A Zig-based embedded development tool for debugging and programming microcontrollers. The goal is to provide a probe-rs equivalent written in Zig, though it's currently a work in progress.

• Debug Probe Support: Connects to CMSIS-DAP compatible debug probes via USB
• Flash Programming: Load ELF binaries onto microcontroller targets with integrated flash algorithms
• Target Control: Halt, run, reset, and interact with ARM Cortex-M based targets
• RTT (Real-Time Transfer): Stream real-time logs and debug output from running embedded applications
• Memory Operations: Read and write memory at arbitrary addresses on target devices

• RP2040 (Raspberry Pi Pico and compatible boards)
• RP2350 (Raspberry Pi Pico 2 and compatible boards) (only arm for now)

• ARM Debug Interface (Cortex-M)
• CMSIS-DAP probes

# List in text format (default)
zprobe list chips

# List in JSON format
zprobe list chips --format json

# List in ZON format
zprobe list chips --format zon

zprobe list probes

Load and execute an ELF file on a target microcontroller:

# Basic usage (requires --chip option)
zprobe load --chip RP2040 firmware.elf

# Specify protocol speed
zprobe load --chip RP2040 --speed 1MHz firmware.elf
zprobe load --chip RP2040 --speed 100kHz firmware.elf

# Choose how to run the binary
zprobe load --chip RP2040 --run-method call_entry firmware.elf  # Call entry point
zprobe load --chip RP2040 --run-method reboot firmware.elf      # Reboot system

# Enable RTT logging after loading
zprobe load --chip RP2040 --rtt firmware.elf

• -h, --help: Display help information

List available probes or supported chips.

zprobe list [OPTIONS] <REQUEST>

Options:

• --format <FORMAT>: Output format (text, json, zon). Default: text
• <REQUEST>: What to list (probes, chips)

Load an ELF file onto a target microcontroller.

zprobe load [OPTIONS] <ELF_FILE>

Options:

• --speed <SPEED>: Protocol speed (e.g., 10MHz, 100kHz). Default: 10MHz
• --chip <CHIP>: Target chip (required). Use zprobe list chips to see available chips
• --run-method <RUN>: How to execute the binary (call_entry, reboot)
• --rtt: Print RTT logs after loading the image
• <ELF_FILE>: Path to the ELF binary to load
