Uyilo loTshintsho kwiChip

I-Espressif ikhuphe uhlaziyo lwetshiphu ye-ESP32 ye-v3.0 ebonisa utshintsho lwenqanaba le-wafer olusekwe kuhlaziyo lwetshiphu ye-ESP32 yangaphambili. Utshintsho loyilo olwaziswa kuhlaziyo lwetshiphu ye-ESP32 v3.0 zezi:

1. Fixed "Ngenxa yexesha lokuqalisa kwe-flash, ukusetwa kwakhona kwe-watchdog eyinkohliso kwenzeka xa i-ESP32 ixhotyiswe okanye ivuka kwi-Deep-sleep". Iinkcukacha zomba zinokufumaneka kwinqaku 3.8 kwi-ESP32 Series SoC Errata.
2. I-PSRAM Cache Bug Fix: Fixed "Xa i-CPU ifikelela kwi-SRAM yangaphandle ngokulandelelana okuthile, funda kwaye ubhale iimpazamo". Iinkcukacha zomba zinokufumaneka kwinqaku 3.9 kwi-ESP32 Series SoC Errata.
3. Fixed "Xa i-CPU nganye ifunda izithuba zeedilesi ezahlukeneyo ngaxeshanye, impazamo yokufunda inokwenzeka". Iinkcukacha zomba zinokufumaneka kwinqaku 3.10 kwi-ESP32 Series SoC Errata.
4. Elungiselelwe 32.768 KHz crystal oscillator uzinzo. Umba uxelwe ngumthengi ukuba kukho amathuba aphantsi ukuba kwi-chip revision v1.0 hardware, i-32.768 KHz crystal oscillator ayikwazanga ukuqalisa ngokufanelekileyo.
5. Imiba elungisiweyo yesitofu seFault malunga ne-boot ekhuselekileyo kunye ne-flash encryption zilungisiwe. Ireferensi: Ingcebiso yoKhuseleko malunga nesitofu esinempazamo kunye nokhuseleko lwe-eFuse (CVE-2019-17391) kunye neNgcebiso yoKhuseleko lwe-Espressif malunga neFault Injection kunye ne-Boot eKhuselekileyo (CVE-2019-15894)
6. Ukuphuculwa: Kutshintshwe ubuncinci bezinga le-baud elixhaswa yimodyuli ye-TWAI ukusuka kwi-25 kHz ukuya kwi-12.5 kHz.
7. 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. Iinkqubo zeSoftware le bit ngokubhalela bit 27 ye EFUSE_BLK0_WDATA0_REG, kwaye ifunde le bit ngokufunda bit 27 ye EFUSE_BLK0_RDATA0_REG. Bhala ukhubazeko kule bit kwabelwana ngayo ngokubhala khubaza kwi-flash_crypt_cnt eFuse indawo.

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 ekukhuselweni ngokuchasene nohlaselo lwenaliti yempazamo kwaye inokuthatha i-advantage yendlela entsha ekhuselekileyo yokuqalisa kunye nolungiso lwe-bug ye-PSRAM ephuculwe kancinci ukusebenza kwe-PSRAM.

1. Utshintsho loyilo lweHardware:
   Nceda ulandele i-ESP32 Hardware Design Guidelines 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 iMinimum Supported ESP32 Revision khetho ku-“Rev 3”.
   2. Uguqulelo lweSoftwe: Cebisa ukuba usebenzise ukuqala ngokukhuselekileyo okusekwe kwiRSA ukusuka 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 lwenaliti yempazamo, ukulungiswa kwe-bug ye-PSRAM ye-cache kunye ne-32.768KHz crystal oscillator umba uzinzo. Ukusebenza kwePSRAM kuyaqhubeka kuhlala kunjalo nangona kunjalo.

1. Utshintsho loyilo lweHardware:
   Nceda ulandele i-ESP32 Hardware Design Guidelines zakutsha nje.
2. Utshintsho loYilo lweSoftware:
   Umxhasi unokuqhubeka nokusebenzisa isoftware efanayo kunye nokubini kwimveliso ebekiweyo. Ibhinari efanayo yesicelo iya kusebenza kuzo zombini uhlengahlengiso lwe-chip v1.0 kunye nokuhlaziywa kwe-chip v3.0.
