ESPRESSIF ESP32 Chip Revision v3.0
Tsim Hloov Hauv Chip Hloov Kho v3.0
Espressif tau tso tawm ib qho kev hloov pauv wafer ntawm ESP32 Series ntawm cov khoom (chip kho v3.0). Cov ntaub ntawv no piav qhia qhov sib txawv ntawm kev hloov kho nti v3.0 thiab yav dhau los ESP32 nti hloov kho. Hauv qab no yog cov kev hloov pauv tseem ceeb hauv kev hloov kho nti v3.0:
- 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.
- Kho "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.
- Optimized 32.768 KHz siv lead ua oscillator ruaj khov, qhov teeb meem tau tshaj tawm los ntawm cov neeg siv khoom tias muaj qhov tshwm sim tsawg uas nyob rau hauv kev kho dua tshiab v1.0 kho vajtse, 32.768 KHz siv lead ua oscillator tsis tuaj yeem pib zoo.
- Fixed Fault txhaj cov teeb meem hais txog kev ruaj ntseg khau raj thiab flash encryption raug kho. 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 Ruaj Ntseg (CVE-2019-15894) - 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.
- 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. Software program no me ntsis los ntawm kev sau 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 ash_crypt_cnt eFuse.
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.
- Hardware Design Hloov Hloov:
Thov ua raws li Espressif Hardware Design Guideline tshiab. Rau 32.768 KHz crystal oscillator stability qhov teeb meem optimization, thov mus saib Tshooj Crystal Oscillator kom paub ntau ntxiv. - 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 fix thiab 32.768KHz crystal oscillator stability teeb meem. PSRAM kev ua tau zoo tseem nyob li qub txawm tias.
- Hardware Design Hloov Hloov:
Thov ua raws li qhov tseeb Espressif Hardware Design Guideline. - 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.
