Lo mzobo ungezantsi ubonisa umjikelo wobomi bemveliso yezixhobo ze-STM32MP15x.

Izithintelo zebhodi karhulumente ye-RMA

Ukwenza i-RMA isebenze, le miqobo ilandelayo iyafuneka.
Inkqubo kaJTAG ukufikelela kufuneka kufumaneke
Iimpawu ze-NJTRST kunye ne-JTDI, i-JTCK, i-JTMS, i-JTDO (i-pin PH4, PH5, PF14, PF15 kwizixhobo ze-STM32MP13xx) kufuneka zifikeleleke. Kwezinye izixhobo, i-JTDO ayiyomfuneko (ngokomzekeloample, Trace32) kwenye njenge OpenOCD isixhobo sijonga isixhobo uJTAG I-ID nge-JTDO ngaphambi kokwenza i-JTAG ulandelelwano.

I-VDDCORE kunye ne-VDD unikezelo lwamandla akufuneki lucinywe xa i-pin ye-NRST ivuliwe
Kuyilo lwereferensi ye-ST, i-NRST ivula umjikelo wamandla we-STPMIC1x okanye izilawuli zamandla zamacandelo angaphandle. Ukuphunyezwa okunokwenzeka kubonisiwe kuyilo lwereferensi example inikezelwe kwinqaku lesicelo Ukuqalisa nge-STM32MP13x imigca yophuhliso lwehardware (AN5474) . Umzobo 3 kunye noMzobo 4 ziinguqulelo ezenziwe lula ezibonisa kuphela amacandelo anxulumene norhulumente we-RMA. Kukwasebenza okufanayo nakwizixhobo ze-STM32MP15xx.

Ibhodi elula ene-J kuphelaTAG iphini kunye nesokethi efanelekileyo inokusetyenziselwa iinjongo zegama lokugqitha le-RMA kuphela (ukuba akunakwenzeka ukufikelela kwi-JTAG kwibhodi yemveliso). Kwimeko enjalo umthengi kufuneka aqale akhuphe isixhobo kwibhodi yemveliso kwaye aphinde azalise iibhola zephakheji.

Iimfuno zangaphambili zokuvumela urhulumente we-RMA wexesha elizayo ukuba angene

Ithuba lokungena kwimeko ye-RMA kufuneka imiselwe ngumthengi ngokufaka igama eliyimfihlo ngexesha lokuvelisa umthengi emva kokunikezelwa ngokufihlakeleyo

• Isixhobo xa sithunyelwe sisuka kwi-STMicroelectronics sikwimo evulekileyo ye-OTP_SECURED.
• Isixhobo siqulethe iimfihlo ze-ST ezikhuselwe yi-boot ROM, kwaye akukho mfihlo yomthengi.
• Ekusetweni ngokutsha okanye emva kokuqaliswa kwe-ROM yokuqalisa, ufikelelo lwe-DAP lunokuphinda luvulwe yi-Linux okanye nge-boot ye-ROM “imowudi yophuhliso” (OTP_SECURED vula + izikhonkwane ze-boot BOOT[2:0]=1b100 + ukuseta kwakhona).
• Ngelixa i-OTP_SECURED ivuliwe, umthengi kufuneka abonelele ngeemfihlo zakhe kwi-OTP:
  • ngokuthe ngqo ngumthengi ngomngcipheko okanye
  • ngokukhuselekileyo ngesitishi esifihliweyo usebenzisa "inqaku le-SSP" ye-ROM yokuqalisa kunye nezixhobo ze-STM32.
• Ekupheleni kokunikezelwa kweemfihlo, umthengi unokudibanisa:
  • Kwi-STM32MP13xx i-32 bit RMA password kwi OTP_CFG56 (igama lokugqitha kufuneka libe ngu-0).
  • Kwi-STM32MP15xx i-15 bit RMA password kwi-OTP_CFG56[14:0], i-RMA_RELOCK yokugqitha kwi-OTP_CFG56[29:15].
    Igama lokugqithisa kufuneka lahluke kuno-0.
• Cwangcisa i-OTP_CFG56 njenge "isitshixo senkqubo esisisigxina" ukunqanda inkqubo kamva kwi-0xFFFFFF kwaye uvumele ukungena kwimo ye-RMA ngaphandle kolwazi lwegama lokugqitha lokuqala.
• Qinisekisa inkqubo echanekileyo ye OTP_CFG56 ngokujonga i-BSEC_OTP_STATUS irejista.
• Okokugqibela, isixhobo sitshintshelwa kwi-OTP_SECURED sivaliwe:
  • Kwi-STM32MP13xx ngokudibanisa i-OTP_CFG0[3] = 1 kunye ne-OTP_CFG0[5] = 1.
  • Kwi-STM32MP15xx ngokudibanisa i-OTP_CFG0[6] = 1.
    Isixhobo sinokuphinda sivulwe kwimeko ye-RMA ukuze kuphandwe yi-STMicroelectronics
• Xa isixhobo sikwisimo esivaliweyo se-OTP_SECURED, "uphuhliso lwesiqalo" alusenakwenzeka.

