In the list archives, I see there has been much discussion | about WiFi power management. It appears that you can't really turn off WiFi | power. It's a bit of a saga, but the end result seems unbinding the driver from the device or now they are modular in packaging config, rmmod-ing the modules should do well for power on andy-tracking HEAD. Previously there was a pin on the module that looked like an on-off control, but it turned out it was nothing of the sort. | Playing with the openmoko-panel-plugin gives: | | BT on increases current draw by 7,5 mA @ 3,79 V. | GPS on increases current draw by 47 mA @ 3,79 V. | | For both BT and GPS, current draw reduces to the previous level by | turning off the device through openmoko-panel-plugin. On to GSM: Sounds good, although the GPS side may change its consumption radically depending on whether it has acquired the satellites or not. | GSM off further increases current draw by 17 mA @ 3,80 V. :-( | GSM on now _decreases_ current draw by 17 mA @ 3,80 V. Lol. | I reboot with 'shutdown -r now', hold AUX to get into NOR u-boot and boot | from SD-card. That also recovers the 2,2 mA initially drawn by GSM. All these things with closed firmware and private state are full of surprises. Do we know what the panel-plugin sources are doing to turn it off? Sending AT commands, or using the /sys, or both? - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkl1r0MACgkQOjLpvpq7dMppAQCghfMmZT1CpxWIHHYA/MO72e5z daQAn1pNhgo/sMIMYWGwk8AC1m/HpkgW =XYhC -----END PGP SIGNATURE----- ------------------------------ Message: 2 Date: Wed, 21 Jan 2009 02:44:50 -0800 (PST) From: scholbert <scholb...@web.de> Subject: Weird hardware mod ??? To: hardware@lists.openmoko.org Message-ID: <1232534690716-2191559.p...@n2.nabble.com> Content-Type: text/plain; charset=us-ascii Hi, after having a deeper look into the schematics of freerunner, i realized that most of the pins of the Glamo camera interface are physically accessible at the resistor networks RP1801..1804. This led me to a wicked idea: Solder some thin wires to the dedicated signals and use this interface for a camera module. I thought about ripping it off from another phone (e.g. Nokia 6600 or 6680) and attach it to the freerunner. Of course a kernel driver would also be needed. Are there any details known about this interface of the Glamo? Any source code available?? Any comments are welcome! scholbert -- View this message in context: http://n2.nabble.com/Weird-hardware-mod-----tp2191559p2191559.html Sent from the Openmoko Hardware mailing list archive at Nabble.com. ------------------------------ _______________________________________________ hardware mailing list hardware@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/hardware End of hardware Digest, Vol 10, Issue 15 **************************************** _______________________________________________ hardware mailing list hardware@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/hardware
