Thanks for A2A! Before providing the actual steps which needs to be followed, I would very briefly define some terms for people new to this - What is ESP32 ? ESP32 is a series of low-power programmable devices (basically system on a chip microcont. To put the chip in the bootloader mode, we need to hold the BOOT pin (GPIO0), grounded while grounding and releasing the RESET pin (EN). The ESP32 boards often use the internal GPIO pin numbering on the board, this means that you don't have to worry about other kinds of pin numberings, yay! Some notes about the pins on the ESP32: GPIO0 is used to determine the boot mode on startup. WROVER earlier than ESP32-WROVER-B use 1. "With this, I can program and debug the ESP32 in one step. You can follow below steps to fix this problem. External flash & SRAM: ESP32 supports up to four 16 MB external QSPI flashes and SRAMs with hardware encryption based on AES to protect developers' programs and data.
