Whakarewa me te Whirihoranga
Ko nga PolarFire SoC FPGA e whakamahi ana i nga hiko hiko-ake teitei hei whakapumau i te mana pono i te hiko-ake me te tautuhi. I te whakakaha me te tautuhi, ka whai te raupapa whakaohooho a PolarFire SoC FPGA i te Whakahou Mana (POR), te Whakaoho i te taputapu, te Awhitinga Hoahoa, te Microcontroller Subsystem (MSS) i mua i te boot, me te whawhai kaiwhakamahi MSS. Ko tenei tuhinga e whakaatu ana i te MSS mua-boot me te MSS Kaiwhakamahi Boot. Mo nga korero e pa ana ki te POR, te Whakaara Pūrere me te Whakaaratanga Hoahoa, tirohia UG0890: PolarFire SoC FPGA Power-Up me te Tautuhi Arahi Kaiwhakamahi.
Mo etahi atu korero mo nga ahuatanga MSS, tirohia UG0880: PolarFire SoC MSS Aratohu Kaiwhakamahi.
Raupapa Whakaoho
Ka timata te raupapa whakaoho i te wa e whakakahangia ana te PolarFire SoC FPGA, kua tautuhia ranei. Ka mutu i te wa e reri ana te tukatuka ki te whakahaere i tetahi kaupapa tono. He maha nga wa e rere ana tenei raupapa whakaohotagi mua i te tiimata o te whakatinanatanga o nga kaupapa.
Ka mahia he huinga mahi i roto i te tukanga Whakaara ka uru ki te whakahou i te mana o te taputapu, te arawhitinga peripheral, te whakamaarama mahara, me te utaina o te tono kua tautuhia e te kaiwhakamahi mai i te mahara kore-kore ki te mahara ohorere mo te mahi.
Ko te ahua e whai ake nei e whakaatu ana i nga waahanga rereke o te raupapa Whakaara.

MSS Tuhinga o mua
I te otinga angitu o te Whakatairanga Hoahoa, ka timata a MSS Pre-boot i tana mahi. Ka tukuna te MSS mai i te tautuhi i muri i te otinga o nga tikanga whakaoho noa. Ko te kaiwhakahaere o te punaha te whakahaere i te hotaka, te arataki, me te whirihoranga o nga taputapu. Ko te MSS Pre-boot e kore e puta ki te whirihorahia te taputapu kua whakahōtakahia mo te aratau whakatārewa a te kaiwhakahaere punaha.
Ko te wahanga MSS i mua i te whakaohoohotanga ka rurukuhia e te punaha mana whakahaere, ahakoa ka whakamahia pea e ia te E51 i roto i te MSS Core Complex hei mahi i etahi waahanga o te raupapa o mua-boot.
Ko nga kaupapa e whai ake nei ka puta i te wa o te MSS mua-boot stage:
- Whakanuia o te Mahara Kore-Volatile (eNVM) kua mau ki te MSS
- Ko te timatanga o te whakatikanga taapiri e hono ana ki te keteroki MSS Core Complex L2
- Motuhēhēnga o te Waehere Whakaoho Kaiwhakamahi (mehemea ka whakahohea te whiringa whawhai Haumaru Kaiwhakamahi)
- Te tuku MSS whakahaere ki te Waehere Whakaara Kaiwhakamahi
Ko te MSS Core Complex ka taea te peke i tetahi o nga momo e wha. Ko te ripanga e whai ake nei e whakaatu ana i nga whiringa MSS i mua i te whawhai, ka taea te whirihora me te whakamahere ki te sNVM. Ko te aratau whawhai e tautuhia ana e te tawhā kaiwhakamahi U_MSS_BOOTMODE[1:0]. Ko etahi atu raraunga whirihoranga whawhai e whakawhirinaki ana ki te aratau, kua tautuhia e te tawhā kaiwhakamahi U_MSS_BOOTCFG (tirohia te Ripanga 3, wharangi 4 me te Ripanga 5, wharangi 6).
Ripanga 1 • MSS Core Matatini Whakaara Aratau

Whakaoho Whakakore
Mena kaore i te whirihorahia te MSS (mo te exampte, he taputapu tuwhera), katahi ka mahia e te MSS Core Complex he kaupapa boot ROM e pupuri ana i nga kaitukatuka katoa i roto i te kohanga mutunga kore tae noa ki te hono atu o te patuiro ki te whaainga. Ka mau tonu te wariu o nga rehita vector boot tae noa ki te tautuhi i te taputapu, ki te whakarite ranei i tetahi whirihoranga aratau whawhai hou. Mo nga taputapu whirihora, ka taea te whakamahi i tenei aratau ma te whakamahi i te
U_MSS_BOOTMODE=0 kōwhiringa whawhai i roto i te whirihora Libero.
Tuhipoka: I tenei aratau, kaore i te whakamahia a U_MSS_BOOTCFG.
Ko te ahua e whai ake nei e whakaatu ana i te rere whawhai Idle.

Boot-kore
I tenei aratau, ka mahia e te MSS Core Complex mai i tetahi wahitau eNVM kua tohua me te kore motuhēhēnga. E whakarato ana i te kōwhiringa whawhai tere, engari kaore he motuhēhēnga o te whakapakoko waehere. Ka taea te tautuhi i te wahitau ma te whakatakoto U_MSS_BOOTADDR ki te Libero Configurator. Ka taea hoki te whakamahi i tenei aratau ki te peke mai i tetahi rauemi mahara FPGA Fabric ma te FIC. Ka whakatinanahia tenei aratau ma te whakamahi i te
U_MSS_BOOTMODE=1 kōwhiringa whawhai.
Ko te MSS Core Complex ka tukuna mai i te tautuhi me nga vectors boot i tautuhia e U_MSS_BOOTCFG (penei i te raarangi e whai ake nei).

