[08:07:10] *** GPSFan has joined #zipit
[08:27:43] <T0mW> GPSFan: did you ever get OE running on the Zipit?
[08:28:20] <GPSFan> T0mW: no, I gave up again after the build broke yet again.
[08:28:44] <GPSFan> I've been working on blob and some other low level stuff.
[08:28:49] <T0mW> you used the directions on the zipit website, correct?
[08:29:35] <GPSFan> this was after you helmed me to get it building that once. I tried to change something (it's been a while) and the build just broke.
[08:29:40] <T0mW> I've found that if you use the 'stable' branch of OE instead of 'dev', then use angstrom-2007 as the distro, things will build ok.
[08:30:02] <T0mW> the dev branch is usually broken
[08:30:34] <GPSFan> I'm also put off by the 6+ hour build time.
[08:30:48] *** asantoni has joined #zipit
[08:30:55] <T0mW> and, angstrom-2008 is bleeding edge
[08:31:04] <T0mW> GPSFan: oh? It only takes me an hour or less
[08:31:16] <T0mW> Q6600 + 8Gig of RAM
[08:31:18] <T0mW> ;)
[08:31:22] <GPSFan> yeah, on your spiffy new 8 core box.
[08:32:21] <T0mW> I wish I had 8 cores, the intel cpu blasts through the code. The AMD X2 6400 I purchased was such a dog that I pulled the board and replaced it with the intel quad
[08:32:45] <GPSFan> 'scuse me... 4 cores...
[08:32:49] <T0mW> I got gpe running. I just cannot get past the gui login screen.
[08:33:08] <T0mW> I was thinking of giving opie a try
[08:33:16] <GPSFan> does the keyboard work, what did you use for a mouse?
[08:33:26] <T0mW> no mouse, just the tab key
[08:33:40] <T0mW> the zipit keyboard works in X
[08:33:43] <GPSFan> can you type int the login box?
[08:33:45] <T0mW> yes
[08:33:50] <GPSFan> k
[08:34:06] <GPSFan> and you can't login
[08:34:16] <T0mW> I was thinking of putting the howto up on openzipit.org
[08:34:26] <GPSFan> good thinking
[08:34:28] <T0mW> just so others can get to the point where I am
[08:34:44] <T0mW> I have another makefile and stole a few ideas from poky as to how to setup the build environment.
[08:34:54] <T0mW> less hassle
[08:36:18] <T0mW> right now I'm doing some kernel work, chasing down a potential problem with the enc28j60 driver. I used that chip on two s3c2410 designs.
[08:36:51] <GPSFan> using the spi framework?
[08:37:39] <T0mW> yes, the one board currently only has one spi device. the other (HammerLCD) uses both spi controllers: enc28j60 and MMC
[08:38:07] <GPSFan> how is performance? It sucked on the hammer using bit-banged i/o
[08:38:11] <T0mW> I've got a MAC error from the enc28j60 that might be the fault of the new spi framework.
[08:38:22] <T0mW> GPSFan: 300kB/s
[08:38:36] <T0mW> that is from hdparm
[08:38:40] <T0mW> doh
[08:38:47] <GPSFan> wow, that's much better than the 200kbits/sec that I got.
[08:38:53] *** FireEgl has quit IRC
[08:38:54] <T0mW> no, that was it, hdparm.
[08:39:00] <T0mW> faster CPU
[08:39:07] <GPSFan> heh
[08:39:23] <T0mW> IIRC, the Z1 was 90MHz?
[08:39:46] <GPSFan> after the kernel tweaks, it started out at 75
[08:39:51] <T0mW> yeah
[08:40:48] <T0mW> I think that the Hammer board would be much better off if they had only brought out one SPI and replaced the other with the SDI
[08:41:02] <T0mW> oh well
[08:42:36] <T0mW> it is fun working inside the kernel again. It has been a while since I've done that.
[08:42:51] <T0mW> frustrating too
[08:46:47] <GPSFan> yeah, many changes between 2.6.21 and 2.6.26.rcx
[08:46:58] <T0mW> a lot
[08:47:42] <T0mW> the SDI is not in the release candidates (linux-2.6.26-rc6), you still have to patch it in.
[08:48:01] <T0mW> at least for the samsung cpus
[08:53:02] <T0mW> GPSFan: there is a way in OE to use an external toolchain. By doing that, you can cut down on the time it takes to do a build as you don't have to waste it on the dev tools.
[08:53:13] <T0mW> GPSFan: I just haven't figured out how to do that
[08:53:45] <GPSFan> that would be a useful feature. also to be able to use uclibc
[08:54:32] <T0mW> Dave was looking to do that. I don't think he got good results
