Errata Lens: an ESP32 agent that knows when the datasheet is wrong

Описание и применение

Errata Lens — инструмент, который проверяет, применим ли конкретный баг ESP32 к выбранной ревизии чипа, используя базу знаний и GROQ‑запросы.

Задача

ESP32 datasheet is identical across silicon revisions, but errata differ; engineers cannot quickly determine if a bug applies to their exact revision, leading to wasted time and potential failures.

Результат

The agent accurately reports revision‑specific errata, such as identifying that WDT‑3.15 only appears on v3.x and that GPIO‑3.11 is a known glitch on v1.1. It provides counts of fixed and new errata when upgrading revisions, enabling informed decisions.

Рабочий процесс

• 1. User selects silicon revision in the web app.
• 2. User asks a question (e.g., "Is GPIO36 safe with Wi‑Fi on?").
• 3. Agent identifies revision via local tool or user input.
• 4. Agent queries Knowledge Base for datasheet statements.
• 5. Agent queries GROQ database for errata affecting that revision.
• 6. Agent compiles answer with datasheet, errata overrides, and revision context.
• 7. User reviews answer and takes action.

Доказательства

Errata Lens answers ESP32 questions the way a careful senior engineer does: it checks whether the chip's errata overrides the datasheet, for the exact silicon revision on your board.

Источник

The build distilled 118 documents into 23 entries, tagging the errata topics [core] because the Knowledge Base's purpose names them.

Источник

It got those counts (25 on v1.1, 23 on v3.1) from GROQ joins, then read the Knowledge Base for the WDT-3.15 workaround: a level 4/5 timer interrupt on each core.
