Overview

Initial dev environment setup for ESP32-C3 and ESP32-C6 programming, tailored towards Rust development. Some of this will also apply to the ESP32-C2 as well as the ESP32-H2 and ESP32-P4 when they are released.

1. General Setup
2. Setup USB JTAG
3. Setup GPIO JTAG

General Setup

• Install ESP tooling:

Problem:

You don't have permissions to read from or write to a USB tty device. This can manifest in a variety of ways.

Solution: Write a udev rule for your tty device:

1. Identify the tty device:

   Run ls /dev/. The device will show up as a /dev/ttyACMx or /dev/ttyUSBx where x is some positive whole number.

   If there are multiple ACM and/or USB devices, unplug and re-plug in the USB device. Then, search for the USB event in the kernel message buffer using the following command: sudo dmesg | grep "usb". This should print out enough information to where you can identify the desired USB tty.

Raspberry Pi Picoprobe Debug Setup/Tips & Tricks

This document details useful information on how to use a Raspberry Pi Pico as a SWD probe for another Pico using the Picoprobe software. This information assumes you have followed all of the steps in Appendix A of the Getting Started with Raspberry Pi Pico Guide and that you are doing development on a Linux system.

Essential Setup

1. Add the below files to your system to enable non-root access to the devices

   /etc/udev/rules.d/99-openocd.rules:

   # Raspberry Pi Picoprobe
   

ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="0004", MODE="0666"
