However, any Linux based kernel are equipment founded, so there must be an effective way to keep in touch with one equipment. (I have no idea how exactly to work with RPC’s. )

A: Concur, however, HW hackers are excessively worried about acquiring the precise datasheets. Rather aim for an old/similar one that is readily available. The old device people need not altered That much, however, at the least it would be a-start.

Not hard locate destroyed, it required practically month or two knowing many of these anything. Supplies are messy – tune in to Makefiles, a few of drivers commonly even obtained during the. I9000 GB driver (it actually was reorganised, comparing in order to Froyo) erbread-samsung/drivers/misc/samsung_modemctl

You can find my implementation of SHP OneDram frames-protocol truth be told there, centered on I9000 GB driver – (it’s just not functioning but really – noone examined they)

As you can see – it’s just lowlevel software from delivering structures and you will couple parsers. Actual parsers and senders regarding frames come into libsec-ril.very library of system – you can discover they having IDA (I would suggest six.0+, it does deal with Had out of linux DLLs a lot better than earlier incarnations) and get booting modem, starting callbacks inside of dpram/modemctl, parsing and you may giving boxes and so on. Have fun.

I must state I’m fairly missing on the topic currently. I have discover eg blogs from the replicant opportunity a while back. Perhaps you get some helpful suggestions here.

I am the fresh new Replicant creator whom worked on Nexus S port while having did the job towards the aries (universe s, galaxy tab) products and you can had written many of one’s totally free RIL.

Modems with the Android os products is actually a wide website name. Mobile phones disagree with the numerous things, like: * modem chipset * modem firmware * transport modem AP * modem protocol * user-place combination (Android os RIL)

First thing ‘s the modem chipset. You’ll find plenty. As an example into the HTC phones, you’ll have those within the MSM otherwise QSD SoCs (which is somewhat unusual, modems aren’t tend to the main SoC) IIRC. On the almost every other gizmos, it will be an alternative chip attached to the SoC thru various transport steps.

I understand finest the outcome of recent Samsung mobile phones, including Nexus S, Galaxy S, Galaxy Case (basic gen), Universe S2, etc.

Truth be told there, you’ve got the modem, constantly a keen intel x-gold 6xx, that is wired for the SoC. Thus transportation is accomplished via serial line and you can/or some loyal RAM memory (perhaps not about fundamental sticks).

In the event a phone can have a similar modem wired (from the equipment peak) the same way, the new kernel motorists is going to be various other. That’s the question of nexus s and galaxy s. To your first you to, modem Rx/Tx which have AP is carried out via ioctls during galaxy s it is over via an excellent PHONET circle interface (svnet0). Therefore it is maybe not (and particularly into the Samsung mobile phones) simply an effective serial screen you could unlock having monitor: you must know exactly how it’s over and you will generate dedicated software to replicate that it (cf. the fresh new code for the libsamsung-ipc/devices/ which is unit-specific).

Thus after you’ve transportation set up, you must know about the protocol new modem talks. So it depends on the newest firmware the latest modem try powering. I know that the modem utilized in Nexus S is additionally utilized in some new iphone 4 (4G IIRC) nevertheless have a separate firmware and so speaks an alternative protocol. I suspect it to be Within to the new iphone whenever you are Nexus S talks a great samsung-certain modem method. It formulated you to protocol and rewritten the newest modem firmware to use it in place of At the or anything else. It process is oftentimes called “Samsung IPC Protocol” and we provides a totally free implementation of they during the libsamsung-ipc and you can samsung-ril.
