Kusintha kwa Design mu Chip

Espressif yatulutsa ESP32 chip revision v3.0 yomwe imakhala ndi masinthidwe awafer-level kutengera kusinthidwa kwa chipangizo cha ESP32. Zosintha zamapangidwe zomwe zidayambitsidwa pa ESP32 chip revision v3.0 ndi:

1. Zokhazikika "Chifukwa cha nthawi yoyambira, kukonzanso kwaposachedwa kwa ulonda kumachitika ESP32 ikayatsidwa kapena kudzuka kuchokera ku Deep-sleep". Tsatanetsatane wa nkhaniyi angapezeke mu chinthu 3.8 mu ESP32 Series SoC Errata.
2. PSRAM Cache Bug Fix: Yokhazikika "CPU ikafika ku SRAM yakunja motsatizana, zolakwika zowerengera ndi kulemba zitha kuchitika". Tsatanetsatane wa nkhaniyi angapezeke mu chinthu 3.9 mu ESP32 Series SoC Errata.
3. Zokhazikika "CPU iliyonse ikawerenga malo ena adilesi nthawi imodzi, cholakwika chowerenga chikhoza kuchitika". Tsatanetsatane wa nkhaniyi angapezeke mu chinthu 3.10 mu ESP32 Series SoC Errata.
4. Kukhazikika kwa 32.768 KHz crystal oscillator. Nkhaniyi idanenedwa ndi kasitomala kuti pali mwayi wochepa kuti pa chip revision v1.0 hardware, 32.768 KHz crystal oscillator sakanakhoza kuyamba bwino.
5. Nkhani zokhazikika za jakisoni wa Fault zokhudzana ndi boot yotetezedwa ndi kubisa kwa flash ndizokhazikika. Upangiri: Upangiri Wachitetezo wokhudza jakisoni wolakwa ndi chitetezo cha eFuse (CVE-2019-17391) & Upangiri wa Chitetezo cha Espressif Okhudza Kujambulitsa Kolakwa ndi Kutetezedwa Kwa Boot (CVE-2019-15894)
6. Kupititsa patsogolo: Anasintha kuchuluka kwa baud komwe kumathandizidwa ndi gawo la TWAI kuchokera ku 25 kHz kupita ku 12.5 kHz.
7. Lolani Kutsitsa Boot mode kuyimitsidwa kotheratu pokonza pulogalamu ya eFuse bit UART_DOWNLOAD_DIS. Izi zikakonzedwa kukhala 1, Tsitsani Mawonekedwe a Boot sangathe kugwiritsidwa ntchito ndipo kuwotcha kungalephereke ngati zikhomo zakhazikitsidwa mwanjira iyi. Mapulogalamu apakompyuta pang'onopang'ono polemba ku bit 27 ya EFUSE_BLK0_WDATA0_REG, ndikuwerenga pang'onopang'ono powerenga bit 27 ya EFUSE_BLK0_RDATA0_REG. Kuletsa kulemba kwapang'onopang'onoku kumagawidwa ndi kulemba disable pagawo la flash_crypt_cnt eFuse.

Impact pa Customer Projects

Gawoli cholinga chake ndi kuthandiza makasitomala athu kumvetsetsa momwe chip revision v3.0 imakhudzira mamangidwe atsopano kapena kusintha mtundu wakale wa SoC ndi chip revision v3.0 pamapangidwe omwe alipo.

Gwiritsani Mlandu 1: Kusintha kwa Hardware ndi Mapulogalamu
Umu ndi momwe pulojekiti yatsopano ikuyambitsidwira kapena kukweza kwa hardware ndi mapulogalamu mu polojekiti yomwe ilipo ndi njira yotheka. Zikatero, pulojekitiyo imatha kupindula ndi chitetezo ku chiwopsezo cha jekeseni wolakwika komanso imatha kutenga advantage ya makina atsopano otetezedwa otetezedwa ndi PSRAM cache bug kukonza ndikuchita bwino pang'ono kwa PSRAM.

1. Kusintha kwa Hardware Design:
   Chonde tsatirani malangizo aposachedwa a ESP32 Hardware Design. Pakukhathamiritsa kwa vuto la crystal oscillator 32.768 KHz, chonde onani Gawo Crystal Oscillator kuti mumve zambiri.
2. Kusintha kwa Mapangidwe a Mapulogalamu:
   1. Sankhani Kusintha Kocheperako ku Rev3: Pitani ku menuconfig> Conponent config> ESP32-specific, ndikukhazikitsa njira ya Minimum Supported ESP32 Revision kuti "Rev 3".
   2. Mtundu wa mapulogalamu: Ndibwino kuti mugwiritse ntchito jombo lotetezedwa la RSA kuchokera ku ESP-IDF v4.1 ndi mtsogolo. Mtundu wa ESP-IDF v3.X Wotulutsidwa ungathenso kugwira ntchito ndi pulogalamu yokhala ndi boot yotetezedwa yoyambirira ya V1.

Gwiritsani Mlandu Wachiwiri: Kusintha Kwa Hardware Pokha
Izi ndizomwe zimagwiritsidwa ntchito pomwe makasitomala ali ndi pulojekiti yomwe ilipo yomwe ingalole kukweza kwa hardware koma mapulogalamu ayenera kukhala ofanana pakusintha kwa hardware. Pachifukwa ichi, polojekitiyi imapindula ndi chitetezo cha jekeseni wolakwika, PSRAM cache bug fix ndi 32.768KHz crystal oscillator stability issue. Ntchito ya PSRAM ikupitilirabe chimodzimodzi.

1. Kusintha kwa Hardware Design:
   Chonde tsatirani malangizo aposachedwa a ESP32 Hardware Design.
2. Kusintha kwa Mapangidwe a Mapulogalamu:
   Makasitomala atha kupitiliza kugwiritsa ntchito mapulogalamu omwewo ndi binary pazinthu zomwe zatumizidwa. Ntchito yofananira ya binary idzagwiranso ntchito pa chip revision v1.0 ndi chip revision v3.0.
