6. Download firmware into flash. For details, see the sections below.
7. After download, remove the jumper on IO0 and GND.
8. Power up the RF testing board again. The module will switch to working mode. The chip will read
programs from flash upon initialization.
Note:
IO0 is internally logic high. If IO0 is set to pull-up, the Boot mode is selected. If this pin is pull-down or left floating, the
Download mode is selected. For more information on ESP32-S3-WROOM-1 or ESP32-S3-WROOM-1U, please refer to

3.3 Set up Development Environment
The Espressif IoT Development Framework (ESP-IDF for short) is a framework for developing applications based
on the Espressif ESP32. Users can develop applications with ESP32-S3 in Windows/Linux/macOS based on
ESP-IDF. Here we take Linux operating system as an example.
3.3.1 Install Prerequisites
To compile with ESP-IDF you need to get the following packages:
• CentOS 7 & 8:
1
sudo yum -y update && sudo yum install git wget flex bison gperf python3 python3-
pip
2
python3-setuptools cmake ninja-build ccache dfu-util libusbx
• Ubuntu and Debian:
1
sudo apt-get install git wget flex bison gperf python3 python3-pip python3-
setuptools
2
cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0
• Arch:
1
sudo pacman -S --needed gcc git make flex bison gperf python-pip cmake ninja
ccache
2
dfu-util libusb
Note:
• This guide uses the directory
~
/esp on Linux as an installation folder for ESP-IDF.
• Keep in mind that ESP-IDF does not support spaces in paths.
3.3.2 Get ESPIDF
To build applications for ESP32-S3-WROOM-1 or ESP32-S3-WROOM-1U module, you need the software
libraries provided by Espressif in
.
To get ESP-IDF, create an installation directory (
~
/esp) to download ESP-IDF to and clone the repository with ‘git
clone’:
