OpenZaurus/Opie/Qtopia / Making It Simpler
« on: July 12, 2005, 06:36:44 pm »
I have my Zaurus 5500 running Opie, and I've been trying to get a working cross compiler for it.  OE is far to complicated for me to set up because I keep getting into that... this software requires this software which requires this software which requires a software whose build script is broken.    

All I need is GCC and/or G++.  Having a GUI would be nice, but at this point, having Hello World is a miracle.

In any case, I'm also developing for another embedded system.  I don't think the processors are the same.  The other system has a PXA255 in it, and the cross compiler that I have working seems to make Hello World just fine for the Zaurus.  So, if I built another compiler for the Zaurus (I'm doing a client-server app) what would be the differences?  Is there a real need to build a second compiler when I already have one ARM cross-compiler working (albiet for a slightly different processor?)

Angstrom & OpenZaurus / Setting Up Wifi Problem/questions
« on: July 08, 2005, 02:55:06 pm »
Okay.  I flashed this SL5500 with the 3.5.3 and Hentages.  It's all hunky-dory, but I can't figure out how to get the WiFi card to connect.

I have a WEP encrypted adhoc network, and I just can't seem to get the network settings happy. First off, it's confusing to me that there's both a wifi0 and a wlan0 device that are up and happy (my Zaurus is only connected to power at the moment.)

Okay, so I try to set wifi0.  I set the mode, the ESSID, the channel, use encrypition with this key, and then set my static TCP/IP stuff.  I try to ping another device on my network.  It doesn't work, and I discover that the wifi0 device is getting no signal.  I cannot stop it, because I get an error message saying it cannot be stopped.  I try to configure the wlan0 device the same way as the wifi0 device.  It does get a signal.  (But it still cannot be stopped or restarted.)

What confuses me is that the signal is 64%, noise is 64%, quality is 0%, and the ESSID in the interface info window (under 802.11b) keeps refreshing every second with some weird set of characters appended onto the ESSID.  For example, my ESSID is MYADHOC (very creative, I know.)  the ESSID listed in this screen keeps showing the three ESSIDs:

What the heck?

Anyhow, the ping reports no packets are received.  The device I'm pinging is three feet away, and they're both away from any big EM producers.  Something's up (because I could connect before I flashed) and I'm not entirely sure what's being unfriendly.
