Canje-canjen ƙira a cikin Chip

Espressif ya fito da ESP32 guntu bita v3.0 wanda ke fasalta canje-canjen matakin wafer dangane da bitar guntuwar ESP32 da ta gabata. Canje-canjen ƙira da aka gabatar akan ESP32 guntu bita v3.0 sune:

1. Kafaffen "Saboda lokacin farawa na walƙiya, sake saiti mai ban tsoro yana faruwa lokacin da aka kunna ESP32 ko kuma ya tashi daga barci mai zurfi". Ana iya samun cikakkun bayanai game da batun a abu na 3.8 a cikin ESP32 Series SoC Errata.
2. PSRAM Cache Bug Gyara: Kafaffen "Lokacin da CPU ya sami dama ga SRAM na waje a cikin wani jeri, karanta & rubuta kurakurai na iya faruwa". Ana iya samun cikakkun bayanai game da batun a abu na 3.9 a cikin ESP32 Series SoC Errata.
3. Kafaffen "Lokacin da kowane CPU ya karanta wasu wuraren adireshi daban-daban lokaci guda, kuskuren karantawa na iya faruwa". Ana iya samun cikakkun bayanai game da batun a abu na 3.10 a cikin ESP32 Series SoC Errata.
4. Ingantacciyar 32.768 KHz crystal oscillator kwanciyar hankali. Abokin ciniki ya ruwaito batun cewa akwai ƙananan yuwuwar cewa akan kayan aikin v1.0 na guntu, 32.768 kHz crystal oscillator ba zai iya farawa da kyau ba.
5. Kafaffen al'amurran allura na kuskure game da amintaccen taya da ɓoye walƙiya an gyara su. Magana: Shawarar Tsaro game da allurar kuskure da kariyar eFuse (CVE-2019-17391) & Shawarar Tsaro ta Espressif Game da Injection Laifi da Tabbataccen Boot (CVE-2019-15894)
6. Ingantawa: Canja mafi ƙarancin ƙimar baud da ke tallafawa tsarin TWAI daga 25 kHz zuwa 12.5 kHz.
7. An ba da izinin Zazzage Yanayin Boot don a kashe shi ta dindindin ta tsara sabon eFuse bit UART_DOWNLOAD_DIS. Lokacin da aka tsara wannan bit zuwa 1, Zazzage yanayin Boot ba za a iya amfani da shi ba kuma booting zai gaza idan an saita fil ɗin madauri don wannan yanayin. Software yana tsara wannan bit ta hanyar rubuta zuwa bit 27 na EFUSE_BLK0_WDATA0_REG, kuma karanta wannan bit ta hanyar karanta bit 27 na EFUSE_BLK0_RDATA0_REG. Rubutun kashewa don wannan bit ɗin ana rabawa tare da kashe rubutu don filin flash_crypt_cnt eFuse.

   2. Sigar software: Ba da shawarar yin amfani da amintaccen taya na tushen RSA daga ESP-IDF v4.1 da kuma daga baya. Sigar Sakin ESP-IDF v3.X kuma na iya aiki tare da aikace-aikace tare da amintaccen boot V1 na asali.

Yi amfani da Case 2: Haɓaka Hardware Kawai
Wannan shine shari'ar amfani inda abokan ciniki ke da aikin da ke akwai wanda zai iya ba da damar haɓaka kayan masarufi amma software tana buƙatar kasancewa iri ɗaya a cikin bita na hardware. A wannan yanayin aikin yana samun fa'idar tsaro ga harin allura da kuskure, PSRAM cache bug fix da 32.768KHz crystal oscillator kwanciyar hankali. Ayyukan PSRAM na ci gaba da kasancewa ɗaya ko da yake.
