Ukuqalisa kunye noqwalaselo
Ii-FPGA ze-PolarFire SoC zisebenzisa i-high-high circuitry ukuqinisekisa amandla athembekileyo ekunyuseni amandla kunye nokusetwa kwakhona. Kumandla-phezulu kunye nokusetha kwakhona, ulandelelwano lwe-PolarFire SoC FPGA ye-boot-up ilandela ukusetwa kwakhona kwe-Power-on (POR), i-Device boot, ukuqaliswa koYilo, i-Microcontroller Subsystem (MSS) yokuqalisa kwangaphambili, kunye ne-MSS yomsebenzisi. Olu xwebhu luchaza ukuqaliswa kwangaphambili kwe-MSS kunye ne-MSS yokuQalisa uMsebenzisi. Ngolwazi malunga ne-POR, i-Device Boot kunye noYilo lokuqalisa, bona i-UG0890: i-PolarFire SoC FPGA Power-Up kunye nokuSeta kwakhona iSikhokelo soMsebenzisi.
Ngolwazi oluthe vetshe malunga neempawu ze-MSS, bona i-UG0880: Isikhokelo Somsebenzisi se-PolarFire SoC MSS.
Ulandelelwano lokuQalisa
Ulandelelwano lwe-boot-up luqala xa i-PolarFire SoC FPGA inikwe amandla okanye iphinda isetyenziswe. Iphela xa iprosesa ilungele ukwenza inkqubo yesicelo. Olu landelelwano lokuqalela lubaleka kwimizuzu emininzitages phambi kokuba iqale ukuphunyezwa kweenkqubo.
Iseti yemisebenzi yenziwa ngexesha lenkqubo yokuBoot-up equka ukusetwa kwakhona kwamandla kwe-hardware, ukuqaliswa kweperipheral, ukuqaliswa kwememori, kunye nokulayisha isicelo esichazwe ngumsebenzisi ukusuka kwimemori engaguqukiyo ukuya kwimemori eguquguqukayo ukuze iqhutywe.
Lo mfanekiso ulandelayo ubonisa izigaba ezahlukeneyo zolandelelwano lwe-Boot-up.
Umzobo 1 Ulandelelwano lokuQalisa
I-MSS Pre-Boot
Ekugqityweni ngempumelelo koYilo lokuQalisa, i-MSS Pre-boot iqalisa ukwenziwa kwayo. I-MSS iyakhululwa ekusetweni ngokutsha emva kokugqitywa kwazo zonke iinkqubo eziqhelekileyo zokuqalisa. Umlawuli wenkqubo ulawula ukucwangcisa, ukuqaliswa, kunye nokucwangciswa kwezixhobo. Ukuqalisa kwangaphambili kwe-MSS akwenzeki ukuba isixhobo esicwangcisiweyo siqwalaselelwe indlela yokunqumamisa isilawuli senkqubo.
Isigaba sokuqala se-MSS sokuqalisa silungelelaniswa yi-firmware yomlawuli wenkqubo, nangona inokusebenzisa i-E51 kwi-MSS Core Complex ukwenza iindawo ezithile zokulandelelana kwangaphambi kokuqalisa.
Ezi ziganeko zilandelayo zenzeka ngexesha le-MSS pre-boot stage:
- Amandla aphezulu e-MSS ezinziswe iMemori engaguquguqukiyo (eNVM)
- Ukuqaliswa kokulungiswa kokungafuneki okuhambelana ne-MSS Core Complex L2 cache
- Ungqinisiso lwekhowudi yokuqalisa yoMsebenzisi (ukuba uMsebenzisi oKhuselekileyo ukhetho lwesiqalo luvuliwe)
- Ukunikezela ngeMSS esebenzayo kwikhowudi yokuQalisa uMsebenzisi
I-MSS Core Complex inokuqaliswa kwenye yeendlela ezine. Le theyibhile ilandelayo idwelisa iinketho zokuqalisa kwangaphambili ze-MSS, ezinokumiselwa kwaye zicwangciswe kwi-sNVM. Indlela yokuqalisa ichazwa yiparameter yomsebenzisi U_MSS_BOOTMODE[1:0]. Idatha eyongezelelweyo yokumisela i-boot ixhomekeke kwimowudi kwaye ichazwa yiparameter yomsebenzisi U_MSS_BOOTCFG (bona iTheyibhile 3, iphepha 4 kunye neTheyibhile 5, iphepha 6).