I-RMA ichaza iinkcukacha

Njengoko bekutshiwo ngaphambili, urhulumente we-RMA usetyenziselwa ukuphinda uvule ngokukhuselekileyo imo yovavanyo epheleleyo ngaphandle kokuvezwa kweemfihlo ezilungiselelwe umthengi. Oku kwenziwa ngenxa yokusebenza kukaJTAG amagalelo ngelixa zonke iimfihlo zabathengi zigcinwa zingafikeleleki nge-hardware.

Kwimeko apho kukho imfuneko yohlalutyo kwi-s engaphumeleliyoample kukho isidingo sokuya kwi-RMA state (jonga umfanekiso 5. Ukutshintshela kwi-OTP_SECURED ivaliwe), ekhusela iimfihlo zabathengi kwaye iphinde ivule i-debug ekhuselekileyo kwaye ingakhuselekanga kwi-DAP.

1. Umthengi uyatshintsha kwi-BSEC_JTAGEKUBHALISENI igama lokugqithisa le-RMA usebenzisa i-JTAG (kuphela amaxabiso ahlukileyo ku-0 amkelweyo).
2. Umthengi useta kwakhona isixhobo (i-pin ye-NRST).
   Phawula: Ngeli nyathelo, igama lokugqithisa kwi-BSEC_JTAGKWIrejista mayingacinywa. Ngoko ke, i-NRST akufuneki ivale i-VDD okanye i-VDDCORE unikezelo lwamandla. Akufunekanga kwakhona idityaniswe kwiphini ye-NJTRST. Kwimeko apho STPMIC1x isetyenzisiwe, kunokuba yimfuneko ukugquma unikezelo lwamandla ngexesha lokuseta ngokutsha. Oku kwenziwa ngokucwangcisa i STPMIC1x irejista yokukhetha imaski (BUCKS_MRST_CR) okanye ukususa isichasi esongezelelwe i-RMA ebhodini phakathi kwe-STPMICx RSTn kunye ne-STM32MP1xxx NRST (jonga uMfanekiso 3).
3. I-ROM yokuqalisa iyabhengezwa kwaye ijonga igama lokugqitha le-RMA elifakwe kwi-BSEC_JTAGIN nge OTP_CFG56.RMA_PASSWORD:
   • Ukuba iipassword ziyahambelana, i-sample iba yi RMA_LOCK sample (ngonaphakade kwi-STM32MP13xx).
   • Ukuba iipassword azingqinelani, ikampi-le ihlala kwi-OTP_SECURED imo evaliweyo kwaye i-RMA "yokuvula kwakhona iimvavanyo" counter yongezwa kwi-OTP.
   Phawula: Kuphela ngamalingo amathathu okuvulwa kwakhona kwe-RMA agunyazisiweyo. Emva kwezilingo ezintathu ezingaphumelelanga, ukuvulwa kwakhona kwe-RMA akusenakwenzeka. Isixhobo sihlala kwisimo saso somjikelo wobomi.
4. Umthengi useta kwakhona okwesibini i-sample nge-NRST pin:
   • I-LED kwi-PA13 ivuliwe (ukuba iqhagamshelwe)
   • Ufikelelo lolungiso lwe-DAP luvulwe kwakhona.
5. Isixhobo sinokuthunyelwa kwi-STMicroelectronics.
6. Emva kokusetha ngokutsha (i-NRST pin okanye nayiphi na inkqubo yokuseta ngokutsha), i-ROM yokuqalisa iyabhengezwa:
   • Ibhaqa ukuba i-OTP8.RMA_LOCK = 1 (i-RMA itshixiwe sample).
   • Ikhusela zonke ii-STMicroelectronics neemfihlo zabathengi.
   • Iphinda ivule ufikelelo lolungiso lwe-DAP kwindawo ekhuselekileyo nengakhuselekanga.

Ngelixa ikwisimo se-RMA inxalenye ayihoyi izikhonkwane zeBoot kwaye ayikwazi ukuqalisa kwi-flash yangaphandle okanye i-USB/UART.

Iinkcukacha zokuvula i-RMA

Kwi-STM32MP15xx kuyenzeka ukuba uvule isixhobo ukusuka kwi-RMA kwaye ubuyele kwi-SECURE_CLOSED imo.
Kwi-BSEC_JTAGKWIrejista, umthengi utshintsha igama lokuvula le-RMA esebenzisa i-JTAG (kuphela amaxabiso ahlukileyo ku-0 amkelweyo)

• Umthengi useta kwakhona isixhobo (i-pin ye-NRST).
  Phawula: Zintathu kuphela izilingo zokuvula i-RMA ezigunyazisiweyo. Emva kwezilingo ezintathu ezingaphumelelanga, ukuvula i-RMA akusenakwenzeka. Isixhobo sihlala kwisimo somjikelo wobomi be-RMA.
• Umthengi useta kwakhona okwesibini i-sample nge-NRST pin:
  • I-LED kwi-PA13 ivuliwe (ukuba iqhagamshelwe),
  • isixhobo sikwimeko ye-SECURE_CLOSED (ufikelelo lolungiso lwe-DAP luvaliwe).
