Hi,
when my gta02v5 battery is completely empty I have two problems booting again
at all:
1) NAND u-boot does not work:
after connecting AC charger I can start only NOR boot (aux button first),
but the NAND boot (no aux button, only pwr button for 10+ seconds just
does nothing, the aux button doesn't blink then either).
removing power and battery for some 10 seconds doesn't help.
just charging 10 minutes (using AC charger) before trying [nand] boot doesn't
help right now either.
update (I write this email because right now I'm that "out of power mode
again":-(
after 10+ minutes connection to AC charger (still powered off) I can't even
get into the NOR boot anymore.
I removed the battery and AC, reconnected both and NOR boot came up.
here I selected "power off" and tried to do a regular NAND boot (no aux) --
doesn't react.
now NOR boot doesn't work either.
after some waiting (1 min?) NOR boot comes up again, now I selected "reboot"
(is this supposed to re-boot the nand uboot?). the screen got white for ~2
seconds,
than black again and that's it:-(
what's going wrong here ??
2) boot process crashes (switches off) with usb power from notebook
if I connect the FR to my notebook (Lenovo T61p) for power and once I manage to
boot,
the boot just crashes after a while (1-2+ minutes), I only have a black screen
then
and all I can do to boot again (long pwr on). usually in this situation all
futher
tries to boot won't come up either.
I'm not sure if these crashes might be triggered by the notebook having some
USB problems
("device not accepting address ...") and thus disabling usb power for that port
("port 2 disabled by hub (EMI?), re-enabling...") or if that hub-disabling is
only
a result of the FR already being crashed or switched off during boot.
solution in this case: I removed the empty battery, replaced it with the
battery
of my "real" (nokia) phone (nokia). then boot works, and while FR is running and
connected to the notebook I swap batteries again and charge the empty FR
battery.
I had this situation(2) at least 3-4 times before using various
uboot/kernel/distro versions,
I only started using the AC charger yesterday and realized, that it supplies
much higher current and charging goes much faster (almost a fator 3 in charging
rate!)
are these known problems ?
how can I get the FR up with empty batteries, how to charge an empty battery ?
thanks for any hint or comment,
Harald