Uluhlu 1 • Iindlela zokuQalisa eziNqabileyo ze-MSS
| U_MSS_BOOTMODE[1:0] | Imowudi | Inkcazo |

| 3 | Ukuqalisa okukhuselekileyo kwasefektri | Iibhutsi ze-MSS Core Complex zisebenzisa iprotocol ekhuselekileyo yasefektri |
Ukhetho lwesiqalo lukhethiwe njengenxalenye yoyilo lokuhamba kweLibero. Ukutshintsha indlela kunokufezekiswa kuphela ngokuveliswa kwenkqubo entsha yeFPGA file.
Umzobo 2 • Ukuqukuqela kwe-MSS Pre-boot 
I-Idle Boot
Ukuba i-MSS ayilungiselelwanga (ngokomzekeloample, isixhobo esingenanto), emva koko iMSS Core Complex iphumeze inkqubo yeROM yesiqalo ebamba zonke abaqhubekekisi kwilophu engapheliyo de idebugger iqhagamshela kwitekeni. Iirejista zeVector yesiqalo zigcina ixabiso lazo de isixhobo sisetyenziselwe ngokutsha okanye uqwalaselo olutsha lwemowudi yokuqalisa lucwangcisiwe. Kwizixhobo eziqwalaselweyo, le mowudi inokuphunyezwa ngokusebenzisa i
U_MSS_BOOTMODE=0 ukhetho lokuqalisa kwi-Libero configurator.
Phawula: Kule modi, U_MSS_BOOTCFG ayisetyenziswa.
Lo mfanekiso ulandelayo ubonisa ukuhamba kwe-Idle boot.
Umfanekiso 3 • Ukuhamba KweziBothi Ezingasebenziyo
UkuQalisa okungakhuselekanga
Kule ndlela, iMSS Core Complex iphumeza idilesi ye-eNVM ekhankanyiweyo ngaphandle koqinisekiso. Ibonelela ngeyona ndlela ikhawulezayo yokuqalisa, kodwa akukho siqinisekiso somfanekiso wekhowudi. Idilesi ingachazwa ngokumisela U_MSS_BOOTADDR kwiLibero Configurator. Le ndlela inokuphinda isetyenziswe ukuqalisa kuyo nayiphi na i-FPGA Fabric yesixhobo senkumbulo nge-FIC. Le ndlela iphunyezwa ngokusebenzisa i
U_MSS_BOOTMODE=1 indlela yokuqalisa.
I-MSS Core Complex ikhutshiwe ekusetweni ngokutsha ngeevekhtha zokuqalisa ezichazwe ngu-U_MSS_BOOTCFG (njengoko kudweliswe kuluhlu olulandelayo).

UkuQalisa uMsebenzisi oKhuselekileyo
Le ndlela ivumela umsebenzisi ukuba aphumeze eyabo inkqubo ekhuselekileyo yokuqalisa kunye nekhowudi yokuqalisa ekhuselekileyo yomsebenzisi ibekwe kwi-sNVM. I-sNVM yi-56 KB yememori engaguqukiyo enokuthi ikhuselwe nguMsebenzi oNgamelekiyo owakhelwe ngaphakathi (PUF). Le ndlela yokuqalisa ithathwa njengekhuselweyo kuba amaphepha e-sNVM aphawulwe njenge-ROM awatshintsheki. Ekunyuseni amandla, umlawuli wenkqubo ukopisha ikhowudi yokuqalisa ekhuselekileyo yomsebenzisi ukusuka kwi-sNVM ukuya kwiMemori eQinisekisiweyo eDityanisiweyo yeDatha (DTIM) ye-E51 Monitor core. E51 iqala ukwenza umsebenzisi ikhowudi yokuqalisa ekhuselekileyo.
Ukuba ubungakanani bomsebenzisi ikhowudi yesiqalo ekhuselekileyo ingaphezulu kobungakanani be DTIM ngoko umsebenzisi ufuna ukwahlula ikhowudi yesiqalo ibe ngamacandelo amabini.tages. I-sNVM inokuqulatha okulandelayotage yolandelelwano lwesiqalo somsebenzisi, olunokwenza uqinisekiso lwesiqalo esilandelayo stage usebenzisa uqinisekiso lomsebenzisi/uguqulelo lwealgorithm.
