Hello,<br>

First, sorry, this mail is quite long, because of logs.<br>

The battery looks good and since you can charge with your external charger it must be something else.
Can you run the charger-script:
<a href="http://git.goldelico.com/?p=gta04-rootfs.git;a=blob;f=debian/config/root/charger;h=67f7355a237e69734e9a2c109c1511c7e8e1685f;hb=HEAD">http://git.goldelico.com/?p=gta04-rootfs.git;a=blob;f=debian/config/root/charger;h=67f7355a237e69734e9a2c109c1511c7e8e1685f;hb=HEAD</a>

Or even trace (may not run on 2.6.32 kernel)

run with ./batt 1 and watch how values change when plugging/unplugging the charger(s).

I've downloaded these two scripts and ran them on the GTA04 with these results :<br>

Next unplug/replug have same results than the last one (floating id). Is it an issue of not re-initialized value for id ?<br>
Do you need more trace ?<br>

Thanks,<br>
Adrien<br></div></blockquote></div><br></div><div>So in summary it appears that the Openmoko charger (any maybe your USB cable) is sometimes providing</div><div>less than 4.4V which makes the charging hardware stop automatically (and never restart).</div><div><br></div><div>You should also be able to test that by continuously running the ./batt.sh 1 script and then unplug/replug</div><div>the charger. This could show a pattern like the VBUS voltage is going to 4.8V and then fluctuating heavily</div><div>and suddenly it goes below 4.4V and the "temperature" goes from 26C to 56C. At that momen the charging</div><div>has stopped.</div><div><br></div><div>What could be the reasons? Most likely a mechanical issue with the USB connectors giving a weak contact.</div><div>Either the cables (dust?) od the USB socket on the GTA04. I.e. the plug on your external battery may be</div><div>newer and have stronger springs in the contacts or whatever.</div><div><br></div><div>So please try to find out if that could be the reason. If the OTG socket on the GTA04 is weak we may need</div><div>to find someone with soldering skills living near you.</div><div><br></div><div>BR,</div><div>Nikolaus</div><div><br></div></body></html>
