Now, if your modem handling software is utilizing RPC, just how is it reflected on Operating system top?

Still, one Linux situated kernel try unit founded, so there have to be a way to keep in touch with you to definitely tool. (We have no idea ideas on how to work with RPC’s. )

A: Concur, however, HW hackers usually are too-much concerned with obtaining the specific datasheets. Instead strive for an old/equivalent one that’s available. The outdated product drivers really need maybe not changed This much, however, at least it might be a-start.

Not difficult discover lost, it took me practically few months knowing all of these something. Supplies are dirty – tune in to Makefiles, some of people are not even accumulated inside the. I9000 GB driver (it was reorganised, contrasting in order to Froyo) erbread-samsung/drivers/misc/samsung_modemctl

Discover my implementation of SHP OneDram structures-method around, according to I9000 GB driver – (it’s just not operating but really – noone checked-out it)

Perhaps you have realized – it is merely lowlevel program out of sending structures and you can few parsers. Actual parsers and senders out of structures are located in libsec-ril.therefore collection from system – you might discover it with IDA (I would recommend six.0+, it will deal with Had regarding linux DLLs a lot better than earlier versions) and acquire booting modem, starting callbacks inside of dpram/modemctl, parsing and you may delivering boxes etc. Have a great time.

I want to say I am fairly missing on the topic already. I have hear about such as for example content during the replicant enterprise a little while ago. Perhaps you get some useful information truth be told there.

I’m the new Replicant creator whom labored on Nexus S port and just have performed the job with the aries (universe s, universe tab) equipment and you may blogged a majority of free RIL.

Modems to the Android os equipment was a wide website name. Mobile phones differ towards the many things, like: * modem chipset * modem firmware * transportation modem AP * modem method * user-area integration (Android os RIL)

To begin with is the modem chipset. You will find lots of. For instance into HTC mobile phones, you will have the people as part of the MSM otherwise QSD SoCs (which is slightly strange, modems aren’t commonly a portion of the SoC) IIRC. To the other equipment, it will likely be another chip connected to the SoC thru individuals transport measures.

I’m sure top the scenario of the latest Samsung phones, like Nexus S, Universe S, Universe Loss (first gen), Universe S2, etcetera.

Here, there is the modem, constantly an intel x-silver 6xx, which is wired on the SoC. So transport is performed through serial range and/otherwise certain dedicated RAM memory (not from the main sticks).

In the event a phone might have an identical modem wired (during the methods level) in the same way, this new kernel people is going to be different. That is the question of nexus s and you will galaxy s. On the very first one to, modem Rx/Colorado with AP is carried out through ioctls during galaxy s it’s complete through a great PHONET network screen (svnet0). So it’s maybe not (and particularly on Samsung cell phones) just good serial user interface you could discover which have display: you need to understand exactly how it’s complete and you can make loyal application to reproduce which (cf. the newest code for the libsamsung-ipc/devices/ that’s unit-specific).

So after you have transport set-up, you should know regarding the method brand new modem talks. So it hinges on the latest firmware the modem are powering. I understand that the modem utilized in Nexus S is even found in specific iphone 3gs (4G IIRC) nonetheless it features another firmware and thus talks a unique process. We believe that it is At with the new iphone 4 whenever you are Nexus S speaks a samsung-particular modem protocol. It invented that protocol and you will rewritten new modem firmware to use they rather than In the or other things. That it method might be entitled “Samsung IPC Protocol” and in addition we have a free of charge utilization of it inside the libsamsung-ipc and you will samsung-ril.
