🥇OpenLinux ngati gawo la ma module a SIM7600E-H

Njira yopangira pulogalamu yokhazikika ndikuyiyika mu gawoli imapezeka pansi pa Linux ndi Windows. M'nkhaniyi tiwona mwatsatanetsatane momwe, pogwiritsa ntchito zitsanzo za SDK zomwe zaperekedwa SIMCom Wireless Solutions phatikiza ndi kuyika pulogalamu yokhazikika mu module.

Ndisanalembe nkhaniyi, mnzanga wina, yemwe anali kutali ndi Linux, adandifunsa kuti ndifotokozere momwe ndingapangire gawo langa la gawo la SIM7600E-H mwatsatanetsatane momwe ndingathere. Njira yowunika kupezeka kwa nkhaniyo inali mawu akuti "kuti ndimvetse."

Ndikukupemphani kuti mudziwe zimene zinachitika.

Nkhaniyi imawonjezeredwa ndikusinthidwa pafupipafupi

Kuwonetseratu

Nthawi zambiri, ma module olumikizirana ma cell amagwiritsidwa ntchito potumiza deta, kuyimba mawu, kutumiza ma SMS ndi zina zotero. Zonsezi zimachitika kudzera mu malamulo a AT otumizidwa kuchokera ku microcontroller yakunja. Koma pali gulu la ma module omwe amakulolani kuti mugwiritse ntchito ma code omwe atulutsidwa kunja. Nthawi zina, izi zimachepetsa kwambiri bajeti yonse ya chipangizocho, kukulolani kuti muyike microcontroller yosavuta (komanso yofanana) pa bolodi kapena kusiya zonse. Kubwera kwa ma module a LTE olamulidwa ndi Android kapena Linux OS ndi zida zawo zamphamvu, ndizotheka kuthetsa ntchito zilizonse zomwe zimapezeka kwa mapurosesa otchuka. Nkhaniyi ilankhula za SIM7600E-H, yoyendetsedwa ndi Linux OS. Tiwona momwe tingatsitsire ndikuyendetsa pulogalamu yomwe ingagwiritsidwe ntchito.

Munjira zambiri, nkhaniyi imachokera ku chikalata "SIM7600 Open Linux Development quide", koma zowonjezera zina, choyamba, Baibulo la Chirasha lidzakhala lothandiza. Nkhaniyi ithandiza omwe angoyamba kumene kuphunzira gawoli kumvetsetsa momwe angatsitse pulogalamu ya demo ndikupereka maluso ofunikira pantchito yotsatira.

Mwachidule za yemwe SIM7600E-H ndi

SIM7600E-H ndi gawo lomangidwa pa purosesa ya ARM Cortex-A7 1.3GHz yochokera ku Qualcomm, yokhala ndi makina opangira a Linux (kernel 3.18.20) mkati, omwe amatha kugwira ntchito ndi European (kuphatikiza Russian) frequency band 2G/3G/LTE yothandizira Cat. .4, yopereka liwiro lalikulu lotsitsa mpaka 150Mbps ndi liwiro lokweza mpaka 50Mbps. Zotumphukira zolemera, kuchuluka kwa kutentha kwa mafakitale komanso kupezeka kwa GPS/GLONASS navigation yomangidwa kumaphimba zofunikira zilizonse pakuyankhira kwamakono m'munda wa M2M.

Kachitidwe mwachidule

Module ya SIM7600E-H imachokera ku Linux opaleshoni system (kernel 3.18.20). Momwemonso, fayilo yamafayilo imamangidwa pamaziko a fayilo yolemba UBIFS (Unsorted Block Image File System).

Zofunikira za fayiloyi ndi izi:

amagwira ntchito ndi magawo, amakulolani kupanga, kuchotsa, kapena kusintha kukula kwake;
imawonetsetsa kulumikizidwa kwamtundu wonse wa media;
imagwira ntchito ndi midadada Yoyipa;
amachepetsa mwayi wa kutayika kwa deta panthawi yamagetsi kapena kulephera kwina;
kusunga zipika.

