Guest rebel1 Posted October 13, 2011 Report Share Posted October 13, 2011 Cass, Rebel1. Newbe5 - are we likely to see an Update4 anytime with these new HDMI, Wifi/BT, GPS and Tethering changes? Yes, of course. I work on it, but we are all little bit busy in the moment. :rolleyes: It should be released soon. :D rebel1 Link to comment Share on other sites More sharing options...
Guest rebel1 Posted October 13, 2011 Report Share Posted October 13, 2011 Well, i am still unable to make a working version of abtfilter... Butt i did other things ... >Added proper power management to the wifi driver. Now it is able to power up/down the adapter, so this should solve some issues regarding wifi connections that stop working after suspend... I also wrote a new libgps. This new library allows to use the internal GPS part of the UTMS modem EM770W as a location source ... I have tested it, and loads, seems to work ... Well, thats all for now, Eduardo Great work at all as anytime. ;) Unfortunately i run out of time in the moment, but i have tested your libgps. It works, but i have 2 issues with it: 1. It seems that HC don´t see the gps data, it doesnt work for me when i can see valid nmea data on ttyUSB3 2. after suspend, the gps ports changes to ttyUSB6 and 7, but i know this problem, because i wrote a little app that works with the mock locations api and when the serial lines are not closed before suspend they will be enumerated as 6 and 7 ;) rebel1 Link to comment Share on other sites More sharing options...

When the GPS suspends, the UTMS/GPS module is powered down, appearing as if it was unplugged from the USB internal port where it is connected to. But the GPS library does not close the ttyUSB3/4 ... as it does not get a notification on the suspension. Now, when the system resumes, the GPS is powered up again, and then , udev creates new ttyUSB for it, as the previous ones are still "in use" ... There are 2 possible solutions to it: Either avoid GPS suspension when the system goes to the suspend state (echo -e 0\n > /sys/devices/platform/shuttle-pm-gps/keep_on_in_suspend ...) or, try to detect the removal situation and release the ports by closing the ttyUSB files. I am not sure on the right approach to follow... Would it be more correct to leave the GPS on while system suspended ... ? , or it would be better to turn it off? -- Opinions? Regarding HC not seeing the data... well, i'll try to figure out why... Perhaps something else has to be done to make it work... Eduardo Link to comment Share on other sites More sharing options...

Now, after resuming, things are OK (the GPS ttyUSBx are only used when not suspended... And the GPS is open only when there is an active app using it... I think it should work right now... At least HC callbacks are called with GPS data ...

Guest ejtagle Posted October 16, 2011 Report Share Posted October 16, 2011 Well, i found some very interesting information on the AR6002 chipset... Seems it supports Wifi hotspot mode, after all ;) -- And we don't need special fw for that. The 2.2 series driver is supporting AP mode... The only thing remaining would be to implement some ioctls (required by Android) on the Atheros wifi driver that call the custom Atheros ioctls (on the same driver!) to enable and disable AP mode... Attached something i found about the Atheros SDK (yes, documentation! ) :D Regards. EduardoAR6000 Family Programmer\'s Guide v2.2.pdf Link to comment Share on other sites More sharing options...
Guest ejtagle Posted October 19, 2011 Report Share Posted October 19, 2011 Well... I have done some more experiments. I can confirm that the Atheros Wifi with the driver we have (2.2.1.151) supports AP mode. I was able to activate it by doing a: insmod ar6000.ko fwmode=2 To enable AP mode (AP=Access Point, Wifi Hotspot) And then doing the steps outlined in the PDF to configure the AP To return to normal STA mode (Wifi station) rmmod ar6000 insmod ar6000.ko (you don't need the fwmode command, as it defaults to 1, and 1 is STA mode Regards, Eduardo Link to comment Share on other sites More sharing options...
Guest ejtagle Posted October 24, 2011 Report Share Posted October 24, 2011 Well, after some extra work, i found out that we can use Gingerbread sources to rebuild the netd daemon with special support for Atheros, something that is required to properly support AP mode with Atheros AR6002. That, coupled to the latest Wifi driver i already posted, and some modifications to the init.rc startup script to allow required services to be started up, finally allowed us to enable Wifi AP mode. That, added to the my previous post of mods to the kernel to support USB RNDIS wired tethering, finally allowed us to claim that the HC3.2 is feature complete and all Vega features are supported! I attached the required mods to enable Wifi AP mode, and the source code of the netd daemon ...

So, PEAP should be possible: http://ubuntuforums.org/showthread.php?t=249654 . I have no access to a PEAP network (and don't plan to setup one!) , but, using root explorer, you should check Android is creating a proper wpa_supplicant.conf (in the /etc/ folder... i can't recall exactly where it is stored, but you will find it) ...

