- Embedded teams shipping firmware frequently
- Worth noticing
- An illustrative trace pinpoints an I²C read at address 0x48 that never ACKs, with the first divergence at 1,214 ms.
Field notes
The proposed workflow starts with the same ELF build intended for the chip, then uses a scenario file to script inputs such as a sensor going silent. The example expects a UART warning and a 2 Hz blink on PA5, while its illustrative trace reports an unacknowledged I²C read and a stalled clock line. The site says runs can start from CI, an API, or an AI agent, but labels the product early beta.
