But just to correct – On is actually abit deprecated software inside the SGS, SGS2 and you will similiar designs. It can be used to handle modem right from Pc (not sure in the event that Pc is truly directly talking to modem otherwise so you can section of Android’s HALs, that’s following talking-to modem, to possess such as for example. USB-UART multiplexer during the I9000 and you will S8500/S8530 is actually qualified to button mobile phone MicroUSB vent between AP USB/UART and CP USB/UART. Part of the dealing with interface used in more than habits try RPC as a result of oneDRAM shared-memory city. Discover equipment such as for example “dpram”, “onedram”, “modemctl” when you look at the kernel – speaking of critical for right operating out-of modem. Regardless of if RIL is utilizing At the instructions, it can posting them courtesy RPC. AP-CP UART connection appears to be made use of simply for very early booting phase (at the very least from inside the I9000 and quizy outpersonals you may S8500, haven’t analysed I9100 but guess that is similiar)

Ad1. There is certainly no real capability to keep in touch with modem directly into SGS2 at solutions you will get SS (Cutting-edge Cellular Subscriber Software – RTOS focusing on Qualcomm’s CP)

Ad4. This type of datasheets is actually really protected gifts off firms. Merely single, partial manuals drip out of Qualcomm, not even beneficial. As well as AP-CP RPC method is exclusive out-of Samsung, they got AMSS source out-of Qualcomm and are adding their own people around.

Oh sure, I gave Qualcomm because example, but is CP into the SGS2 Qualcomm? It wasn’t QC unit toward SGS1 however, tbh it can be most finalized origin.

If you’re AP-CP low-level process is actually opensource (there are it into the dpram/onedram/modemctl vehicle operators when you look at the kernel), excellent of these covering – gathered into the sec-RIL, is not. AP-CP protocol varies ranging from I9000 and you will S8500 (general design remains the exact same, just it’s been rewriten therefore package versions and structures are different), but when you need it – we’re doing opensource RIL to own S8000/S8500/S8530/S8600 device series, designed to work with Android os ports for them – (part fresh-MochaIPC)

Provided new modem works well, discover absolutely nothing have to look with the information on just how ril keep in touch with modem, however when the modem can not work because is always to (In my case they would not sign in for the one specific mobile operator), a from the order that may would a factory reset of modem will be of good use

That the Within are deprecated is no wonders, nevertheless the facts (at the very least considering specific firmware specialist) is that it does still be sometime until the OEM’s can get rid of the fresh new (AT) reliance of their secret and you may bad proprietary firmware, very often have to be backwards compatible.

Out-of if or not I am talking-to AP otherwise CP. Maybe you are true that I’m talking to AP as a result of HAL. About from SGS2 take off drawing, UART-3 is within the AP, but connected to an even-shifter about PMIC (still for a passing fancy SoC), which is consequently attached to the BP UART-X. (There isn’t an idea as to why this is accomplished very.) Therefore nevertheless they check the AT’s was interacting with their attraction, because of some abstraction covering, and that sung Vehicle operators and never regarding a district (phone) critical shells.

Issue are, what the results are when we just be sure to utilize the Bada key, to enter ServiceMode (SM) and enable the fresh new involved BP availability? However the SM is different to your SGS which choice is maybe not clearly readily available. Although not, there was:

[ Revise ] I found they! The selection of AP/BP relationship decisions whenever linking their phone once the an effective USB client, so you can a pc machine, should be yourself devote the fresh PhoneUtil (PU) selection. Which sets the new decisions of cellular phone whenever connecting they to a computer, so that you can find if or not you like it to do something once the a beneficial Modem or PDA, for the USB and you may/otherwise UART vent. The fresh new PU diet plan is different from the newest ServiceMode eating plan.
