Booting GTA02v6 without battery (was: Re: Need battery help in DC area)
The Digital Pioneer digitalpion...@gmail.com writes: Uhhh, since when? The FR can't even run off of pure USB power for more than a few seconds. I can assure you i tried it myself on GTA02v6 many times and on most tries i could boot to NOR without battery. Probably it depends on how fast host can enumerate the device but for me it was enough to hold AUX, then plug USB, in case it didn't work hold AUX again, press POWER... Something like that in most cases lead me to NOR boot menu and there the battery can be charged.

Re: Need battery help in DC area
I'm guessing it will run for a while, but after 20 seconds or so it will die. That's what mine does. the few times i got a dead battery it was enough to plug in the fr to the wall charger and leave it alone for a few hours. then it was able to boot and thus to charge. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

This is an issue because the internal charging circuitry can not be turned on until the FreeRunner has booted, and booting through USB power alone does not work on early A5/6 devices.

From http://wiki.openmoko.org/wiki/Neo_FreeRunner_Battery#know_issues FWIW, I have an early GTA02v6 (date code: 20080722) and it does usually boot from USB power and always boots from the charger. -- Rask Ingemann Lambertsen Danish law requires addresses in e-mail to be logged and stored for a year ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Hardware mod for starting GTA02v5 without battery? (Was: Need battery help in DC area)

Is it a hardware mod or firmwae upgrade or something? It's a hardware mod. It's capacitor C1767, page four of the schematics[1] at the bottom. There's a (rather poor) picture of a reworked A5 here: http://lists.openmoko.org/pipermail/openmoko-kernel/2008-July/003963.html Better picture (of the whole A5 PCB without the rework): http://wiki.openmoko.org/wiki/Image:Gta02a5_pcba_cs.JPG Electrically, the rework is simple enough: Just connect a larger capacitor in parallel to the existing one. But it sits under the main can, so making it fit isn't easy. The picture of the reworked device isn't very good, but it looks like a capacitor has been connected to the VB_SYS side of R1768 and to the GND side of C1722. See URL:http://people.openmoko.org/werner/gta02-chg/ for an explanation of the problems GTA02v5 has starting without battery power. Btw, where is C1767 itself? I can't find it on either the assembly silkscreen[2] or the component placement drawing[3]. At 47 uF on the A6, it ought to be easy to spot.

Need battery help in DC area
My Freerunner battery is dead and I cannot boot it. Have tried the suggestions on the wiki, none of which work for me. So I need to find someone who can charge my battery, or someone whose battery I can borrow, or someone with a battery charger I can borrow or some such idea. Any help is greatly appreciated... Also, does anyone have instruction on how to fix my Freerunner so it can boot off USB or wall charger? Is it a hardware mod or firmwae upgrade or something? ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Re: Need battery help in DC area
Same with mine, but it can't actually run on USB power. Too bad. Heheh ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I can run with out battery (with usb cable connected :) ) only if it has booted. If just connect usb and try to boot FR. No it can't.
