Liphetoho tsa moralo ho Chip

Espressif e lokolitse ESP32 chip revision v3.0 e nang le liphetoho tsa boemo ba wafer tse ipapisitseng le lintlafatso tse fetileng tsa ESP32. Liphetoho tsa moralo tse hlahisitsoeng ho ESP32 chip revision v3.0 ke:

1. E tsitsitse "Ka lebaka la nako ea ho qala ha flash, ts'ebetso ea bohata ea "watchdog reset" e etsahala ha ESP32 e tsosoa kapa e tsoha ho tloha Borokong bo tebileng". Lintlha tsa taba li ka fumanoa ho ntlha ea 3.8 ho ESP32 Series SoC Errata.
2. PSRAM Cache Bug Fix: E tsitsitse "Ha CPU e fihlella SRAM e kantle ka tatellano e itseng, ho ka etsahala liphoso tsa ho bala le ho ngola". Lintlha tsa taba li ka fumanoa ho ntlha ea 3.9 ho ESP32 Series SoC Errata.
3. E tsitsitse "Ha CPU e 'ngoe le e' ngoe e bala libaka tse fapaneng tsa liaterese ka nako e le 'ngoe, phoso ea ho bala e ka etsahala". Lintlha tsa taba li ka fumanoa ho ntlha 3.10 ho ESP32 Series SoC Errata.
4. E ntlafalitsoe 32.768 KHz kristale oscillator botsitso. Taba ena e tlalehiloe ke moreki hore ho na le monyetla o tlase oa hore ho chip revision v1.0 hardware, 32.768 KHz crystal oscillator ha e khone ho qala hantle.
5. Litaba tse tsitsitseng tsa ente ea Fault mabapi le boot e sireletsehileng le encryption ea flash li tsitsitse. Reference: Keletso ea Ts'ireletso mabapi le ente ea phoso le ts'ireletso ea eFuse (CVE-2019-17391) & Keletso ea Tšireletso ea Espressif Mabapi le Ente ea Phoso le Boot e Sireletsehileng (CVE-2019-15894)
6. Ntlafatso: E fetotse sekhahla sa bonyane ba baud se tšehetsoeng ke mojule oa TWAI ho tloha ho 25 kHz ho ea ho 12.5 kHz.
7. E lumelletsoe ho Koaheloa ka Boot mode ho tingoa ka ho sa feleng ka ho etsa lenaneo le lecha la eFuse UART_DOWNLOAD_DIS. Ha karolo ena e hlophiselitsoe ho 1, Khoasolla Boot mode e ke ke ea sebelisoa 'me booting e tla hloleha haeba likhoele tsa likhoele li behiloe molemong ona. Mananeo a software hanyane ka ho ngolla ho bit 27 ea EFUSE_BLK0_WDATA0_REG, mme o bala hanyane ka ho bala bit 27 ea EFUSE_BLK0_RDATA0_REG. Ho thibela ho ngola bakeng sa karolo ena ho arolelanoa le ho thibela ho ngola bakeng sa lebala la flash_crypt_cnt eFuse.

Tšusumetso ho Merero ea Bareki

Karolo ena e reretsoe ho thusa bareki ba rona ho utloisisa phello ea ho sebelisa chip revision v3.0 moahong o mocha kapa ho nkela mofuta oa khale oa SoC sebaka ka chip revision v3.0 moetsong o teng.

Sebelisa Taba ea 1: Hardware le Software Upgrade
Ena ke boemo ba tšebeliso moo projeke e ncha e qalisoang kapa ho ntlafatsoa bakeng sa Hardware le software morerong o teng ke khetho e ka khonehang. Boemong bo joalo, morero o ka rua molemo ka tšireletso khahlanong le tlhaselo ea ente ea phoso 'me e ka boela ea nka advantage ea mochini o mocha o sireletsehileng oa bootle le tokiso ea cache ea PSRAM e nang le ts'ebetso e ntlafalitsoeng hanyane ea PSRAM.

1. Liphetoho tsa Hardware Design:
   Ka kopo latela Litaelo tsa Moralo oa Hardware tsa ESP32 tsa morao-rao. Bakeng sa 32.768 KHz crystal oscillator stability issue optimization, ka kopo sheba Section Crystal Oscillator bakeng sa boitsebiso bo eketsehileng.
2. Liphetoho tsa Moralo oa Software:
   1. Kgetha Minimum configuration to Rev3: Eya ho menuconfig > Conponent config > ESP32-spesfic, mme o sete kgetho ya Minimum Supported ESP32 Revision ho "Rev 3".
   2. Software version: Khothalletsa ho sebelisa RSA-based secure boot boot from ESP-IDF v4.1 le hamorao. Mofuta oa tokollo oa ESP-IDF v3.X o ka sebetsa le ts'ebeliso ka bootla ea V1 ea mantlha e sireletsehileng.

Sebelisa Taba ea 2: Ntlafatso ea Hardware Feela
Ena ke taba ea ts'ebeliso moo bareki ba nang le projeke e teng e ka lumellang ntlafatso ea Hardware empa software e hloka ho lula e ts'oana ho lintlafatso tsa Hardware. Tabeng ena morero o fumana molemo oa tšireletso ho litlhaselo tsa ente ea phoso, PSRAM cache bug fix le 32.768KHz crystal oscillator taba ea botsitso. Ts'ebetso ea PSRAM e ntse e tsoela pele ho lula e le joalo.

1. Liphetoho tsa Hardware Design:
   Ka kopo latela tataiso ea morao-rao ea ESP32 Hardware Design.
2. Liphetoho tsa Moralo oa Software:
   Moreki a ka tsoela pele ho sebelisa software e tšoanang le binary bakeng sa sehlahisoa se rometsoeng. E tšoanang kopo binary tla sebetsa ka bobeli chip revision v1.0 le chip revision v3.0.
