Izinguquko Zokuklama ku-Chip

I-Espressif ikhiphe i-ESP32 chip revision v3.0 efaka izinguquko ze-wafer-level ngokusekelwe kuzibuyekezo ze-chip ze-ESP32 zangaphambilini. Izinguquko zokuklama ezethulwe ku-ESP32 chip revision v3.0 yilezi:

1. Kulungisiwe “Ngenxa yesikhathi sokuqalisa kwe-flash, ukusetha kabusha okuyinkohliso kwe-watchdog kwenzeka lapho i-ESP32 inikwa amandla noma ivuka ku-Deep-sleep”. Imininingwane yodaba ingatholakala entweni 3.8 ku-ESP32 Series SoC Errata.
2. I-PSRAM Cache Bug Fix: Ilungisiwe “Lapho i-CPU ifinyelela i-SRAM yangaphandle ngokulandelana okuthile, amaphutha okufunda nokubhala angenzeka”. Imininingwane yodaba ingatholakala entweni 3.9 ku-ESP32 Series SoC Errata.
3. Kulungisiwe “Lapho i-CPU ngayinye ifunda izikhala zamakheli ezihlukile ngasikhathi sinye, kungenzeka iphutha lokufunda”. Imininingwane yodaba ingatholakala entweni 3.10 ku-ESP32 Series SoC Errata.
4. Kuthuthukiswe ukuzinza kwe-crystal oscillator okungu-32.768 KHz. Inkinga ibikwe iklayenti ukuthi kunethuba eliphansi lokuthi ku-hardware yokubuyekezwa kwe-chip v1.0, i-crystal oscillator engu-32.768 KHz ayikwazanga ukuqala kahle.
5. Izinkinga zomjovo we-Fault Fixed mayelana ne-boot evikelekile nokubethelwa kwe-flash zilungisiwe. Ireferensi: Ukwelulekwa Kwezokuphepha mayelana nomjovo wephutha nokuvikela kwe-eFuse (CVE-2019-17391) kanye Nokwelulekwa Kokuphepha kwe-Espressif Mayelana Nomjovo Wephutha kanye Ne-Secure Boot (CVE-2019-15894)
6. Ukuthuthukiswa: Kushintshwe izinga elincane le-baud elisekelwa imojuli ye-TWAI ukusuka ku-25 kHz ukuya ku-12.5 kHz.
7. Kuvunyelwe Imodi Yokuqalisa Yokulanda ukuthi ikhutshazwe unomphela ngokuhlela ibhithi entsha ye-eFuse UART_DOWNLOAD_DIS. Uma le bit ihlelelwe ku-1, Landa Imodi Yokuqalisa ayikwazi ukusetshenziswa futhi ukuqala kuzohluleka uma amaphinikhodi asethelwe le modi. Isoftware ihlela lokhu kancane ngokubhalela ku-bit 27 ye-EFUSE_BLK0_WDATA0_REG, futhi ifunde lokhu kancane ngokufunda i-bit 27 ye-EFUSE_BLK0_RDATA0_REG. Ukubhala okukhutshaziwe kwalokhu kuncishiswa kwabelwanwa nokukhubaza ukubhala kunkambu ye-flash_crypt_cnt eFuse.

Umthelela Kumaphrojekthi Ekhasimende

Lesi sigaba sihloselwe ukusiza amakhasimende ethu ukuthi aqonde umthelela wokusebenzisa i-chip revision v3.0 ekwakhiweni okusha noma ukufaka esikhundleni senguqulo endala ye-SoC nge-chip revision v3.0 ekwakhiweni okukhona.

Sebenzisa Ikesi 1: Izingxenyekazi zekhompuyutha kanye nokuthuthukiswa kwesofthiwe
Lesi yisimo lapho iphrojekthi entsha iqalwa khona noma ithuthukiswa ihadiwe nesoftware kuphrojekthi ekhona kuyindlela engenzeka. Esimeni esinjalo, iphrojekthi ingazuza ekuvikelekeni ekuhlaselweni komjovo wephutha futhi ingathatha i-advantage yendlela entsha yokuqalisa evikelekile kanye nokulungiswa kwesiphazamisi senqolobane ye-PSRAM ngokusebenza okuthuthukisiwe kwe-PSRAM.

1. Izinguquko Zedizayini Yezingxenyekazi zekhompuyutha:
   Sicela ulandele Imihlahlandlela yakamuva ye-ESP32 Hardware Design. Ukuze uthole ukwaziswa okwengeziwe nge-crystal oscillator engu-32.768 KHz, sicela ubhekisele ku-Section Crystal Oscillator ukuze uthole ulwazi olwengeziwe.
2. Izinguquko Zomklamo Wesoftware:
   1. Khetha Ukucushwa Okuncane ku-Rev3: Yiya ku-menuconfig > Ukuhlelwa kwe-Conponent > ESP32-specific, bese usetha inketho Yokubuyekeza I-ESP32 Esekelwe Ubuncane ibe "Rev 3".
   2. Inguqulo yesofthiwe: Ncoma ukusebenzisa i-boot evikelekile esekelwe e-RSA evela ku-ESP-IDF v4.1 nakamuva. Inguqulo yokukhishwa ye-ESP-IDF v3.X ingaphinda isebenze nohlelo lokusebenza nge-boot yoqobo evikelekile ye-V1.

Sebenzisa Ikesi 2: Ukuthuthukiswa Kwezingxenyekazi Zekhompyutha Kuphela
Lesi yisimo lapho amakhasimende enephrojekthi ekhona engavumela ukuthuthukiswa kwehadiwe kodwa isoftware idinga ukuhlala injalo kuzo zonke izibuyekezo zehadiwe. Kulokhu iphrojekthi ithola inzuzo yokuphepha ekuhlaselweni komjovo wephutha, ukulungiswa kwesiphazamisi senqolobane ye-PSRAM kanye nenkinga yokuqina kwe-crystal oscillator engu-32.768KHz. Ukusebenza kwe-PSRAM kuyaqhubeka nokufana nokho.

1. Izinguquko Zedizayini Yezingxenyekazi zekhompuyutha:
   Sicela ulandele Imihlahlandlela yakamuva ye-ESP32 Hardware Design.
2. Izinguquko Zomklamo Wesoftware:
   Iklayenti lingaqhubeka nokusebenzisa isofthiwe efanayo nomambambili kumkhiqizo osetshenzisiwe. I-binary application efanayo izosebenza kukho kokubili ukubuyekezwa kwe-chip v1.0 kanye nokubuyekezwa kwe-chip v3.0.
