Mgbanwe imewe na ECO V3

Espressif ewepụtala otu mgbanwe ọkwa wafer na nso nso a na ngwaahịa ESP32 Series (ECO V3). Akwụkwọ a na-akọwa ọdịiche dị n'etiti V3 na nlegharị anya silicon wafer ESP32 gara aga. N'okpuru bụ isi mgbanwe imewe na ECO V3 Series nke ibe:

PSRAM Cache Bug Fix: Edobere "Mgbe CPU nwetara SRAM mpụga n'usoro ụfọdụ, agụ & dee njehie nwere ike ime." Enwere ike ịchọta nkọwa nke okwu a na ihe 3.9 na ESP32 ECO na Workarounds for Bugs.
Edobere "Mgbe CPU ọ bụla na-agụ ụfọdụ oghere adreesị dị iche iche n'otu oge, njehie ọgụgụ nwere ike ime." Enwere ike ịchọta nkọwa nke okwu a na ihe 3.10 na ESP32 ECO na Workarounds for Bugs.

Nkwụsi ike 32.768 KHz kristal oscillator, onye ahịa kọrọ okwu a na enwere ike dị ala na n'okpuru ngwa ECO V1, oscillator kristal 32.768 KHz enweghị ike ịmalite nke ọma.
A na-edozi nsogbu ịgba ntụtụ ezighi ezi gbasara buut echedoro na nzuzo nzuzo. Ntụaka: Ndụmọdụ nchekwa gbasara ntụtụ mmejọ na nchekwa eFuse (CVE-2019-17391) & Ndụmọdụ Nchekwa Espressif gbasara mgbanye mmejọ na buut echekwara (CVE-2019-15894)

Mmetụta na ọrụ ndị ahịa

Ezubere ngalaba a iji nyere ndị ahịa anyị aka ịghọta mmetụta nke iji ECO V3 n'ime ihe ọhụrụ ma ọ bụ dochie ụdị SoC ochie na ECO V3 n'ime imewe dị adị.

Jiri ikpe 1: nkwalite ngwaike na ngwanrọ
Nke a bụ ihe eji eme ihe ebe a na-amalite ọrụ ọhụrụ ma ọ bụ kwalite maka ngwaike na ngwanrọ na ọrụ dị adị bụ nhọrọ enwere ike. N'ọnọdụ dị otú ahụ, oru ngo nwere ike irite uru site na nchebe megide mmejọ injection ọgụ na nwekwara ike na-advantage nke usoro buut ọhụrụ echekwara yana ndozi ebe nchekwa nchekwa PSRAM nwere arụmọrụ PSRAM nwetụrụ ntakịrị.

Mgbanwe nhazi ngwaike:
Biko soro ntuziaka imewe ngwaike Espressif kacha ọhụrụ. Maka njikarịcha okwu nkwụsi ike kristal oscillator 32.768 kHz, biko rụtụ aka na ngalaba Crystal Oscillator maka ozi ndị ọzọ.
Mgbanwe Nhazi Software:
1. Họrọ Nhazi kacha nta na Rev3: Gaa na menuconfig> Conponent config> ESP32-kpọmkwem, ma tọọ Ntụgharị ESP32 kacha nta akwadoro ka ọ bụrụ “Nkpughe 3”.
2. Ụdị ngwanro: Kwadoro ka ijiri akpụkpọ ụkwụ echekwara RSA sitere na IDF4.1 na emesia. Ụdị mwepụta IDF3.X nwekwara ike ịrụ ọrụ na ngwa nwere buut mbụ echedoro V1.

Jiri ikpe 2: naanị nkwalite ngwaike
Nke a bụ ihe eji eme ebe ndị ahịa nwere ọrụ dị adị nke nwere ike inye ohere nkwalite ngwaike mana sọftụwia kwesịrị ka ọ dịrị n'otu n'ofe ngbanwe ngwaike. N'okwu a, oru ngo a na-enweta uru nke nchekwa na mwakpo injection kpatara, PSRAM cache bug fix na 32.768KHz crystal oscillator nkwụsi ike. Nrụ ọrụ PSRAM na-aga n'ihu na-adị otu.

Mgbanwe nhazi ngwaike:
Biko soro ntuziaka imewe ngwaike Espressif kacha ọhụrụ.

Mgbanwe Nhazi Software:
Onye ahịa nwere ike ịga n'ihu na-eji otu ngwanrọ na ọnụọgụ abụọ maka ngwaahịa ebugara. Otu ọnụọgụ abụọ ngwa ga-arụ ọrụ na ụdị mgbawa ECO V1 na V3.
