Firmware development for the Guition JC-ESP32P4-M3-DEV board (JC-ESP32P4-M3 module — ESP32-P4NRW32 with 32 MB in-package PSRAM, 16 MB flash, and an ESP32-C6 radio co-processor on SDIO) — its MIPI-DSI panel and MIPI-CSI camera connectors, IP101 Ethernet, ES8311 codec with speaker amplifier and microphone, microSD on SDMMC, RS485, three USB-C sockets, the 26-pin JP1 header, and the PlatformIO + ESP-IDF (pioarduino) setup around them. Use when working on this board or any ESP32-P4 devkit: project…
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
# Guition JC-ESP32P4-M3-DEV An ESP32-P4 carrier with a MIPI display connector, a MIPI camera connector, Ethernet, audio, a card slot, RS485, a battery charger and **three USB-C sockets** — and a radio that is a second chip you talk to over SDIO. Three things shape almost every task on this board. First, **the P4 has no radio**: `esp_wifi` is not the API, `esp_wifi_remote` over `esp_hosted` is, and the ESP32-C6 inside the module needs its own firmware. Second, **the silicon comes in two mutually incompatible revisions** and ESP-IDF defaults to the wrong one for the boards being sold — the symptom is a bootloader that dies with `Illegal instruction`, which reads like corrupt flash. Third, **there is no user LED**: the only thing that lights is the power indicator, so a board that "does nothing" is usually a board that is running fine with its console on the wrong socket. - `reference/board-hardware.md` — the board: the module pin list transcribed from the schematic, every P4 GPIO and what this board did with it, the JP1 header with its four trap positions, power tree, Ethernet, I2C, audio, storage, the silicon-revision table, …

How to install
mdr add alexex1993/mcu-skills/esp32p4-jc-m3-dev@sha256:1c8d287c3fcb83e3The 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.