Whakaara Haumaru Kaiwhakamahi
Ma tenei aratau ka taea e te kaiwhakamahi te whakatinana i o raatau ake momo peke haumaru ka tuuhia te waehere boot haumaru kaiwhakamahi ki te sNVM. Ko te sNVM he 56 KB te mahara kore-kore e taea te parea e te Whakamahinga Kore-a-tinana (PUF) i hangaia. Ko tenei tikanga whawhai e kiia ana he haumaru na te mea ko nga wharangi sNVM kua tohua hei ROM e kore e huri. I runga i te hiko, ka kapehia e te kaiwhakahaere o te punaha te waehere boot haumaru a te kaiwhakamahi mai i te sNVM ki te Raraunga Maahara Whakauru (DTIM) o te E51 Monitor matua. Ka timata a E51 ki te whakamahi i te waehere boot haumaru kaiwhakamahi.
Mena he nui ake te rahi o te waehere boot haumaru kaiwhakamahi i te rahi o te DTIM katahi ka hiahia te kaiwhakamahi ki te wehe i te waehere boot ki te rua stages. Kei roto pea i te sNVM nga s e whai ake neitage o te raupapa whakaoho o te kaiwhakamahi, ka taea te whakamana i nga s o muri maitage whakamahi ana i te motuhēhēnga/whakamunatanga hātepe.
Mēnā ka whakamahia ngā whārangi whakamotuhēhē, whakamunatia rānei, ko taua kī USK (ara,
U_MSS_BOOT_SNVM_USK) me whakamahi mo nga wharangi whakamotuhēhē/whakamuna.
Mena ka rahua te whakamotuhēhēnga, ka taea te whakauru i te MSS Core Complex ki te tautuhi me te BOOT_FAIL tampka taea te hiki te haki. Ka whakatinanahia tenei aratau ma te whakamahi i te U_MSS_BOOTMODE=2 kōwhiringa whawhai.

Wheketere Whakaara Haumaru
I tenei aratau, ka panuihia e te kaiwhakahaere o te punaha te Tiwhikete Tiwhikete Whakaahua Whakaara Haumaru (SBIC) mai i te eNVM me te whakamana i te SBIC. I runga i te whakamanatanga angitu, ka kapehia e te Kaiwhakahaere Pūnaha te waehere whawhai haumaru wheketere mai i tana waahi whakamaumahara haumaru, ka utaina ki te DTIM o te E51 Monitor matua. Ka mahia e te putu haumaru taunoa he haki hainatanga ki te ahua eNVM ma te whakamahi i te SBIC kei te rongoa i roto i te eNVM. Mena karekau he hapa, ka tukuna te tautuhi ki te MSS Core Complex. Mena ka puta nga hapa, ka whakauruhia te MSS Core Complex ki te tautuhi me te BOOT_FAIL tampka whakaarahia te haki. Na, ka whakahohe te kaiwhakahaere punaha iamper haki e kii ana he tohu ki te papanga FPGA mo te mahi a te kaiwhakamahi. Ka whakatinanahia tenei aratau ma te whakamahi i te U_MSS_BOOTMODE=3 kōwhiringa whawhai.
Kei roto i te SBIC te waahi noho, te rahi, te hash, me te Elliptic Curve Digital Signature Algorithm (ECDSA) waitohu o te putunga rua kua parea. E tuku ana a ECDSA i tetahi momo rerekee o te Algorithm Waitohu Mamati e whakamahi ana i te whakamunatanga o te kurupae elliptic. Kei roto hoki te vector tautuhi mo ia Pūmārō
miro/matua/tukatuka matua (Hart) i roto i te punaha.

DSN
Mena he kore-kore te mara DSN, ka whakatauritea ki te tau rangatū o te taputapu. Mena ka rahua te whakataurite, na te boot_fail tampkua tautuhia te haki ka whakatakahia te motuhēhēnga.
PUTANGA
Mena ka whakahohea te whakakorenga SBIC e U_MSS_REVOCATION_ENABLE, ka paopaohia te SBIC ki te kore te uara o VERSION he nui ake, he rite ranei ki te paepae whakakore.
SBIC KOWHITI WHAKATANGA
Mena ka whakahohea te whakakorenga SBIC e U_MSS_REVOCATION_ENABLE a ko OPTIONS[0] ko '1', ko nga putanga SBIC katoa iti iho i te VERSION ka whakakorehia ina oti te motuhēhēnga o te SBIC. Ka noho tonu te paepae whakakorenga ki te uara hou kia piki ake ano e te SBIC a meake nei me nga OPTIONS[0] = '1' me tetahi mara PUTANGA teitei ake. Ka taea anake te whakanui ake i te paepae whakakorenga ma te whakamahi i tenei tikanga, ka taea anake te tautuhi ma te awa-bit.
Ina whakahōuhia te paepae whakakorenga, ka penapenahia te paepae ma te whakamahi i te kaupapa rokiroki taapiri e whakamahia ana mo nga kupuhipa penei i te korenga o te hiko i te wa e whakaohohia ana te taputapu e kore ai e taka te whawhai o muri mai. Ki te rahua te whakahōutanga o te paepae whakakorenga, ka taurangitia ko te uara paepae ko te uara hou, ko te uara o mua ranei.
