Tsim Kev Hloov hauv Chip

Espressif tau tso tawm ESP32 nti hloov kho v3.0 uas nta wafer-theem hloov pauv raws li yav dhau los ESP32 nti hloov kho. Cov kev hloov pauv tsim tau nthuav tawm ntawm ESP32 nti hloov kho v3.0 yog:

1. Tsau "Vim lub sijhawm pib lub flash, ib qho kev saib xyuas rov pib dua tshwm sim thaum ESP32 yog lub zog los yog sawv los ntawm kev pw tsaug zog". Cov ntsiab lus ntawm qhov teeb meem tuaj yeem pom hauv cov khoom 3.8 hauv ESP32 Series SoC Errata.
2. PSRAM Cache Bug Kho: Kho "Thaum CPU nkag mus rau sab nraud SRAM hauv ib ntu, nyeem & sau ntawv yuam kev tuaj yeem tshwm sim". Cov ntsiab lus ntawm qhov teeb meem tuaj yeem pom hauv cov khoom 3.9 hauv ESP32 Series SoC Errata.
3. Tsau "Thaum txhua CPU nyeem qee qhov chaw nyob sib txawv ib txhij, kev nyeem ntawv yuam kev tuaj yeem tshwm sim". Cov ntsiab lus ntawm qhov teeb meem tuaj yeem pom hauv cov khoom 3.10 hauv ESP32 Series SoC Errata.
4. Optimized 32.768 KHz siv lead ua oscillator stability. Qhov teeb meem tau tshaj tawm los ntawm cov neeg siv khoom tias muaj qhov tshwm sim tsawg uas ntawm kev hloov kho chip v1.0 kho vajtse, 32.768 KHz siv lead ua oscillator tsis tuaj yeem pib zoo.
5. Kho Fault txhaj cov teeb meem hais txog kev ruaj ntseg khau raj thiab flash encryption yog tsau. Siv: Kev Tiv Thaiv Kev Ruaj Ntseg Txog Kev Txhaj Tshuaj Txhaum Cai thiab Kev Tiv Thaiv eFuse (CVE-2019-17391) & Espressif Security Advisory Txog Kev Txhaj Tshuaj Txhaum Cai thiab Kev Ruaj Ntseg (CVE-2019-15894)
6. Kev Txhim Kho: Hloov qhov tsawg kawg nkaus baud tus nqi txhawb los ntawm TWAI module los ntawm 25 kHz mus rau 12.5 kHz.
7. Tso cai rub tawm khau raj hom kom raug kaw mus tas li los ntawm kev ua haujlwm tshiab eFuse ntsis UART_DOWNLOAD_DIS. Thaum qhov no me ntsis programmed rau 1, Download Boot hom siv tsis tau thiab booting yuav ua tsis tau yog hais tias lub strapping pins teem rau hom no. Cov kev pab cuam software no me ntsis los ntawm kev sau ntawv rau me ntsis 27 ntawm EFUSE_BLK0_WDATA0_REG, thiab nyeem qhov no los ntawm kev nyeem me ntsis 27 ntawm EFUSE_BLK0_RDATA0_REG. Sau lov tes taw rau qhov me ntsis no tau muab qhia nrog kev sau tsis siv rau flash_crypt_cnt eFuse teb.

Kev cuam tshuam rau Cov Neeg Siv Khoom

Tshooj lus no yog npaj los pab peb cov neeg siv khoom kom nkag siab txog qhov cuam tshuam ntawm kev siv nti hloov kho v3.0 hauv kev tsim tshiab lossis hloov cov laus SoC nrog nti hloov kho v3.0 hauv cov qauv tsim uas twb muaj lawm.

Siv Case 1: Kho vajtse thiab Software upgrade
Qhov no yog qhov siv-qhov twg qhov project tshiab tab tom pib lossis hloov kho rau kho vajtse thiab software hauv qhov project uas twb muaj lawm yog qhov kev xaiv ua tau. Hauv qhov xwm txheej zoo li no, qhov project tuaj yeem tau txais txiaj ntsig los ntawm kev tiv thaiv kev txhaj tshuaj txhaum cai thiab tuaj yeem coj advantage ntawm kev ruaj ntseg khau raj tshiab thiab PSRAM cache kab laum kho nrog me ntsis txhim kho PSRAM kev ua tau zoo.

1. Hardware Design Hloov Hloov:
   Thov ua raws li ESP32 Hardware Design Guidelines tshiab. Rau 32.768 KHz crystal oscillator stability qhov teeb meem optimization, thov mus saib Tshooj Crystal Oscillator kom paub ntau ntxiv.
2. Software Design Hloov Hloov:
   1. Xaiv qhov tsawg kawg nkaus configuration rau Rev3: Mus rau menuconfig> Conponent config> ESP32-tshwj xeeb, thiab teeb tsa qhov tsawg kawg nkaus Txhawb ESP32 Kev Kho Mob rau "Rev 3".
   2. Software version: Pom zoo kom siv RSA-raws li kev ruaj ntseg khau raj los ntawm ESP-IDF v4.1 thiab tom qab ntawd. ESP-IDF v3.X Tso tawm version kuj tseem tuaj yeem ua haujlwm nrog daim ntawv thov nrog thawj khau raj ruaj ntseg V1.

Siv Case 2: Kho vajtse kho dua tshiab nkaus xwb
Qhov no yog qhov siv-qhov twg cov neeg siv khoom muaj qhov project uas twb muaj lawm uas tuaj yeem tso cai hloov kho kho vajtse tab sis software yuav tsum nyob twj ywm tib yam thoob plaws kho vajtse kho. Hauv qhov no, qhov project tau txais txiaj ntsig ntawm kev ruaj ntseg rau kev txhaj tshuaj txhaum cai, PSRAM cache kab laum kho thiab 32.768KHz siv lead ua oscillator teeb meem. PSRAM kev ua tau zoo tseem nyob li qub txawm tias.

1. Hardware Design Hloov Hloov:
   Thov ua raws li ESP32 Hardware Design Guidelines tshiab.
2. Software Design Hloov Hloov:
   Cov neeg siv khoom tuaj yeem txuas ntxiv siv tib lub software thiab binary rau cov khoom siv. Tib daim ntawv thov binary yuav ua haujlwm ntawm ob qho kev hloov kho nti v1.0 thiab nti hloov kho v3.0.
