probe-rs
The probe-rs project is a set of tools to interact with embedded MCU's using various debug probes. It is similar to openOCD, PyOCD, Segger tools, etc. There is support for ARM & RISCV architectures along with a collection of tools, including but not limited to:
- Debugger
- GDB support.
- CLI for interactive debugging.
- VSCode extension.
- RTT (Real Time Transfer)
- Similar to app_trace component of IDF.
- Flashing algorithms
More info about probe-rs & how to set up a project can be found on the probe.rs website.
USB-JTAG-SERIAL peripheral for ESP32-C3
Starting from probe-rs v0.12, it is possible to flash and debug the ESP32-C3 with the builtin USB-JTAG-SERIAL peripheral, no need for any external hardware debugger. More info on configuring the interface can be found in the official documentation.
Support for Espressif chips
probe-rs currently only supports ARM & RISC-V, therefore this limits the number of Espressif chips that can be used at the moment.
| Chip | Flashing | Debugging |
|---|---|---|
| ESP32-C3 | ✅ | ⚠️ |
Note: Items marked with ⚠️ are currently work in progress, usable but expect bugs.
Permissions - Linux
On Linux, you may run into permission issues trying to interact with Espressif probes. Installing the following udev rules and reloading should fix that issue.
# Espressif dev kit FTDI
