Phetoho ea moralo ho ECO V3

Espressif e sa tsoa lokolla phetoho e le 'ngoe ea li-wafer-level ho ESP32 Series ea lihlahisoa (ECO V3). Tokomane ena e hlalosa phapang lipakeng tsa V3 le lintlafatso tsa pele tsa silicon tsa ESP32. Ka tlase ke liphetoho tsa mantlha tsa moralo ho ECO V3 Series ea lichifi:

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 ECO le Workarounds for Bugs.
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 ea 3.10 ho ESP32 ECO le Workarounds for Bugs.
3. E ntlafalitsoe 32.768 KHz crystal oscillator botsitso, taba e tlalehiloe ke moreki hore ho na le monyetla o tlase oa hore tlasa Hardware ea ECO V1, 32.768 KHz kristale oscillator ha e khone ho qala hantle.
4. 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)
5. Ntlafatso: E fetotse sekhahla sa bonyane ba baud se tšehetsoeng ke mojule oa CAN 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. 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 ECO V3 moahong o mocha kapa ho nkela mofuta oa khale oa SoC le ECO V3 moahong 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 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 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 IDF4.1 le hamorao. IDF3.X Release version e ka boela ea sebetsa le ts'ebeliso ka bootla ea V1 ea pele 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 Espressif 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. Sesebelisoa se tšoanang sa binary se tla sebetsa liphetolelong tsa chip tsa ECO V1 le V3.
