N900: ofonod segfaults

[pavelmachek]

(This may be bug in upstream ofonod).

After inserting modules, and providing symlink for ofonod:

root@devuan:/home/user/my/ofono/test# rmdir /dev/cmt
root@devuan:/home/user/my/ofono/test# ln -s /sys/bus/hsi/devices/n900-modem/ /dev/cmt
root@devuan:/home/user/my/ofono/test# ofonod -n -d

It segfaults:

I wonder if all the right options in the kernel are enabled. Perhaps we're missing something there?

[pavelmachek]

Not sure, it might be kernel. But from the log it seems that ofonod got quite far with the init.

There were bugs in upstream ofonod that prevented operation on N900, I'd suggest looking there first.

[MerlijnWajer]

OK - do you remember when? I recall I had ofono working on my n900 with Gentoo half a year ago or so. I can check the kernel and ofono version if that helps.

[MerlijnWajer]

I reproduced the issue on my N900. I saw this thread: https://github.com/postmarketOS/pmbootstrap/issues/520

Seems like we need to use the latest ofono master.

[MerlijnWajer]

Actually, ofono 1.22 should work.

[MerlijnWajer]

Our repos now have ofono 1.22 - it does not seem to segfault on start anymore. Can you try again?

[MerlijnWajer]

Actually, with nokia-modem probed, it seems to abort in the same way as before.

[MerlijnWajer]

When I probe like this: modprobe nokia-modem pm=1 ofono does not segfault. Our default cmdline sets pm=0 - not sure why.

@pavelmachek - I think it should work now?

[MerlijnWajer]

FWIW I used this setup: https://github.com/postmarketOS/pmbootstrap/issues/520#issuecomment-328076753

[MerlijnWajer]

I don't have a sim right now, but I believe these instructions should now just work: http://musicnaut.iki.fi/txt/nokia_modem.txt

[MerlijnWajer]

I have tested internet data, works. SMS, works. Started a phone call, other phone dialed. Didn't test any sound.

[pavelmachek]

I'm pretty sure sound will not work for voice call (libcmtspeechdata would be needed for that). If it does, I'll port ofone gui and we'll have usable phone.

[pavelmachek]

Thanks for your help. I'm currently on holidays, so I won't be able to test it soon.
