Operate BashGym training, evaluation, and durable AutoResearch from Codex, Claude Code, Hermes, or another compatible agent. Use for guided campaign preparation and resumption, ML session planning, preflight, goals and KPIs, model training or fine-tuning, runtime monitoring, evaluation and benchmark comparison, report generation, bounded iteration, and curated GBrain updates across embedding, SFT, DPO, GRPO/RLVR, LoRA/QLoRA, distillation, and full-model workflows.
Generate synthetic training data, manage seeds, preview synthesis jobs, and work with the data factory. Use when asked to generate synthetic data, create training examples, augment a dataset, manage seeds, or check factory job status.
Browse, compare, evaluate, and manage trained models. View leaderboard, trends, lineage, and artifacts. Deploy models to Ollama. Use when asked about models, model comparison, which model is best, model evaluation, deploying a model, or downloading a model.

Use the i2c and spi tools to interact with sensors, displays, and other peripherals connected to the board.
# 1. Find available buses
i2c detect
# 2. Scan for connected devices
i2c scan (bus: "1")
# 3. Read from a sensor (e.g. AHT20 temperature/humidity)
i2c read (bus: "1", address: 0x38, register: 0xAC, length: 6)
# 4. SPI devices
spi list
spi read (device: "2.0", length: 4)
Most I2C/SPI pins are shared with WiFi on Sipeed boards. You must configure pinmux before use.
See references/board-pinout.md for board-specific commands.
Common steps:
/etc/init.d/S30wifi stopmodprobe i2c-devdevmem (board-specific)i2c detect and i2c scanconfirm: true — always confirm with the user firstSee references/common-devices.md for register maps and usage of popular sensors:
AHT20, BME280, SSD1306 OLED, MPU6050 IMU, DS3231 RTC, INA219 power monitor, PCA9685 PWM, and more.
| Problem | Solution |
|---|---|
| No I2C buses found | modprobe i2c-dev and check device tree |
| Permission denied | Run as root or add user to i2c group |
| No devices on scan | Check wiring, pull-up resistors (4.7k typical), and pinmux |
| Bus number changed | I2C adapter numbers can shift between boots; use i2c detect to find current assignment |
| WiFi stopped working | I2C-1/SPI-2 share pins with WiFi SDIO; can't use both simultaneously |
devmem not found | Download separately or use busybox devmem |
| SPI transfer returns all zeros | Check MISO wiring and device power |
| SPI transfer returns all 0xFF | Device not responding; check CS pin and clock polarity (mode) |
