Ukusuka kumbono wesoftware, ukusuka kwiRaspberry Pi CM 1/3 ukuya kwiRaspberry Pi CM 4S ayinabuhlungu, njengoko umfanekiso weRaspberry Pi (OS) kufuneka usebenze kuwo onke amaqonga. Ukuba, nangona kunjalo, usebenzisa i-kernel yesiko, ezinye izinto ziya kufuneka ziqwalaselwe ekuhambeni. Utshintsho lwe-hardware lukhulu, kwaye ukungafani kuchazwe kwicandelo elilandelayo.
Isigama
Isitaki semizobo yelifa: Isitaki semizobo esimiliselwe ngokupheleleyo kwi-VideoCore firmware blob ene-shim application programming interface evezwe kwikernel. Le yeyona nto isetyenzisiweyo kuninzi lwezixhobo zeRaspberry Pi Ltd Pi ukusukela oko yasungulwa, kodwa ngokuthe ngcembe ithatyathelwa indawo ngu (F)KMS/DRM.
I-FKMS: Ukusetwa kweMowudi yeKernel engeyonyani. Ngelixa i-firmware isalawula ihardware ekwinqanaba elisezantsi (ngokomzekeloample izibuko ze HDMI, Bonisa Ujongano Lothotho, njl.njl.), iilayibrari eziqhelekileyo zeLinux zisetyenziswa kwikernel ngokwayo.
I-KMS: Umqhubi weMode ye-Kernel epheleleyo. Ilawula yonke inkqubo yokubonisa, kuquka ukuthetha kwi-hardware ngqo ngaphandle konxibelelwano lwe-firmware.
I-DRM: UMlawuli woBonelelo oluNgqo, inkqubo engaphantsi ye Linux kernel esetyenziselwa ukunxibelelana neeyunithi zokusetyenzwa kwemizobo. Isetyenziswa ngokubambisana ne-FKMS kunye ne-KMS.

Ukwahluka ngokwasemzimbeni
I-Raspberry Pi CM 1, CM 3/3+, kunye ne-CM 4S ifom yefom isekelwe kwimodyuli encinci ye-modyuli ye-inline yememori (SODIMM) isinxibelelanisi. Oku kunika indlela yokuphucula ehambelanayo ngokwasemzimbeni phakathi kwezi zixhobo.
PHAWULA
Ezi zixhobo azinakusetyenziswa kwindawo yokukhumbula njengesixhobo seSODIMM.
Iinkcukacha zobonelelo lwamandla
I-Raspberry Pi CM 3 idinga iyunithi yonikezelo lwamandla ye-1.8V yangaphandle (PSU). I-Raspberry Pi CM 4S ayisayisebenzisi i-1.8V ye-PSU kaloliwe yangaphandle ukuze ezi zikhonkwane kwi-Raspberry Pi CM 4S azisadityaniswa. Oku kuthetha ukuba iibhodi ezisezantsi zexesha elizayo aziyi kufuna ukuba kufakwe umlawuli, okwenza lula ulandelelwano lwamandla. Ukuba iibhodi ezikhoyo sele zine-+1.8V PSU, akukho bungozi bokwenzeka kwi-Raspberry Pi CM 4S.
I-Raspberry Pi CM 3 isebenzisa inkqubo ye-BCM2837 kwi-chip (SoC), kanti i-CM 4S isebenzisa i-BCM2711 SoC entsha. I-BCM2711 inamandla okusebenza amaninzi akhoyo, ke iyenzeka, eneneni inokwenzeka, ukuba isebenzise amandla amaninzi. Ukuba oku kuyinkxalabo ngoko ukunciphisa umyinge wewotshi ephezulu kwi-config.txt kunganceda.
