Strato Pi CM - Strato Pi CM Duo
Chithunzi cha Raspberry Pi OS
Sfera Labs Srl ikhoza kusintha zomwe zanenedwa ndi mafotokozedwe azinthu nthawi iliyonse, osazindikira. Zambiri zamalonda pa web malo kapena zinthu zitha kusintha popanda chidziwitso.
Chonde tsitsani ndikuwerenga chikalata cha Sfera Labs Terms and Conditions chomwe chilipo: https://www.sferalabs.cc
Mawu Oyamba
Chikalatachi chikufotokoza za kukhazikitsidwa kwa Strato Pi CM kapena Strato Pi CM Duo yokhala ndi Raspberry Pi OS yoyikiratu ikagulidwa kuchokera ku Sfera Labs. Komanso imapereka chiwongolero choyambira mwachangu kuti mugwiritse ntchito chipangizo chanu mwachangu.
Kukonzekera kwa OS
Mtundu wa Raspberry Pi OS
Raspberry Pi OS Lite
Tsiku lotulutsa: Seputembala 22nd 2022
Dongosolo: 32-bit
Mtundu wa Kernel: 5.15
Mtundu wa Debian: 11 (mphindi)
Wogwiritsa
Dzina lolowera: pi
Mawu achinsinsi: rasipiberi
Networking
Kukonzekera kwa netiweki sikunasinthidwe kuchokera ku zosintha zake: DHCP imayatsidwa pa mawonekedwe a Efaneti (eth0) ndipo dzina la homuweki lakhazikitsidwa kuti "raspberrypi".
Pamanetiweki ambiri omwe ali ndi seva ya DHCP yomwe ilipo muyenera kufika pagawo ngati "raspberrypi.local".
SSH
Kufikira kwa SSH ndi kutsimikizika kwachinsinsi kumayatsidwa pa doko lokhazikika 22.
Kusintha kwa Strato Pi
Kernel module
Mtundu waposachedwa (panthawi yopereka) wa gawo la Strato Pi Kernel wayikidwa, wokonzedwa kuti ulowetse pa boot ndi mafayilo ake a sysfs opezeka kwa wosuta pi.
Zambiri zonse zikupezeka pa: https://github.com/sfera-labs/strato-pi-kernel-module
Mtengo wa RTC
Basi ya I²C ndiyoyatsidwa ndipo phukusi la "i2c-tools" ndi ntchito zosinthira za RTC ndi zolemba zimayikidwa.
Chifukwa chake OS imakhazikitsidwa kuti isinthe ndikugwiritsa ntchito tsiku ndi nthawi yosungidwa ndi RTC.
Kuti mumve zambiri onani bukhu la ogwiritsa ntchito.
Makhadi awiri a SD
Kuphimba kwa "sdio" kumayatsidwa, komwe kumafunikira pa Strato Pi CM Duo kuti mupeze khadi ya SD pabasi yachiwiri.
Kuti izi zitheke, mzere wotsatira wawonjezedwa ku /boot/config.txt: dtoverlay=sdio,bus_width=4,poll_once=off
Seri console
Linux serial console imayatsidwa mwachisawawa pa chipangizo cha ttyAMA0, chomwe chimalumikizidwa ndi mawonekedwe a Strato Pi CM's RS-485. Mtengo wa baud wakhazikitsidwa ku 115200.
Chifukwa chake mutha kulumikizana ndi kontrakitala yolumikizira kompyuta yanu ku mawonekedwe a RS-485 pogwiritsa ntchito, mwachitsanzo, adapter ya USB ndi pulogalamu iliyonse yolumikizirana.
Zindikirani kuti, chifukwa mawonekedwe a RS-485 hardware ndi theka-duplex (kutanthauza kuti mapeto onse sangathe kufalitsa nthawi imodzi) ndipo Linux console imafanana ndi khalidwe lililonse lomwe limalandira, kutumiza mofulumira kwa zilembo zingapo, monga poika lamulo lonse ku console, zingabweretse. m'malemba owonongeka njira zonse ziwiri.
Kuti muyimitse cholumikizira kuti mugwiritse ntchito mawonekedwe a RS-485 pazifukwa zina, tchulani Buku Logwiritsa Ntchito.
