roro9stack

A multi-app firmware for the M5Stack Cardputer ADV with the Cap LoRa-1262. It's a Meshtastic-compatible mesh messenger, plus Wi-Fi tools, IRC, GNSS and more. Licensed GPL-3.0.

Requirements

Only Docker is needed. PlatformIO and the ESP32 toolchain run inside a container, and are cached in the roro9stack-pio Docker volume. The first build downloads about 1 GB and takes a few minutes.

Build and test (local CI)

scripts/ci.sh

This runs the host-side unit tests (test/, native environment), then builds the firmware. The output is .pio/build/cardputer-adv/firmware.factory.bin.

Flash

  1. Connect the Cardputer by USB-C.

  2. Run:

    scripts/flash.sh            # auto-detects the port; or: scripts/flash.sh /dev/ttyACM1
    

    This uploads the firmware, then opens the serial monitor. Quit the monitor with Ctrl+C.

If the upload can't connect, put the device in download mode: hold G0 (the button next to the screen) while plugging in USB, or while pressing reset. Then retry.

If you get "permission denied" on the port, your user needs access to the serial device. Run this once, then log out and back in:

sudo usermod -aG dialout "$USER"
