Hi everyone,

Espressif can you check if the ESP32 Boot Mode is correct ? (it is extracted from different document / source code)

  • esp_wroom_32_datasheet_en.pdf => Table 4: Strapping Pins
  • esp32_datasheet_en_0-1.pdf => §2.4 Strapping Pins

Any feedback is welcome especially for SDIO Slave Download Mode V2 & SDIO Slave Download Mode V1.1
If you have more details on those mode it will be great too
