  • STRTT-style RTT control-block scanning using SEGGER_RTT_CB and buffer descriptors
  • Use cases include diagnosing RTT throughput and data integrity during STM32 debugging sessions

Quick Start

Run the bootstrap to initialize the STRTT RTT polling workflow.

Frequently Asked Questions about bfd-strtt-rtt

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I capture SEGGER RTT data using ST-Link memory polling?▼

ST-Link memory polling captures SEGGER RTT data by scanning for the SEGGER_RTT_CB control block and extracting buffer descriptors. This enables reliable host-side RTT data consumption during STM32 debugging.

What is STRTT-style RTT control-block scanning and when do I need it?▼

STRTT-style RTT control-block scanning identifies the SEGGER_RTT_CB structure and its descriptor rings in target memory. You need it when diagnosing RTT throughput and data integrity on STM32 targets.

How do I handle RdOff correctly for host-side RTT ring-buffer polling?▼

Correct RdOff handling during RTT ring-buffer polling ensures the host-side consumer reads valid data from the buffer. Proper offset management prevents data loss and maintains reliable RTT extraction.

Can I use this for diagnosing RTT throughput during STM32 debugging sessions?▼

Yes, you can diagnose RTT throughput and data integrity during STM32 debugging sessions. The workflow applies memory-polling RTT access to capture and evaluate SEGGER RTT traffic reliably.

Does ST-Link support reliable memory-polling RTT access without SEGGER tools?▼

ST-Link supports reliable memory-polling RTT access by directly reading target memory for the SEGGER_RTT_CB block. This bypasses dedicated SEGGER hardware to extract RTT data via standard ST-Link interfaces.