Kufotokozera kwatengedwa kuchokera pano, palinso kufotokozera mwatsatanetsatane za fayilo yotereyi.

Iwo. Mafayilo amtundu uwu ndi abwino kwa zovuta zogwirira ntchito za module komanso zovuta zamphamvu zomwe zingatheke. Koma izi sizikutanthauza kuti kusakhazikika kwa mphamvu kudzakhala njira yoyembekezeredwa yogwiritsira ntchito module; zimangowonetsa kutheka kwakukulu kwa chipangizocho.

Gwirizanani, mndandandawu ndi wochititsa chidwi komanso zindikirani: gawo la zotumphukira limagwiritsidwa ntchito kugwiritsa ntchito gawo ngati rauta. Iwo. Kutengera gawo loterolo, mutha kupanga rauta yaying'ono yomwe idzagawa intaneti kudzera pa Wi-Fi. Mwa njira, pali yankho lokonzeka lopangidwa lotchedwa SIM7600E-H-MIFI ndipo ndi miniPCIE khadi yokhala ndi gawo la soldered SIM7600E-H ndi zikhomo zingapo za mlongoti, imodzi mwa izo ndi mlongoti wa Wi-Fi. Komabe, uwu ndi mutu wankhani ina.

Lachitatu (osati tsiku la sabata)

SIMCom Wireless Solutions perekani mwayi kwa opanga kuti asankhe malo odziwika bwino a Linux kapena Windows. Ngati tikukamba za ntchito imodzi yomwe ingagwiritsidwe ntchito pa gawo, ndiye kuti ndibwino kusankha Windows, idzakhala yachangu komanso yosavuta. Ngati mapangidwe ovuta a mapulogalamu ndi kukonzanso kotsatira akuyembekezeredwa, ndibwino kugwiritsa ntchito Linux. Timafunikiranso Linux kuti ipange mafayilo otheka kuti alowe nawo mu gawo; makina enieni ndi okwanira kuphatikizira.

Zomwe mukufunikira sizipezeka kwaulere - SDK, yomwe mungapemphe kwa wogawa.

Kuyika zida zogwirira ntchito ndi module

Pambuyo pake, tigwira ntchito pansi pa Windows ngati OS yodziwika bwino kwa ogwiritsa ntchito ambiri.

Tidzafunika kukhazikitsa mapulogalamu ofunikira munjira zingapo zosavuta kuti tigwire bwino ntchito ndi gawoli:

GNU / Linux
Cygwin
Oyendetsa
ADB

Kuyika GNU/Linux

Kuti mupange pulogalamuyi, mutha kugwiritsa ntchito compiler iliyonse yogwirizana ndi ARM-Linux. Tigwiritsa ntchito SourceryCodeBenchLiteARM GNU/Linuxtranslater yomwe ikupezeka kuti titsitse pa kugwirizana.

Kuonetsetsa kuti zigawo zonse zaikidwa molondola, ine ndisiya zithunzi zochepa za ndondomeko yoyikapo. Kwenikweni, palibe chovuta pakuyika.

Kuonetsetsa kuti zigawo zonse zaikidwa molondola, ine ndisiya zithunzi zochepa za ndondomeko yoyikapo. Kwenikweni, palibe chovuta pakuyika.

Timavomereza mgwirizano wa laisensi
Tchulani foda yoyika
Timasiya zigawo zofunikira zosasinthika
Zisiyeni momwe zilili
Kangapo "Kenako", "Ikani" ndipo kwenikweni ndi momwemo

Kukhazikitsa Cygwin

Kupitilira apo, pakukulitsa, mudzafunika ma library ndi zofunikira kuchokera pazomwe zaperekedwa Cygwin. Chilichonse ndi chosavuta pano, mtundu waposachedwa wa Cygwin ukhoza kutsitsidwa kwaulere patsamba lovomerezeka la polojekitiyi; pa nthawi yolemba, mtundu wa 3.1.5 unalipo, womwe ndi womwe tidagwiritsa ntchito pokonzekera nkhaniyi.

