Hostmode while charging


Plugged in memstick, by using http://talk.maemo.org/showthread.php...080#post907080 cable.
Started high speed hostmode, VBUS boost, and mounted.
THEN I plugged in the charger of cable nest linked above (it is very important to plug in the external charger after correct establishing of hostmode, particularly not before you've hit "VBUS boost on", in h-e-n GUI. Also do NOT connect the unpowered charger to cable after you started VBUS boost - either keep it plugged to cable from beginning and just plug into mains later, or first plug into mains and then to Y-cable)


t900:~# logger stopping vboost && boostoff
t900:~# ls /media/sda1/

[edit: that's probably cruft, not needed when using the normal booston/off scripts]

I have an improved booston and boostoff script here, but it will work with the original one as well.
charger script is the one of ShadowJK: http://enivax.net/jk/n900/charge.sh.txt, only slightly renamed and some added debug prints.


To stop the whole thing, you first kill charger, then stop h-e-n

cheers
