Uhlaziyo lwe-ESPRESSIF ESP32 Chip v3.0

Utshintsho loyilo kuHlaziyo lweChip v3.0

I-Espressif ikhuphe utshintsho lwe-wafer-level kwi-ESP32 Series yeemveliso (ukuhlaziywa kwe-chip v3.0). Olu xwebhu luchaza umahluko phakathi kohlaziyo lwe-chip v3.0 kunye nohlaziyo lwangaphambili lwe-ESP32 lwetshiphu. Apha ngezantsi lutshintsho oluphambili loyilo kuhlaziyo lwe-chip v3.0:

1. I-PSRAM Cache Bug Fix: Ilungisiwe "Xa i-CPU ifikelela kwi-SRAM yangaphandle ngokulandelelana okuthile, funda kwaye ubhale iimpazamo." Iinkcukacha zomba zinokufumaneka kwinqaku 3.9 kwi-ESP32 Series SoC Errata.
2. Fixed "Xa i-CPU nganye ifunda izithuba zeedilesi ezahlukeneyo ngaxeshanye, impazamo yokufunda inokwenzeka." Iinkcukacha zomba zinokufumaneka kwinqaku 3.10 kwi-ESP32 Series SoC Errata.
3. Ukulungelelaniswa kwe-32.768 KHz crystal oscillator ukuzinza, umcimbi uxelwe ngumxhasi ukuba kukho ithuba eliphantsi lokuba phantsi kwe-chip v1.0 yokuhlaziywa kwe-hardware, i-32.768 KHz crystal oscillator ayikwazanga ukuqala ngokufanelekileyo.
4. Imiba elungisiweyo yesitofu seFault malunga ne-boot ekhuselekileyo kunye nofihlo lwe-flash iyalungiswa. Ireferensi: Ingcebiso yoKhuseleko malunga nesitofu sempazamo kunye nokhuseleko lwe-eFuse
   (CVE-2019-17391) kunye neNgcebiso yoKhuseleko lwe-Espressif malunga neFault Injection kunye ne-Boot ekhuselekileyo (CVE-2019-15894)
5. Ukuphuculwa: Kutshintshwe ubuncinci bezinga le-baud elixhaswa yimodyuli ye-TWAI ukusuka kwi-25 kHz ukuya kwi-12.5 kHz.
6. Ivunyiwe Ukukhuphela Imowudi yokuQalisa ukuba ingasebenzi umphelo ngenkqubo entsha ye-eFuse bit UART_DOWNLOAD_DIS. Xa le bit icwangciswe ku-1, Khuphela Imowudi yokuQalisa ayinakusetyenziswa kwaye ukuqalela kuya kusilela ukuba izikhonkwane zokurhintshela zimiselwe le mo. Inkqubo yeSoftware le bit ngokubhalela bit 27 ye EFUSE_BLK0_WDATA0_REG, kwaye ufunde le bit ngokufunda bit 27 ye EFUSE_BLK0_RDATA0_REG. Bhala okukhubazekileyo kule bit kwabelwana ngayo nokubhala okukhubaziweyo kwi-flash_crypt_cnt eFuse field.

Impembelelo kwiiProjekthi zabaThengi

Eli candelo lenzelwe ukunceda abathengi bethu baqonde ifuthe lokusebenzisa uhlaziyo lwe-chip v3.0 kuyilo olutsha okanye ukutshintsha inguqulelo endala ye-SoC ngohlaziyo lwe-chip v3.0 kuyilo olukhoyo.

Sebenzisa i-Case 1: i-Hardware kunye noPhuculo lweSoftware
Le yimeko yokusetyenziswa apho iprojekthi entsha iqalwa okanye uphuculo lwehardware kunye nesoftware kwiprojekthi ekhoyo lukhetho olunokwenzeka. Kwimeko enjalo, iprojekthi inokuzuza kukhuseleko kuhlaselo lwenaliti yempazamo kwaye inokuthatha i-advantageyolutsha olukhuselekileyo lwendlela yokuqalisa kunye nolungiso lwebug ye-PSRAM ephuculwe kancinci ukusebenza kwePSRAM.

1. Utshintsho loyilo lweHardware:
   Nceda ulandele iSikhokelo se-Espressif Hardware Design yamva nje. Kwi-32.768 KHz crystal oscillator uzinzo lomba wokuphucula, nceda ubhekisele kwiCandelo leCrystal Oscillator ngolwazi olungakumbi.
2. Utshintsho loYilo lweSoftware:
   1) Khetha Ubuncinane bolungelelwaniso kwi-Rev3: Yiya kwi-menuconfig > Conponent config > ESP32-spespe, kwaye usete i-ESP32 Revision exhaswayo ubuncinane ukhetho ku-“Rev 3”.
   2) Uguqulelo lweSoftware: Ncoma ukuba usebenzise i-boot ekhuselekileyo esekwe kwi-RSA esuka kwi-ESP-IDF v4.1 nasemva koko. Ushicilelo lwe-ESP-IDF v3.X lungasebenza kunye nesicelo kunye nesiqalo esikhuselekileyo se-V1.

Sebenzisa i-Case 2: Uphuculo lwe-Hardware kuphela
Le yimeko yokusetyenziswa apho abathengi baneprojekthi ekhoyo enokuvumela ukuphuculwa kwehardware kodwa isoftware kufuneka ihlale ifana kulo lonke uhlaziyo lwehardware. Kule meko iprojekthi ifumana inzuzo yokhuseleko kuhlaselo lwesitofu sempazamo, i-PSRAM cache bug fix kunye ne-32.768KHz crystal oscillator umba uzinzo. Ukusebenza kwePSRAM kuyaqhubeka kuhlala kunjalo nangona kunjalo.

1. Utshintsho loyilo lweHardware:
   Nceda ulandele isikhokelo samva nje se-Espressif Hardware Design.
2. Utshintsho loYilo lweSoftware:
   Umxhasi unokuqhubeka nokusebenzisa isoftware efanayo kunye nokubini kwiimveliso ezibekiweyo. Ibhinari efanayo yesicelo iya kusebenza kuzo zombini uhlengahlengiso lwe-chip v1.0 kunye nokuhlaziywa kwe-chip v3.0.