Palibe chovuta pakuyika Cygwin, chinthu chokhacho chomwe muyenera kusankha ndi galasi pomwe woyikirayo amatsitsa mafayilo ofunikira, sankhani iliyonse ndikuyiyika, komanso mndandanda wazinthu zofunikira ndi malaibulale, ndikusiya malaibulale onse omwe alipo. zida zosankhidwa.

Kuyika kwa driver

Pambuyo polumikizidwa ndi PC, muyenera kukhazikitsa madalaivala. Izi zitha kupemphedwa kwa wogawa wanu (zovomerezeka). Sindikupangira kuti mufufuze nokha pa intaneti, chifukwa ... Zingatenge nthawi yambiri kuti tipeze zomwe zidayambitsa mkangano wa chipangizocho.

Pakati pa madoko osankhidwa tikuwona zotsatirazi:

Monga momwe mwawonera, palibe USB ADB pakati pa madoko omwe ali pazithunzi, izi ndichifukwa choti doko la ADB mu gawoli latsekedwa mwachisawawa ndipo muyenera kuyiyambitsa potumiza lamulo la 'AT+CUSBADB=1' ku AT. doko la gawo ndikuyiyambitsanso (izi zitha kuchitika ndi lamulo la 'AT + CRESET').

Zotsatira zake, timapeza mawonekedwe omwe tikufuna mu woyang'anira chipangizocho:

Tamaliza ndi madalaivala, tiyeni tipite ku ADB.

Kukhazikitsa ADB

Pitani ku tsamba lovomerezeka la Android Developer kugwirizana. Sititsitsanso Android Studio yayikulu; tikungofunika mzere wolamula, womwe ukupezeka kuti utsitsidwe kudzera pa ulalo wa "Download SDK Platform-Tools for Windows".

Tsitsani ndikumasula zomwe zasungidwa ku mizu ya drive C.

Zosintha Zachilengedwe

Mukakhazikitsa Cygwin, muyenera kuwonjezera njira ya Cygwin/bin/ pakusintha kwachitukuko (Classic Control Panel → System → Advanced system settings → Advanced → Environment Variables → System Variables → Njira → Sinthani) monga momwe zasonyezedwera pa chithunzi pansipa:

Momwemonso, yonjezerani njira yosungiramo zakale za ADB zomwe zatsitsidwa ndi zosatulutsidwa ku muzu wa drive C.

Dinani Chabwino kangapo ndikuyambitsanso kompyuta.

Mukayambiranso, mutha kuwona ngati ADB ikugwira ntchito moyenera potsegula mzere wolamula (Win + R → cmd) ndikulemba lamulo la 'adb version'. Timapeza zinthu monga izi:

Tiyeni tilumikize gawoli ku PC (ngati ilumikizidwa) ndikuwona ngati ADB ikuwona ndi lamulo la 'adb zida':

Zachitika, izi zimamaliza kasinthidwe ka kugwirizana kwa module ndipo tikhoza kuyambitsa chipolopolo kuti tigwire ntchito ndi module.

Kutsegula ndi kupanga SDK

Tsopano popeza tili ndi chipolopolo ndipo titha kuyamba kugwira ntchito ndi mzere wolamula wa module, tiyeni tiyese kupanga pulogalamu yathu yoyamba kuti tilowe mu module.

Anthu ambiri angakhale ndi vuto ndi izi! Chifukwa Gawoli limagwira ntchito pa Linux; kupewa kugundana mukamalemba ma code pansi pa Windows, ndi bwino kuphatikizira m'malo omwe amakhala - Linux.

Sitikhala mwatsatanetsatane momwe, pakalibe Linux komanso chikhumbo choyiyika pamakina anu, mutha kuyiyika pamakina enieni. Tidzagwiritsa ntchito VirtualBox, kukhazikitsa Ubuntu 20.04 (mtundu wapano panthawi yolemba) ndipo pansi pake tiyamba kugwira ntchito ndi ophatikiza, ma SDK, ndi zina zambiri.

Tiyeni tipite ku malo a Linux ndikutsegula zolemba zomwe talandira kuchokera kwa wogawa.