Ukuba amaphepha aqinisekisiweyo okanye afihliweyo asetyenziswa ngoko kwalelo qhosha le-USK (oko kukuthi,
U_MSS_BOOT_SNVM_USK) kufuneka isetyenziswe kuwo onke amaphepha aqinisekisiweyo/afihliweyo.
Ukuba uqinisekiso aluphumeleli, iMSS Core Complex inokubekwa ngokutsha kwaye iBOOT_FAIL tampiflegi inokuphakanyiswa. Le ndlela iphunyeziwe ngokusebenzisa i U_MSS_BOOTMODE=2 ukhetho lokuqalisa.

Umfanekiso 5 • UkuHamba ngokuKhuseleka kweMsebenzi yokuQalisa
UKhuseleko lwe-Factory Boot
Kule ndlela, umlawuli wenkqubo ufunda iSiqinisekiso soMfanekiso oKhuselekileyo wokuQalisa (i-SBIC) kwi-eNVM kwaye aqinisekise i-SBIC. Ekuqinisekiseni okuyimpumelelo, uMlawuli weSixokelelwano ukhuphela ikhowudi yokuqalisa ekhuselekileyo yasefektri kwindawo yayo yabucala, ekhuselekileyo yememori kwaye iyilayishe kwi-DTIM ye-E51 Monitor core. Ukuqala okukhuselekileyo okumiselweyo kwenza utyikityo lokutshekisha kumfanekiso we-eNVM usebenzisa i-SBIC egcinwe kwi-eNVM. Ukuba akukho ziphoso zixeliweyo, ukuseta ngokutsha kukhutshwa kwi-MSS Core Complex. Ukuba iimpazamo zixeliwe, iMSS Core Complex ibekwe ngokutsha kunye ne BOOT_FAIL tampiflegi iphakanyisiwe. Emva koko, umlawuli wenkqubo usebenza kwiamper iflegi ebanga uphawu kwilaphu yeFPGA yesenzo somsebenzisi. Le ndlela iphunyeziwe ngokusebenzisa i U_MSS_BOOTMODE=3 ukuqalisa ukhetho.
I-SBIC iqulethe idilesi, ubungakanani, ihashi, kunye ne-Elliptic Curve Digital Signature Algorithm (ECDSA) umsayino weblob yokubini ekhuselweyo. I-ECDSA ibonelela ngokwahlukileyo kwi-Digital Signature Algorithm esebenzisa i-elliptic curve cryptography. Ikwanayo nevector yokusetha kwakhona kwi-Hardware nganye
umsonto/undoqo/undoqo weprosesa (Hart) kwinkqubo.

Ukuba indawo ye-DSN ayingo-zero, ithelekiswa nenombolo yesiriyali yesixhobo. Ukuba uthelekiso aluphumeleli, ngoko i-boot_fail tampiflegi isetiwe kwaye uqinisekiso luyalahlwa.
IVERSION
Ukuba urhoxiso lwe-SBIC lwenziwe ngu-U_MSS_REVOCATION_ENABLE, i-SBIC iyakhatywa ngaphandle kokuba ixabiso le-VERSION likhulu okanye lilingana nomda wokurhoxiswa.
I-SBIC REVOCATION OPTION
Ukuba urhoxiso lwe-SBIC lwenziwe ngu-U_MSS_REVOCATION_ENABLE kunye ne-OPTIONS[0] ngu-'1', zonke iinguqulelo ze-SBIC ezingaphantsi kwe-VERSION ziyarhoxiswa xa uqinisekiso olupheleleyo lwe-SBIC. Umda wokurhoxiswa uhlala kwixabiso elitsha de unyuke kwakhona nge-SBIC yexesha elizayo nge-OPTIONS[0] = '1' kunye nomhlaba ophezulu we-VERSION. Umda worhoxiso unokunyuswa kuphela kusetyenziswa lo matshini kwaye unokusetwa kwakhona ngosinga-msinga.
Xa umda worhoxiso uhlaziywa ngamandla, umda ugcinwa kusetyenziswa iskimu sogcino olungafunekiyo olusetyenziswa kwiikhowudi zokugqitha ukuze ukusilela kombane ngexesha lokuqalisa isixhobo akubangeli ukuqalisa kwesixhobo esilandelayo ukuba sisilele. Ukuba uhlaziyo lomqobo wokurhoxiswa aluphumeleli, kuyaqinisekiswa ukuba ixabiso lomqobo lixabiso elitsha okanye elingaphambili.