Yambani Mwamsanga
Yatsani
Lumikizani mapini a block +/- pamagetsi oyenera, okhala ndi 9-28 Vdc zotulutsa, zomwe zimatha kupereka osachepera 6W, kapena kupitilira apo ngati muli ndi zida zolumikizidwa ndi USB.
Onani zachidziwitso cha ogwiritsa ntchito kuti mumve zambiri zofunikira pamagetsi.
Yatsani magetsi ndikudikirira kuti unit iyambike.
Muyenera kuwona buluu ON LED ikuyamba kuthwanima, ndikutsatiridwa ndi nthawi zodutsana za kuthwanima kosasunthika komanso kosakhazikika. Kumapeto kwa ndondomeko ya boot TX LED idzawombera ndipo pamapeto pake, pafupifupi masekondi 30 kuchokera kumagetsi, ON LED idzakhalabe.

Kufikira kwadongosolo
Njira yosavuta yolumikizira dongosololi ndikuyilumikiza ku netiweki ndi ntchito ya DHCP ndikulowa kudzera pa SSH.
Lumikizani chingwe cha Efaneti ndikuwonetsetsa kuti mukuwona ma LED a padoko la Efaneti akugwira ntchito.
Gwiritsani ntchito pulogalamu yomwe mumakonda ya kasitomala wa SSH kuchokera pakompyuta yanu yolumikizidwa ndi netiweki yomweyo ndikugwiritsa ntchito "raspberrypi.local" ngati adilesi. Mwachitsanzo, kuchokera pa Linux terminal: $ ssh pi@raspberrypi.local
Ngati kulumikizana kwabwino, lowetsani mawu achinsinsi ("rasipiberi") ndipo mwakonzeka kugwiritsa ntchito Strato Pi CM.
Ngati kulumikizana sikukuyenda bwino, yesani ping "raspberrypi.local". Ngati gawolo liyankha, muyenera kuwona adilesi yake ya IP pamayankho a ping, kuti mutha kuyesa kugwiritsa ntchito IP iyi polumikizana ndi SSH, mwachitsanzo: $ ssh pi@192.168.1.13
Ngati simunathe kupeza adilesi ya IP ya chipangizocho, lowetsani rauta yanu, modemu, kapena gulu lowongolera la seva ya DHCP ndikupeza adilesi ya IP yomwe yaperekedwa ku Strato Pi.
Kapenanso gwiritsani ntchito pulogalamu ya scanner ya netiweki kuti mulembe zida zonse zolumikizidwa ndi netiweki ndikufufuza Strato Pi.
Mulimonsemo, iyenera kuwoneka pamaneti ngati board ya Raspberry Pi.
Ngati zonse zomwe zili pamwambazi zalephera kapena mulibe netiweki yolumikizidwa ndi DHCP yoti mugwiritse ntchito, mutha kuyesa kulumikiza Strato Pi CM ndi chingwe cha Ethernet molunjika ku doko la Ethernet la kompyuta yanu. Kutengera ndi kompyuta yanu OS ndi kasinthidwe ka netiweki mutha kufika pagawo monga tafotokozera pamwambapa.
Njira yomaliza ndiyo kupeza kontrakitala kudzera pa RS-485 serial interface monga tafotokozera pamwambapa. Kuchokera apa mutha kulowa ndikulemba dzina lolowera (pi) ndi mawu achinsinsi (rasipiberi) ndikuwunika adilesi ya IP ya chipangizocho pogwiritsa ntchito lamulo la "ifconfig".
Mutha kugwiritsa ntchito makinawo mwachindunji kudzera pa RS-485 serial console; sizosavuta kugwiritsa ntchito, koma zotheka.
Kugwiritsa ntchito
Mukalumikizidwa ndi chipangizochi mutha kuchigwiritsa ntchito ngati kukhazikitsa kwa Raspberry Pi OS kuti mukonze makonda anu ofunikira ndikuyika pulogalamu yanu.
Monga kuyesa mwachangu, yatsani kulemba kwa L1 LED: $ echo 1 > /sys/class/stratopi/led/status
