If you are starting a new MCU or SoC thread, post enough context that someone else can reproduce your failure mode instead of guessing blindly.

A good first post usually includes the exact device, board or custom hardware revision, toolchain version, debugger, clock source, power rails, and whether you are failing at reset, flash, boot, or runtime.

• Part number and board revision
• Toolchain, IDE, compiler, and probe
• Clock configuration and boot mode straps
• Power rail measurements at startup
• What works, what fails, and what changed last
• Relevant schematic snippet or register dump

If you already checked reset, clocks, flash option bytes, and SWD connectivity, say so. That saves everyone time.
