OpenLinux sechikamu cheSIM7600E-H modules

Iyo nzira yekugadzira tsika yekushandisa uye kuiisa mumodule inowanikwa pasi peLinux neWindows masisitimu anoshanda. Muchikamu chino tichatarisa zvakadzama kuti sei, tichishandisa mienzaniso kubva kuSDK yakapihwa SIMCom Wireless Solutions kuunganidza uye kurodha tsika yekushandisa mune module.

Ndisati ndanyora chinyorwa ichi, mumwe wevandaizivana naye, ari kure nekugadzira Linux, akandikumbira kuti ndiuye kunyaya yekutsanangura maitiro ekugadzira yangu yekushandisa yeSIM7600E-H module mune zvakadzama sezvinobvira. Chiyero chekuongorora kuwanikwa kwemharidzo yezvinyorwa yaive mutsara wekuti "kuti ndinzwisise."

Ndinokukoka kuti uzive zvakaitika.

Nyaya yacho inogara ichiwedzerwa uye inovandudzwa

Prelude

Kazhinji, mamodule ekutaurirana anoshandiswa chete kutumira data, kufona kwezwi, kutumira kweSMS nezvimwe zvakadaro. Zvese izvi zvinoitwa kuburikidza neAT mirairo inotumirwa kubva kune yekunze control microcontroller. Asi pane chikamu chemamodule chinokutendera kuti uite tsika kodhi yakatakurwa kubva kunze. Mune zvimwe zviitiko, izvi zvinoderedza zvakanyanya bhajeti remudziyo, zvichikutendera iwe kuti uise iri nyore (uye yakaenzana bhajeti) microcontroller pabhodhi kana kuisiya zvachose. Nekuuya kweLTE modules inodzorwa neAroid kana Linux OS uye zviwanikwa zvavo zvine simba, zvinokwanisika kugadzirisa chero mabasa anowanikwa kune akakurumbira processors. Ichi chinyorwa chichataura nezve SIM7600E-H, inodzorwa neLinux OS. Isu tichatarisa maitiro ekudhawunirodha uye kumhanyisa application inogoneka.

Nenzira dzakawanda, zvinyorwa zvinobva pagwaro "SIM7600 Vhura Linux yekuvandudza quide", asi zvimwe zvekuwedzera uye, kutanga kwezvose, shanduro yeRussia ichave yakakosha. Chinyorwa chichabatsira avo vari kutanga kugona moduru kunzwisisa nzira yekurodha demo application uye nekupa hunyanzvi hunodiwa hwebasa rinotevera.

Muchidimbu nezve SIM7600E-H ndiani

SIM7600E-H imodule yakavakirwa paARM Cortex-A7 1.3GHz processor kubva kuQualcomm, ine Linux inoshanda system (kernel 3.18.20) mukati, inokwanisa kushanda neEuropean (kusanganisira Russian) frequency band 2G/3G/ LTE inotsigira Katsi. .4, ichipa kumhanya kwepamusoro kwekudhawunirodha kunosvika 150Mbps uye kumhanya kwekukwira kusvika ku50Mbps. Yakapfuma peripherals, tembiricha yeindasitiri uye kuvapo kweyakavakirwa-mukati GPS / GLONASS yekufamba inovhara chero zvinodikanwa zvechizvino modular mhinduro mumunda weM2M.

System overview

Iyo SIM7600E-H module yakavakirwa paLinux inoshanda sisitimu (kernel 3.18.20). Nekudaro, iyo faira system inovakwa pahwaro hweiyo Journaled faira system UBIFS (Unsorted Block Image File System).

Zvinhu zvakakosha zveiyi faira system zvinosanganisira:

  • inoshanda nezvikamu, inobvumidza iwe kugadzira, kudzima, kana kushandura saizi yavo;
  • inova nechokwadi chekurekodha kurongeka mukati mese media volume;
  • inoshanda neBad blocks;
  • inoderedza mukana wekurasikirwa kwedata panguva yekudzima kwemagetsi kana kumwe kutadza;
  • kuchengeta matanda.

