Update: ESP32-S3-WROOM-1 and -2 have exactly the same SPI wording in their respective datasheets. No mention is made of V2 having extra capabilities over V1. https://www.espressif.com/sites/default/files/documentation/esp32-s3-wroom-2_datasheet_en.pdf https://www.espressif.com/sites/default/files/do...

This table (https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/protocols/esp_spi_slave_protocol.html) says that an ESP32-S3 v2 will do the SPI Slave Half Duplex protocol. Does that mean that v1 will not ? How does one tell if a processor is v1 or v2 ? When did the changeover f...

It turns out that the problem is the ESP32 WROOM board I am using don't support JTAG debugging via the USB interface. It only supports the uploading of code. The key piece of information in this regard is that the USB interface on my board is Silicon Labs CP210x UART Bridge . The usual USB device th...

You need to connect a debug probe to the jtag pins, see https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-guides/jtag-debugging/configure-ft2232h-jtag.html So there is no way to debug an ESP32-WROOM* without using a separate JTAG device ? The on board USB interface allows for flashing...

What do you mean by the "in the "blink-led" location instead of main" ? Are you not running this command in a terminal window in VSCode ?

The eFuses have never been touched on this processor and I've been able to flash it with other IDE/toolchains.

What isn't working ?

See attached output of ESP-IDF Doctor.

Do you want the log file or just the first part ?