Injongo ngokubanzi I/O (GPIO) ukusetyenziswa ngexesha lokuqalisa
Ukubhucungwa kwangaphakathi kweRaspberry Pi CM 4S iqala kwi-interface ye-serial peripheral interface (SPI) kwimemori ye-elektroniki ecimekayo efundekayo kuphela (EEPROM) isebenzisa i-BCM2711 GPIO40 ukuya kwi-GPIO43 izikhonkwane; xa ukuqalela kugqityiwe i BCM2711 GPIOs zitshintshelwa kwi SODIMM isidibanisi kwaye ke ngoko iziphatha njenge Raspberry Pi CM 3. Kwakhona, ukuba uphuculo lwenkqubo ye EEPROM luyafuneka (oku akukhuthazwa) ngoko i GPIO pins GPIO40 ukuya GPIO43 ukusuka kwi-BCM2711 buyela ekudityanisweni kwe-SPI EEPROM kwaye ke ezi zikhonkwane zeGPIO kwi Isixhumi se-SODIMM asisalawulwa yi-BCM2711 ngexesha lokuphucula inkqubo.
Ukuziphatha kweGPIO kumandla okuqala
Imigca ye-GPIO ingaba nenqaku elifutshane kakhulu ngexesha lokuqalisa apho lingatsalwa phantsi okanye liphezulu, ngoko ke ukwenza ukuziphatha kwabo kungalindelekanga. Oku kungaziphathi kakuhle kunokwahluka phakathi kweCM3 kunye neCM4S, kunye nokwahluka kwebhetshi ye-chip kwisixhobo esifanayo. Kwiimeko ezininzi zokusetyenziswa oku akunasiphumo ekusetyenzisweni, nangona kunjalo, ukuba unesango le-MOSFET elincanyathiselwe kwi-tri-state GPIO, oku kunokubeka emngciphekweni nawaphi na amandla alahlekileyo abambe ii-volts kunye nokuvula nasiphi na isixhobo esiqhagamshelwe esisezantsi. Sisenzo esilungileyo ukuqinisekisa ukuba isixhathisi sokopha kwesango ukuya emhlabeni sibandakanyiwe kuyilo lwebhodi, nokuba kusetyenziswa iCM3 okanye iCM4S, ukuze ezi ntlawulo zecapacitive zophe.
Amaxabiso acetyisiweyo kwi-resistor aphakathi kwe-10K kunye ne-100K.
Iyakhubaza i-EMMC
Kwi-Raspberry Pi CM 3, i-EMMC_Disable_N ikhusela ngombane iimpawu ekufikeleleni eMMC. KwiRaspberry Pi CM 4S lo mqondiso ufundwa ngexesha lokuqalisa ukugqiba ukuba i-eMMC okanye i-USB kufuneka isetyenziswe ukuqala. Olu tshintsho kufuneka lubonakale kuninzi lwezicelo.
EEPROM_WP_N
Iibhutsi zeRaspberry Pi CM 4S ezivela kwi-EEPROM ekwibhodi ecwangciswe ngexesha lokwenziwa. I-EEPROM inombhalo okhuselayo onokuthi unikwe amandla ngesoftware. I-pin yangaphandle inikwe kwakhona ukuxhasa ukhuseleko lokubhala. Le pinout kwi-SODIMM pinout yayiyiphini lomhlaba, ngoko ngokungagqibekanga ukuba ukhuseleko lokubhala luvuliwe nge-software i-EEPROM ibhaliwe ikhuselwe. Akukhuthazwa ukuba i-EEPROM ihlaziywe kwintsimi. Nje ukuba uphuhliso lwesistim lugqityiwe i-EEPROM kufuneka ibhalwe-ikhuselwe ngesoftware ukuthintela utshintsho lwangaphakathi.
Kufuneka utshintsho lweSoftware
Ukuba usebenzisa iRaspberry Pi OS ehlaziywe ngokupheleleyo emva koko utshintsho lwesoftware olufunekayo xa uhamba phakathi kwazo naziphi na iibhodi zeRaspberry Pi Ltd zincinci; inkqubo ibhaqa ngokuzenzekelayo ukuba yeyiphi ibhodi esebenzayo kwaye iya kuseka inkqubo yokusebenza ngokufanelekileyo. Ngoko, umzekeloampLe, ungahambisa umfanekiso wakho we-OS ukusuka kwiRaspberry Pi CM 3+ ukuya kwiRaspberry Pi CM 4S kwaye kufuneka isebenze ngaphandle kotshintsho.