Cass67 told me about wpa_suplicant, and thanks to him i know a little bit about it, just confirmed everything i know, looking at the link you gave me. The problem was that Vegacomb was not saving correctly the 2nd authentification phase (i use MVSCHAP V2) and (of course) it was not saving it on the wpa_supplicant file. Anyway, i will wait until your wifi update gets a ZIP release, because i don't know how to get it on the tablet(maybe is easy, i have basics knowledge of linux), once i get it i will try to fix it with you (if you want to, of course), because i actually have access to EAP networks. Or maybe is already fixed with your new modifications. Well, i have to say, Wifi EAP use to work on Vegacomb 1.7 so, is there anyway i can mix the wifi libraries or the wifi files with Vegacomb 3.2? or we lost compatibilty because Vegacomb 3.2 is on another kernel? P.D: Gracias por todo lo que haces, que sepas que aqui tienes un admirador. Me gustaria poder manejar el SDK de Android como lo dominas tu. Actualmente sé bastante del lenguaje Java y ahora estoy adentrandome en C y Linux (estudio Informatica) , tarde o temprano me gustaria empezar a hacerme mis cositas con el SDK o modificar el kernel o modificar librerias, añadir funciones, etc...

Guest mrz_hun Posted October 26, 2011 Report Share Posted October 26, 2011 Hi Guys! Can someone please take a look at the touchscreen drivers for Vegacomb and compare it to the kernel source released for the Advent Vega? Perhaps find out what the differences might be? I'm sure something is different, because myself and lots of others are suffering from touchscreen problems, which disappear when going back to moddedstock v2 and doing a recalibration. I would be willing to do beta testing for any modifications you might throw at me, because I would like to use Honeycomb VERY much, but this touchscreen problem is preventing me from using it. Unfortunately I can't even return my POV Mobii Tegra, because the problems doesn't happen on the official (crap) firmware (this is why I think it's a Honeycomb driver issue). Eduardo: I remember that the parameter for the Command 0x13: Mass Production Calibration for auto-tune is 0 in the original driver, and 1 in VegaComb. Can this be a problem? Is the Command 0x1C: Auto Tune Function used now? Can this be a problem? I think CDC means clock domain crossing in the IT7260 pdf. Thanks to anyone for any help.

Guest Scanno Posted October 31, 2011 Report Share Posted October 31, 2011 (edited) Hi all, Eduardo has made a lot of very good improvements to the kernel of the vega / mobii. As far as i can see there is no repository where all the changes are. Perhaps it would be a good idea to put these changes on github or something simular. If this is already the case then please ignore this. I gues a central reposotory of the kernel and drivers would make it easier for rom developers to include these important improvements in their roms.

(Not saying anybody should, or we deserve it... Just asking politely) I wish i have the knowledge to build the kernel with all the changes posted here. But to answer your question. On tabletroms there is a thread where people are trying to improve VegaComb. The upcomin version will have the updated wifi driver with the filter, so the wifi / bluetooth problem when using both is solved. They are also trying to build the kernel with all the patches. So if there are people who can help them there, i guess that would be appriciated :-) Also a good guide how to build the kernel and drivers and/or a good repository could help. With a good guide perhaps even i can build the kernel. I mean if i can setup a good cross-compile enverinment to build everything on my ubuntu box and there is a good working configure script it should not be very hard to build. Then knowing how to make the kernel image ..... I guess the following could help: - Create a github respository (public) with all the sources and patches - Guide how to build the kernel and drivers (do we need a cross-compile environment, config of the kernel, making an image) - Someone to maintain the repository - preferrable more rhen one person - This way it us easier to maintain the kernel and driver for the vega - one stop shop.

Building the kernel itself is not so difficult. You just get the latest NVidia kernel for the Tegra (11.2.13) and apply the patches i supplied. You also need the config file with all the features required (you can pull it from a running vega) ... But much better to use the one i provided ... And then you need the Android NDK , setup some environment variables... And you can compile it. It is not a big deal ;) Link to comment Share on other sites More sharing options...

You are not using the right base kernel. Either use nvidia 11.2.13 (http://nv-tegra.nvid...70cf169f8cb223f) . or just use https://github.com/rebel1 , but don't forget to apply the patches i did, as rebels 11.2.13 is not completely up to date. As a convenience, i attached all my latest patches to the kernel, so you don't have to start digging to find out the latest versions ... Eduardo PS: Please, dont forget to enable RNDIS USB gadget support, as that support is not enabled in VC, but would allow tethering via USB! Also, the other thing that can be adjusted (in board-shuttle.h) is the amount of memory dedicated to the GPU. More GPU mem means less main memory. Flash seems to require 128MB at least, otherwise the browser crashes with complex Flash content based pages. But, also the browser crashes if running out of main memory, so this is a complex game and tradeoff... Also, you could include the libgps i posted at post 729, that should allow to use the internal GPS present on EM770W 3G modem... No promises it will work, but it was my best attempt to do it ...
