But just to improve – At the are abit deprecated user interface inside SGS, SGS2 and you will similiar activities. It can be used to manage modem directly from Desktop (not sure if Desktop computer is actually yourself speaking with modem or to part of Android’s HALs, that’s then talking to modem, getting for example. USB-UART multiplexer when you look at the I9000 and S8500/S8530 was competent to switch cellular telephone MicroUSB vent ranging from AP USB/UART and you may CP USB/UART. An element of the controlling software utilized in significantly more than patterns try RPC compliment of oneDRAM shared-memory town. You can find devices including “dpram”, “onedram”, “modemctl” into the kernel – talking about critical for best doing work away from modem. Even when RIL is utilizing At the instructions, it does send her or him courtesy RPC. AP-CP UART union is apparently put only for early booting phase (at the very least inside the I9000 and you will S8500, haven’t analysed I9100 however, suppose that is similiar)

Ad1. There may be zero real capability to correspond with modem really towards SGS2 and at solutions you’re going to get SS (State-of-the-art Cellular Customer Application – RTOS working on Qualcomm’s CP)

Ad4. Such datasheets are really protected gifts off manufacturers. Just single, unfinished manuals drip of Qualcomm, not really useful. And AP-CP RPC process is exclusive off Samsung, it got AMSS source away from Qualcomm consequently they are incorporating the individual people here.

Oh yes, We offered Qualcomm as analogy, it is CP into the SGS2 Qualcomm? It was not QC tool to the SGS1 however, tbh it is quite most signed supply.

If you are AP-CP low-level method are opensource (there are they from inside the dpram/onedram/modemctl vehicle operators from inside the kernel), advanced of this level – built-up on sec-RIL, is not. AP-CP method differs between I9000 and you may S8500 (general build continues to be the exact same, merely it has been rewriten therefore package designs and you may formations try different), but if you want it – the audience is undertaking opensource RIL to have S8000/S8500/S8530/S8600 device series, designed to work with Android slots in their mind – (department fresh-MochaIPC)

As long as new modem is very effective, there’s nothing need certainly to search toward information on just how ril communicate with modem, but when the brand new modem can not work whilst would be to (During my situation they refused to sign in towards the one certain cellular operator), an at the command that can do a factory reset of one’s modem could well be beneficial

That the At are deprecated isn’t any miracle, but the facts (about based on some firmware gurus) would be the fact it does still be sometime before OEM’s may reduce the fresh new (AT) dependence of their magic and crappy exclusive firmware, very often need to be backwards suitable.

Off whether or not I am conversing with AP otherwise CP. Maybe you are correct that I am talking-to AP using HAL. At least regarding SGS2 cut-off diagram, UART-step 3 is in the AP, however, connected to a level-shifter regarding the PMIC (however on a single SoC), which is therefore attached to the BP UART-X. (I don’t have an idea why this is done thus.) Thus nevertheless it hunt the AT’s are getting together with their appeal, owing to certain abstraction covering, and that sung Drivers and not of an area (phone) terminal shells.

Issue are, what are the results whenever we try to use the Bada key, to enter ServiceMode (SM) and permit brand new associated BP supply? Although SM differs for the SGS hence choice is not clearly offered. However, you will find:

[ Modify ] I came across they! The selection of AP/BP connection conclusion whenever hooking up the mobile phone as good USB visitors, in order to a pc host, is yourself devote the newest PhoneUtil (PU) eating plan. That it establishes the fresh conclusion of your own cellular phone when hooking up it so you can a computer, to be able to come across whether you like it to do something once the a Modem or PDA, toward USB and you will/otherwise UART vent. The newest PU eating plan is different from the fresh new ServiceMode eating plan.