PHAWULA
Kuya kufuneka uqinisekise ukuba ufakelo lwakho lweRaspberry Pi OS luhlaziyiwe ngokudlula kwindlela yokuhlaziya eqhelekileyo. Oku kuya kuqinisekisa ukuba yonke isoftware ye-firmware kunye ne-kernel ifanelekile kwisixhobo esisetyenziswayo.
Ukuba uphuhlisa eyakho i-kernel encinci yokwakha okanye unayo nayiphi na i-customizations kwifolda ye-boot ke kunokubakho iindawo apho kuya kufuneka uqiniseke ukuba usebenzisa ukuseta okuchanekileyo, ukuhombisa, kunye nabaqhubi.
Ngelixa usebenzisa iRaspberry Pi OS ehlaziyiweyo kufuneka ithethe ukuba utshintsho lubonakala elubala, kwezinye izicelo 'zentsimbi engenanto' kunokwenzeka ukuba ezinye iidilesi zememori zitshintshile kwaye uphinda-phindo lwesicelo luyafuneka. Bona amaxwebhu e-BCM2711 peripherals ngeenkcukacha ezithe kratya kwiifitsha ezongezelelweyo ze-BCM2711 kunye needilesi zerejista.
Ukuhlaziya i-firmware kwinkqubo endala
Kwezinye iimeko akunakukwazi ukuhlaziya umfanekiso kuhlobo lwamva nje lweRaspberry Pi OS. Nangona kunjalo, ibhodi yeCM4S iya kusafuna i-firmware ehlaziyiweyo ukuze isebenze ngokuchanekileyo. Kukho iphepha elimhlophe elifumanekayo kwiRaspberry Pi Ltd elichaza ukuhlaziya i-firmware ngokweenkcukacha, nangona kunjalo, ngokufutshane, inkqubo imi ngolu hlobo lulandelayo:
Khuphela i-firmware files ukusuka kule ndawo ilandelayo: https://github.com/raspberrypi/firmware/archive/refs/heads/stable.zip
Le zip file iqulathe izinto ezininzi ezahlukeneyo, kodwa abo sinomdla kule stagIi zikwincwadi yokuqalisa.
Ifirmware files banamagama efom qala*.elf kunye nenkxaso ehambelana nayo files ukulungisa*.dat.
Umgaqo osisiseko kukukopa ukuqala kunye nokulungiswa okufunekayo files kule zip file ukubuyisela igama elifanayo files kumfanekiso wendlela yokusebenza yendawo. Inkqubo echanekileyo iya kuxhomekeka kwindlela yokusebenza emiswe ngayo, kodwa njenge exampLe yindlela eya kwenziwa ngayo kumfanekiso weRaspberry Pi OS.
- Khupha okanye uvule i-zip file ukuze ukwazi ukufikelela okufunekayo files.
- Vula isiqulathi seefayili kwindawo ekuyiwa kuyo i-OS umfanekiso (oku kunokuba kwikhadi le-SD okanye ikopi esekwe kwidisk).
- Qinisekisa ukuba yeyiphi isiqalo.elf kunye ne-fixup.dat files zikhona kwindawo ye-OS umfanekiso.
- Khuphela ezo files ukusuka kwindawo yokugcina ye-zip ukuya kumfanekiso wendawo.
Umfanekiso ngoku kufuneka ulungele ukusetyenziswa kwi-CM4S.
Imizobo
Ngokungagqibekanga, iRaspberry Pi CM 1–3+ isebenzisa isitaki semizobo yelifa, ngelixa iRaspberry Pi CM 4S isebenzisa istaki semizobo yeKMS.
Ngelixa kunokwenzeka ukusebenzisa isitaki semizobo yelifa kwiRaspberry Pi CM 4S, oku akuxhasi ukukhawuleza kwe-3D, ngoko ke ukuya kwi-KMS kuyacetyiswa.
HDMI
Ngelixa i-BCM2711 inezibuko ezimbini ze-HDMI, kuphela i-HDMI-0 ekhoyo kwi-Raspberry Pi CM 4S, kwaye oku kunokuqhutywa ukuya kuthi ga kwi-4Kp60. Zonke ezinye iindlela zokubonisa (i-DSI, i-DPI kunye ne-composite) azitshintshi.
