following arguments -p /dev/ttyS0 -s 4800 and host as 127.0.0.1:2947

Hi forestmountain

I'm afraid your out of luck for my pre-compiled version. My kernel is 2.4.18-rmk7-pxa-embedix so the kernel module I have compiled won't work with your kernel : (

I think I ended up cross-compiling the driver (tho' I might have compiled the driver on my Zaurus I can't remember - It was a long time ago)!

Either way I needed (apart from gcc) the kernel source for my Zaurus (the pl2303 driver has been included in the Linux kernel for a while).
*Note* I couldn't get the driver from Prolifics site to compile. I had to use the one that came with the kernel.

There are plenty of tutorials on the net about cross compiling (remember google is your friend) so I won't tell you how to do that!

I found this one very helpful - but it is specifically for the Zaurus.

http://linuxdevices.com/articles/AT6830035793.html

If you manage to get gcc for your Archos

From your kernel source find the '/linux/drivers/usb/serial/' dir.
within that will be pl2303.c & pl2303.h

to compile them type (as root) 'gcc pl2303.c'


Hope this helps

Hi Skunkburner.

Thanks! You have been much helpful.

Archos has just released the SDK for the PMA (including gcc) so I think there's a chance of getting it to work.

Nice link!
