Anyone knows easy way to get number of GPIO pin to enable 3G? I have tried to toggle all of them on/off -- got result of reboot, vibration, light, etc. Most of pins generates just reboot or hungs...

 

[marc132]

The cat has no 3g

 

[datacompboy]

The cat has no 3g

but em86 has its connected to second USB host of CPU.

 

[datacompboy]

Have built uhci & ohci modules, new USB hosts appears fine.
After that i have toggled all GPIO pins to hi/low -- but no new USB device detected... something wrong with EM770 initialization... or i have missed something more
still trying to get 3G up ://

Der ursprüngliche Beitrag von 19:30 Uhr wurde um 20:33 Uhr ergänzt:

Get 3G up! Just pulled hight GPIO pins 171 and 172

Whoops! Correct PINs are 167 and 168 -- there delay ~5 second before it starts after pull both high.

 

[marc132]

great

 

[datacompboy]

So, to get 3G up, you should put modules: ehci-hcd.ko, ohci-hcd.ko, gpiotoggling.ko to /system/wifi/

And run as root (via adb shell):
insmod /system/wifi/ehci-hcd.ko
insmod /system/wifi/ohci-hcd.ko
insmod /system/wifi/gpiotoggling.ko
echo 167 > /sys/gpiotoggling/pin_on
echo 168 > /sys/gpiotoggling/pin_on

After that internal 3G module is UP.

gpiotoggling module you can grab here: https://github.com/datacompboy/gpio-toggling---linux-kernel-module
[eo]hci-hcd.ko are built from telechips 3.0.8 kernel.

 

[datacompboy]

Built new initramfs, with 3g module. Now it fully working and automatically enables 3G.
Now, android4 for me fully working -- i can use it as car navi

Full install procedure:
1. Install CatNova4Flash2707.rar
2. root it
3. put em86an4-3g.img to /sdcard/
4. adb shell flash_image boot /sdcard/em86an4-3g.img
5. put wifi-update.zip as update.zip to card, and install it via recovery OR just put its system/wifi/ contents to /system/wifi of tablet.
6. Reboot.

Now you have fully working internal 3G and fully working Wifi on EM86.

Klasse Arbeit!

Um für uns Cat Nova Besitzer einen Nutzen daraus ziehen zu können, fehlen nun folgende Informationen:

-Welches 3G modul ist verbaut?
-Wo bekommt man es preisgünstig her?

 

[datacompboy]

3G module are internally connected. Not sure is there in CatNova mini-pci-e connector inside, need to check your openings.
In EM86 there EM770 module installed, you can get it from aliexpress starting from ~30 usd.

It seems that is place for 3G module:

[dickenseck]

Ok!
That pic is from a Cat nova, that means there is no mini pci socket but its prepared for that.

So we need 3G-modul + a mini pci socket + craftsmanship?

 

[datacompboy]

looks so. when (and if) i'll open my em86, i'll see is there connector or just directly soldered its

 

[datacompboy]

You should also connect some antenna (not sure, is it on backplate printed ?) + you need SIM card holder. As i see, module doesn't have it internal. Maybe some kind of have.

 

[wolfstain]

I do not understand a thing, you mean 3g for internet browsing or mobile phone?

 

[datacompboy]

it should work for both. i'm using just mobile internet.

 

[datacompboy]

Pffr... Google doesn't helps... I have repacked SDNovaA4.zip with my kernel & modules, ZipSigner used to sign it; but recovery install fails "Signature verification failed"... what can be wrong?

 

[dickenseck]

Use update zip modifier from xda-board.

Since you also have em86, I have a question, you also happen the problem of recovery mode, I do not work the touch and so I can not go into the options, only happens in 4.0

 

[datacompboy]

the problem of recovery mode, I do not work the touch and so I can not go into the options, only happens in 4.0

there several users of JY8002 says about that problem.
right now i can't find any solution for recovery mode, but if you have adb working, can you show output of "dmesg" from 2.3 version (where touch working) and 4.0 version (where not) ?
needs dmesg from scratch boot, reboot tablet before gathering output please.
