Design your next openmoko/qi/openwhatever linux pda and leave in a usb port and a cavity for the smallest 3G usb stick. Maybe place it on the end of the phone and reduce the case size later. It's not perfect, but it allows replacement of the cell module which gives you lots of flexibility. Similar things already happen -- QI's Ben gets wifi for free with an SD card slot. It just became much more useful. This is just an example that you don't need a pot of gold for everything. These solutions aren't for everyone, and neither is GNU/Linux on the desktop, but for some it will be the preferred choice. Open hardware is still fairly new -- and you _can_ make progress without pots of gold. You won't be able to get everything, but you might get more (look at GNU/Linux's progress, although I know big companies support some of its development now).

I'm sure everybody who has any professional connections with Freerunner+Glamo development already took all possible measures to solve this problem. But what concrete steps were taken to ease Glamo bottleneck? If its throughput is so narrow, can we lower amount of none. it's a hardware issue. you simply cant read or write to video ram faster than that. andy tried timing stuff all that happened was instability from memory. glamo is most likely also the cause for the cpu runnig at 400 not 500mhz. the extra load on the memory bus (because glamo is hooked there externally providing another addressable chip) probably caused the instability. remove it and there is a big change the cpu could run at 500mhz instead of 400. it's rated to do 500. (yes power consumption would go up - but it'd only be up while its on. when suspended it wont matter). data flowing through it? There's one neighbor unanswered thread with a render on the device - and this will then limit what you can render. evas can't be fully accelerated by the glamo. it has too many opretations. a bit like asking why quake4 is slow on a a voodoo2. it does much mroe than the old gfx chip ever was designed to do and you will hit software fallbacks. evas has multiple engnines. software (which is what is used - the 16bit renderer as opposed to the full 32bit one). it has xrender - if xrender were fully accelerated this should be better, but glamo cannot fully accelerate all the ops evas uses, so... it will rely on software fallbacks. thus slow down. my bet is you'll end up same speed as the pure software engine, or worse. aftera bunch of hard work you'll have gone nowhere. evas also has a gl and gles2 engine - but thats no use on glamo. it's gles1.1 and very limited (from memory texture size is 256x256 which is pretty useless for 2d as most data you deal with breaks these bounds). question on how to start the kernel with qvga resolution. Aside of no need to do that - just configure x for qgva. :) this, what can be reduced, for example amount of available colours (256 or even 16)? And if this [too] low throughput only of video memory channel? 256 won't help. it increases complexity and really reduces display quality through the floor. the best best is qvga 16bpp. its simple. it doesn't require any hard work. it is actually the most common resolution for most phones and devices out there so the software is more portable if you work on that (and then higher). but... in the past everyone has moaned and complained and refused to use it, and insisted on their vga resolution... and then complained about speed. if people don't believe me that the gta02 is just plain a bad bit of hardware and you have few choices here's some examples. here'es an ooold efl demo app i did: http://www.rasterman.com/files/eem.avi and here it is on a 206mhz ipaq 3660 with 64m ram and 16m flash, qvga(240x320). it's from like 2001/2002 (from memory). its ancient. and watch it run evas: http://www.rasterman.com/files/eem-live.avi here is something i videoed today. it's an samsung s3c6410 at 667 mhz, 128m ram, and 800x480 (higher res than gta02): http://www.rasterman.com/files/ello-elementary-smartq5.mp4 everywhere i look... theres much better hardware. if you look at performance vs age of hardware (when it was released) gta02 is almost at the bottom of the pile. :( you simply have a bad piece of hardware if you want graphics performance. as soon as you acknowledge that and either downgrade the device resolution for example to bring it in line with its performance, or just use different hardware, the better life will be :) I agree with you Vasco, (about switching to QVGA) for the most part, but a long time ago when Carsten asked this question, much of the community responded that they wanted to keep the high res screen. Things like viewing webpages at 640x480 instead of qvga, viewing maps, etc. were cited as useful and important. Anyway, I agree we should make QVGA work well, and I would use it for most apps. We should also keep in mind ways to allow use of the high res screen -- maybe picking certain apps (like browsers) that could switch to VGA automatically, and making sure the transition between resolutions is a smooth, fast, and automatic

Re: USB networking with Ubuntu 9.04
I copied Sander's exact lines into /etc/network/interfaces (I changed
eth2 to usb0 -- I don't know if that matters) on my ubuntu 9.04 laptop
and it's working for me. I have plugged and unplugged the cable a
couple times and no longer have to run my manual script each time.
Thanks!

It can be done automatically just by putting the right stuff in

auto eth2

if you would tell me wich of / or both tricks did it on your system ?
but i had to add this two lines to my /etc/ufw/ufw.conf
ufw allow from 192.168.0.202
ufw allow to 192.168.0.202
another trial with iptables needs to load some modules too:
#!/bin/sh
MOKO=192.168.0.202
echo 1 /proc/sys/net/ipv4/ip_forward
modprobe ipt_MASQUERADE
iptables -I FORWARD -j ACCEPT -d ${MOKO}/32
iptables -I FORWARD -j ACCEPT -s ${MOKO}/32
iptables -I POSTROUTING -t nat -j MASQUERADE -s ${MOKO}/32
what works was the script Cristian Gomez included in his reply!
Just for the records, the first time I run that script it does assign
the
192.168.0.200 IP to eth1 but can't ping/access 192.168.0.202! Then:
- I disconnect Openmoko
- connect it again
- re-run the script and voila the connection is there!

No, not all FR are affected, AFAIK I've been wondering the same thing... It would seem that the extra current draw in suspend would affect all FRs, so having a #1024 fix-party would be a good idea in any case (?). #1024 is not causing extra current drain, but the software solution to this bug: Not allowing Calypso entering deep sleep mode. You can check if your FR is suffering from #1024 editting /etc/frameworkd.conf and changing ti_calypso_deep_sleep = never to ti_calypso_deep_sleep = always then restarting framework: /etc/init.d/frameworkd restart After doing so, if your FR suffers from this bug, your modem will continuously register/unregister from GSM network when suspended, and you will lose calls On my case, it was nearly impossible to call FR when suspended + calypso deep sleep. But not all FR suffer from this bug. You should try it after fixing it. Most of GTA02-A5/A6 have this bug. Once TI_CALYPSO_DEEP_SLEEP set to always, you can check with a little script done by KaZEr (see bleow) Launch it on screen, and redirect output to a file.

Re: [FSO][M4] Missing Components?
I believe it depends on which image you install. zhone came installed on the openmoko-fso-image-glibc-ipk... image I installed. fso-illume-image and fso-console-image probably come without zhone pre-installed, I'm using a neo1973, so there's a slight chance the behavior on the freerunner images is slightly different.

Re: Freerunner and external Display
Ah darn, but at least it should work for presentations or slideshows...and maybe pong :) if drivers support partial updates. Here are some framerate estimates -- feel free to correct me if anything looks off: (most devices mention USB 2.0, hopefully they also work with USB 1.1) QVGA: max: 13 FPS. Assuming QVGA is supported in hardware/driver. one of rasterman's earlier mails mentioned QVGA is about 320*240*1.5bytes per frame 640x480x8bit, max: 5 FPS Some devices mention this mode (640x480x8bits) Note: USB 1.1: max: 12 Mbit/sec or 1.5 MBytes per sec Here are some resources I found quickly while looking around.