Tsanangudzo yakatorwa kubva pano, panewo tsanangudzo yakadzama yeiyo faira system.

Avo. Iyi mhando yefaira sisitimu yakanakira mamiriro ekushandisa emodule uye zvinogona kuitika zvine simba matambudziko. Asi izvi hazvireve kuti mamiriro emagetsi asina kugadzikana achave maitiro anotarisirwa ekushanda kweiyo module; inongoratidza kugona kukuru kwechishandiso.

ndangariro

Kugoverwa kwenzvimbo dzendangariro kunogadzirwa sezvizvi:

Pane nzvimbo nhatu huru dzekusimbisa:

ubi0:roots - verenga-chete uye ine Linux kernel pachayo
ub0:usrfs - inoshandiswa zvakanyanya kune chirongwa chemushandisi uye kuchengetedza data
ubi0:cahcefs - yakachengeterwa FOTA zvigadziriso. Kana iyo nzvimbo iripo isina kukwana kurodha iyo yekuvandudza, sisitimu inodzima mafaera asina kushandiswa uye nekudaro kusunungura nzvimbo. Asi nekuda kwezvikonzero zvekuchengetedza, haufanirwe kuisa mafaera ako ipapo.

Bvumiranai, iyo rondedzero inonakidza uye cherechedza: chikamu chemaperipheral chinoshandiswa kushandisa module se router. Avo. Kubva pane module yakadaro, unogona kuita router duku iyo ichaparadzira Indaneti kuburikidza neWi-Fi. Nenzira, kune yakagadzirira-yakagadzirwa mhinduro inonzi SIM7600E-H-MIFI uye i miniPCIE kadhi ine soldered SIM7600E-H module uye akati wandei mapini antenna, imwe yacho iWi-Fi antenna. Zvisinei, iyi inyaya yechinyorwa chakasiyana.

Chitatu (kwete zuva revhiki)

SIMCom Wireless Solutions ipa mukana kune vanogadzira kuti vasarudze yakajairika budiriro nharaunda yeLinux kana Windows. Kana isu tichitaura nezveimwe inogoneka application pane module, saka zviri nani kusarudza Windows, ichave nekukurumidza uye nyore. Kana iwe uchitarisira yakaoma dhizaini yekuvaka uye inotevera kukwidziridzwa, zviri nani kushandisa Linux. Isu tinoda zvakare Linux kuti iunganidze mafaera anogona kuteedzera kuti anotevera kurodha mumodule; muchina chaiwo wakakwana kuunganidza.

Zvaunoda hazviwanikwe pachena kuti udhawunirodhe - SDK, iyo yaunogona kukumbira kubva kumugovera wako.

Kuisa zvishandiso zvekushanda nemodule

Pano, tichashanda pasi peWindows seyo inonyanya kuzivikanwa OS kune vakawanda vashandisi.

Tichada kuisa software inodiwa mumatanho mashoma akareruka kuti ugozogona kushanda nemodule:

  1. GNU / Linux
  2. Cygwin
  3. Vatyairi
  4. ADB

Kupfuurirazve, kuti uvandudze, iwe unozoda seti yemaraibhurari uye zvishandiso kubva pane yakapihwa seti Cygwin. Zvese zviri nyore pano, iyo yazvino vhezheni yeCygwin inogona kutorwa mahara pawebhusaiti yepamutemo yeprojekiti; panguva yekunyora, vhezheni 3.1.5 yaivepo, ndiyo yatakashandisa pakugadzira zvinhu.

Iko hakuna chakaomesesa pakuisa Cygwin, chinhu chega chaunoda kusarudza igirazi kubva kwairi iyo inoisa inodhawunirodha mafaera anodiwa, sarudza chero imwe uye woiisa, pamwe neseti yezvishandiso uye maraibhurari, ichisiya ese aripo eraibhurari uye. zvishandiso zvakasarudzwa.
