Now, should your modem dealing with software is utilizing RPC, exactly how is this shown at the Os height?
However, any Linux situated kernel was unit centered, so there must be an easy way to correspond with that equipment. (I’ve no clue how-to manage RPC’s. )
A: Concur, however, HW hackers usually are excess worried about getting the direct datasheets. Alternatively aim for a classic/comparable one that’s available. The old product drivers need maybe not changed This much, however, at the least it could be a start.

Not hard to find missing, it required practically couple of months understand all of these one thing. Present are extremely messy – listen to Makefiles, a number of drivers are not actually collected during the. I9000 GB driver (it actually was reorganised, contrasting to help you Froyo) erbread-samsung/drivers/misc/samsung_modemctl
You will find my personal implementation of SHP OneDram structures-protocol here, based on I9000 GB driver – (it’s just not functioning but really – noone checked out they)
As you care able to see – it’s merely lowlevel screen away from giving structures and you can partners parsers. Genuine parsers and you can senders away from structures have been in libsec-ril.so collection regarding system – you can unlock it having IDA (I will suggest six.0+, it can manage Got away from linux DLLs a lot better than previous versions) and get booting modem, setting-up callbacks inside dpram/modemctl, parsing and you can delivering boxes and stuff like that. Have a great time.

I want to state I’m rather shed on the topic already. I’ve learn about such as posts on replicant project sometime before. Perchance you get some helpful tips around.

I’m this new Replicant developer who done Nexus S vent and get performed work to your aries (universe s, galaxy loss) gizmos and you can blogged a majority of totally free RIL.
Modems with the Android devices is actually an extensive domain. Mobile phones disagree to the many things, like: * modem chipset * modem firmware * transportation modem AP * modem method * user-place integration (Android os RIL)
The initial thing ‘s the modem chipset. There are a lot of. By way of example on HTC mobile phones, you should have those within the MSM or QSD SoCs (that is slightly strange, modems aren’t often a portion of the SoC) IIRC. To the other gizmos, it should be yet another chip attached to the SoC through individuals transportation procedures.
I understand ideal the outcome of the latest Samsung cell phones, eg Nexus S, Universe S, Universe Case (earliest gen), Galaxy S2, etcetera.
Around, you have the modem, constantly an enthusiastic intel x-silver 6xx, that’s wired for the SoC. Very transportation is accomplished through serial range and you can/otherwise some dedicated RAM memory (perhaps not on the fundamental sticks).
In the event a telephone may have an equivalent modem wired (at the knowledge top) 
the same exact way, new kernel people are going to be additional. This is the matter of nexus s and you may universe s. For the earliest one to, modem Rx/Texas with AP is performed thru ioctls while on galaxy s it’s done via a great PHONET circle screen (svnet0). So it is perhaps not (and particularly into Samsung mobile phones) simply a beneficial serial software you could open with monitor: you must know just how it’s over and you can create loyal software to reproduce that it (cf. new password into the libsamsung-ipc/devices/ that’s device-specific).
Very once you have transport set-up, you need to know towards method the fresh modem talks. It depends on the new firmware the new modem is actually powering. I am aware your modem included in Nexus S is also utilized in some iphone (4G IIRC) it keeps a different firmware and thus speaks a separate protocol. We suspect it to be From the into the iphone while you are Nexus S speaks a beneficial samsung-specific modem protocol. It created one to method and rewritten the new modem firmware to use it as opposed to At otherwise anything else. This protocol can be entitled “Samsung IPC Protocol” therefore have a totally free utilization of they inside libsamsung-ipc and samsung-ril.
