ESPRESSIF ESP32 Chip Revision v3.0

Phetoho ea Moralo ho Chip Revision v3.0

Espressif e lokolotse phetoho e le 'ngoe ea li-wafer-level ho ESP32 Series ea lihlahisoa (chip revision v3.0). Tokomane ena e hlalosa phapang lipakeng tsa chip revision v3.0 le liphetoho tse fetileng tsa ESP32 chip. Ka tlase ke liphetoho tsa mantlha tsa moralo ho chip revision v3.0:

1. PSRAM Cache Bug Fix: E tsitsitse "Ha CPU e fihlella SRAM ea 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.
2. E tsitsitse "Ha CPU e 'ngoe le e' ngoe e bala libaka tse fapaneng tsa liaterese ka nako e le 'ngoe, ho ka etsahala phoso ea ho bala." Lintlha tsa taba li ka fumanoa ho ntlha 3.10 ho ESP32 Series SoC Errata.
3. E ntlafalitsoe 32.768 KHz crystal oscillator botsitso, taba e ile ea tlalehoa ke moreki hore ho na le monyetla o tlase oa hore tlas'a chip revision v1.0 hardware, 32.768 KHz crystal oscillator ha e khone ho qala hantle.
4. Litaba tse tsitsitseng tsa ente ea Fault mabapi le boot e sireletsehileng le encryption ea flash lia lokisoa. Reference: Keletso ea Tšireletso mabapi le ente ea phoso le tšireletso ea eFuse
   (CVE-2019-17391) & Keletso ea Tšireletso ea Espressif Mabapi le Ente ea Phoso le Boot e sireletsehileng (CVE-2019-15894)
5. 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.
6. 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. Lenaneo la software hanyane ka ho ngolla bit 27 ea EFUSE_BLK0_WDATA0_REG, 'me u bale hanyane ka ho bala bit 27 ea EFUSE_BLK0_RDATA0_REG. Write Disable bakeng sa karolo ena e arolelanoa le write disable bakeng sa sh_crypt_cnt eFuse field.

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 tšireletsong khahlanong le tlhaselo ea ente ea phoso 'me e ka boela ea nka nakotage ea mochini o mocha o sireletsehileng oa boot le tokiso ea cache ea PSRAM e nang le ts'ebetso e ntlafalitsoeng hanyane ea PSRAM.

1. Liphetoho tsa Hardware Design:
   Ka kopo latela tataiso ea morao-rao ea Espressif Hardware Design. 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 Bonnyane ba tlhophiso ho Rev3: Eya ho menuconfig > Conponent config > ESP32-spesfic, mme o sete kgetho ya Minimum Supported ESP32 Revision ho "Rev 3".
   2) Mofuta oa software: Khothalletsa ho sebelisa bootle e sireletsehileng e thehiloeng ho RSA ho tsoa ho 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 bakeng sa 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 Espressif Hardware Design.
2. Liphetoho tsa Moralo oa Software:
   Moreki a ka tsoela pele ho sebelisa software e tšoanang le binary bakeng sa lihlahisoa tse rometsoeng. E tšoanang kopo binary tla sebetsa ka bobeli chip revision v1.0 le chip revision v3.0.
