GPRS drops on Froyo 201104 SD

[GoogleCodeExporter]

I installed the development release of Froyo from 201104 to my SD-card.  I went 
ahead and installed Google's apps as well, as per these instructions:
http://groups.google.com/group/android-on-freerunner/browse_thread/thread/55b8cc
d71f81b50a

GPRS will work some of the time.  Usually, it will drop off even though the 
icon remains in the status bar.  Here are some logcats I was able to extract 
after GPRS dropped off.

For what it is worth, I am connected via Vodafone's network here in Berlin, 
although my provider is 1und1.

So I was wondering if I could reproduce this issue on a fresh install, and sure 
enough I can.  Here is a logcat after a fresh install.

This time (however), I did not get a the GPRS icon in the status bar.

It occured to me that I had mistakenly installed HTC apks that came with the 
google apps pack.  So, I did a clean install ( without the HTC apks and without 
the PassionQuickOffice ).  I will do some more testing and get back to you.

It seems that every time I do an install onto SD, it will run fine for several 
boots, but at some point ( about after a few weeks ), internet connectivity 
will become so rare that the phone is pretty much unusable as an internet 
device.

Here is a logcat I took today, having installed from 
android-on-freerunner-cupcake-sd-stable-201101.tar.gz several weeks ago.  The G 
icon will appear promptly after entering my pin, but the browser will be unable 
to connect to the internet.

Your logcat does not show anything suspicious, except for this:

W/pppd ( 1020): Could not determine remote IP address: defaulting to I

I'm not sure if this is the symptom or the problem itself.

Obviously, your provider can not be contacted when the remote IP is set to I. 
This should be something like 10.64.64.64, which is the typical default. The IP 
addresses are handled in the source file ipcp.c. Try changing the value of the 
parameter used in ipcp.c, in function ipcp_up(f). I could not locate the .h 
where the actual value is defined.

If this way you are able to connect, it is a software problem.

On the other hand, are you able to connect with GPRS using another phone, but 
using same SIM and GRPS credentials and APN settings? (Trying to rule out 
you've hit your data limit).

Keep us posted.

Any proceedings here? I also have a very unstable GPRS connection. Most of the 
time i cannot get a connection at all.
Trying to execute '/system/etc/ppp/init.gprs-pppd debug file 
/data/ppp/options.gprs' writes the attached lines to logcat.

I can rule out the theory that I have reached my data limit, for two reasons: 
1) I have a flat rate on data, 2) GPRS works fine if I boot into the (really 
old) cupcake operating system on the internal flash.

Have you looked into the default value handling in ipcp_up (ipcp.c)?

I looked at the code, but my C(++?) is not strong enough that I knew what I was 
doing.

I guess I could try installing onto the internal flash.  I have been trying to 
avoid that, as I have been trying to maintain at least one boot option that is 
functional.
