Firmware development for the <VENDOR> <BOARD NAME> (<MCU PART NUMBER>) — its <peripheral>, <peripheral>, <peripheral>, and the <SDK/HAL> + <build system> setup around them. Use when working on this board or any <compatible siblings>: project setup, <config file>, clock configuration, pin mapping, peripheral bring-up, <the board's headline concern>, flashing, or debugging why something on the board does not work.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# <Vendor> <Board> (<MCU>) <One paragraph: what this board is, and what the reference files hold. Say explicitly that the detail lives in the reference files and should be read rather than guessed at.> - `reference/board-hardware.md` — <what it answers> - `reference/recipes.md` — <what it answers> - `template/` — a complete working project that builds and flashes, plus a scaffolding script. ## Orientation | | | |---|---| | MCU | <part number, core, flash, RAM, package> | | Clocks | <crystals populated, and the clock tree that is known to work> | | Display | <controller, resolution, bus, pins> | | LED / button | <pin and **polarity** for each> | | Storage | <internal / external flash, SD, PSRAM, with addresses> | | USB | <peripheral, pins, bootloader behaviour> | | Debug | <SWD/JTAG/UART header and pins> | <Delete rows that don't apply; add rows the board needs.> ## Rules that prevent the expensive mistakes <10–15 numbered rules from your bring-up log. Each is imperative and carries its consequence. Template for one entry:> 1. **`<the setting, in code form>`** — <why the board needs it>. Without it, <the symptom, which should not obviously point back at this setting>. …

How to install
mdr add alexex1993/mcu-skills/REPLACE-with-skill-name@sha256:504ee8677eae82abThe line at the top of this page pins the label git:20261030.816967f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
