scripts/sd_put.sh <file> [card path] sends a file (by default into /updates, for Update from SD) without taking the card out. The serial driver drops bytes once its receive buffer is full, so the transfer is stop-and-wait: 1 KB chunks, each acknowledged once the Storage Service has written it, into a 2 KB receive buffer. The device checks the SHA-256 before renaming <path>.part into place, and gives up after 5 s of silence or a card job that never returns. FileReceiver holds the logic, with 12 host tests. About 55 KB/s: 1.6 MB in under 30 s. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EhqxQ49eCju4CzKYNjZzwT

# 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)
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
sudo usermod -aG dialout "$USER"
|
|
```
|
|
|
|
## Firmware Updates over Wi-Fi (OTA)
|
|
|
|
Once the Cardputer runs an OTA-capable firmware (flashed once over USB), updates can go over Wi-Fi:
|
|
|
|
```sh
|
|
scripts/ota_keygen.sh # once: creates the signing key (see ADR 0003)
|
|
scripts/flash.sh --ota 10.39.39.12 # build, sign and push; or set RORO_OTA_HOST
|
|
```
|
|
|
|
The device shows the push address in **Settings → Firmware**. It installs a correctly signed update right away, restarts (waiting up to 60 s if you're typing), and runs the new firmware on **Probation**. If the new firmware crashes, or can't reconnect Wi-Fi within 3 minutes, it rolls back to the previous one and says so.
|
|
|
|
To install from the SD card instead, copy the `.ota` file from `.pio/build/cardputer-adv/` into `/updates` on the card, then use **Settings → Firmware**. With the Cardputer on USB, the card can stay in: `scripts/sd_put.sh <file.ota>` sends it over the serial console into `/updates` (about 30 s for 1.6 MB, checked with SHA-256 before it's renamed into place; `SD_PUT_DEBUG=1` shows the console while it runs).
|
|
|
|
**The private key** lives in `~/.config/roro9stack/ota-key.pem` and must never be committed. If it's lost, generate a new pair and flash once over USB.
|
|
|
|
## Development aids
|
|
|
|
`scripts/serial_log.sh [seconds] [command…]` records the serial output, and can send commands to the firmware first. For example, `scripts/serial_log.sh 30 short sleep:12 burst` sets short screen timeouts, waits 12 s, then sends a burst of Toasts.
|
|
|
|
| Command | Effect |
|
|
|---|---|
|
|
| `burst` | Publishes 5 Notifications at once |
|
|
| `key up\|down\|left\|right\|select\|back\|home`, or `key <char>` | Injects a key press |
|
|
| `sound on` / `sound off` | Toggles the Sound setting (beep + LED) |
|
|
| `short` / `normal` | Screen timeouts 5 s / 10 s, or 30 s / 60 s |
|
|
| `wifi add <ssid><TAB><password>` | Adds a Saved Network (so credentials stay out of the repo) |
|
|
| `log <text>` | Appends a line to a test IRC Log (`/irc/dev/#test/<date>.log`) |
|
|
| `sd list` | Lists the files of each Storage Clean-up category |
|
|
| `cat <path>` | Prints the first ~1.2 KB of a file on the SD card |
|
|
| `irc start` | Starts the IRC Service (normally done by opening the IRC App) |
|
|
| `irc say <buffer> <text>` | Types into a Buffer, commands included (`irc say 0 /join #test`) |
|
|
| `irc dump` | Prints IRC status, memory, and the last lines of each Buffer |
|
|
| `wifi status` | Prints Wi-Fi state, network, signal, clock and free heap |
|
|
|
|
`scripts/flash.sh` stops a running serial log first, since it would hold the port.
