But just to correct – From the are abit deprecated interface in SGS, SGS2 and you will similiar patterns. You can use it to deal with modem directly from Desktop (undecided when the Pc is really personally conversing with modem otherwise to section of Android’s HALs, that is then talking-to modem, getting such. USB-UART multiplexer within the I9000 and you may S8500/S8530 are qualified to key cellular telephone MicroUSB port anywhere between AP jak sprawdziД‡, kto ciД™ lubi w paltalk bez pЕ‚acenia USB/UART and CP USB/UART. Area of the dealing with screen used in over designs are RPC as a result of oneDRAM common-memory city. Discover equipment like “dpram”, “onedram”, “modemctl” in kernel – talking about critical for right working out-of modem. No matter if RIL is utilizing During the instructions, it does publish them as a consequence of RPC. AP-CP UART union appears to be put simply for very early booting stage (at least inside the I9000 and you can S8500, have not analysed I9100 however, imagine that’s similiar)
Ad1. There might be zero real capacity to communicate with modem myself to the SGS2 and at responses you are getting SS (Advanced Cellular Subscriber Software – RTOS dealing with Qualcomm’s CP)
Ad4. These datasheets is very safeguarded secrets from companies. Just solitary, unfinished manuals drip away from Qualcomm, not really helpful. Plus AP-CP RPC method is actually exclusive regarding Samsung, they had AMSS supply regarding Qualcomm and they are incorporating their very own people truth be told there.
Oh sure, We offered Qualcomm while the example, but is CP for the SGS2 Qualcomm? It wasn’t QC tool towards the SGS1 but tbh it can be very signed source.
Whenever you are AP-CP low-level process is opensource (there are it inside the dpram/onedram/modemctl motorists inside the kernel), sophisticated of these layer – accumulated with the sec-RIL, isn’t. AP-CP method varies between I9000 and you can S8500 (standard style continues to be the same, simply it’s been rewriten so packet sizes and formations are different), but when you are interested – our company is carrying out opensource RIL for S8000/S8500/S8530/S8600 unit series, designed to focus on Android os ports for them – (branch fresh-MochaIPC)

Provided the modem works well, there’s nothing must enjoy with the specifics of how ril correspond with modem, but when brand new modem does not work whilst is always to (Inside my case it would not sign in towards only one specific mobile operator), an on order that do a manufacturing plant reset of your modem could be helpful

Your From the is actually deprecated is no magic, however the reality (no less than according to particular firmware gurus) is the fact it can still be a bit through to the OEM’s get reduce new (AT) reliance of its magic and you will crappy exclusive firmware, very often have to be backwards suitable.
Off whether or not I’m talking-to AP otherwise CP. You are probably true that I’m talking to AP as a consequence of HAL. At the very least off SGS2 take off diagram, UART-step three is in the AP, but linked to a level-shifter from the PMIC (however on a single SoC), that’s therefore linked to the BP UART-X. (There isn’t an idea as to the reasons this is done very.) Therefore nevertheless they look that AT’s is interacting with their destination, compliment of specific abstraction coating, and therefore sung Motorists rather than from a location (phone) terminal shells.
Issue was, what happens if we attempt to use the Bada key, to enter ServiceMode (SM) and permit the fresh new corresponding BP access? Nevertheless SM differs into the SGS and this choice is maybe not certainly offered. Yet not, discover:
[ Edit ] I found they! The selection of AP/BP union conclusion whenever hooking up their phone as the good USB customer, so you can a pc server, shall be yourself set in the newest PhoneUtil (PU) selection. Which kits the fresh new decisions of the cellular telephone when hooking up they to help you a pc, to be able to come across if or not you adore they to behave due to the fact an excellent Modem or PDA, into USB and you may/or UART vent. The new PU menu is different from the new ServiceMode selection.
