Embassy boot and dfu flashing by Schievel1 · Pull Request #877 · HaoboGu/rmk

Schievel1 · 2026-06-08T22:24:51Z

This PR adds DFU (Device Firmware Upgrade) support via embassy-boot for RP2040-based keyboards. Once set up, firmware updates can be done over USB with dfu-util — no need to press BOOTSEL or use a debug probe.

What's implemented

rmk crate — new dfu_rp feature gate:

dfu.rs: init_flash() initializes the blocking flash with configurable partition offsets and returns a storage partition for RMK's keymap storage
set_led() / mark_booted() — optional DFU activity LED and boot-success signaling to prevent bootloader rollback
register_dfu_interface() — registers a USB DFU class (embassy-usb-dfu) with a handler that blinks the LED during transfers
DfuLock (behind dfu_lock feature) — physical key unlock for DFU: pressing the configured matrix keys unlocks DFU for 10 s, with Morse "DFU" LED blinking
Automatic DFU interface registration in UsbTransport::new() when the manager is initialized

rmk-config crate — new [dfu] TOML section:

flash_size, page_size — auto-calculate partition addresses using the bootymcbootface formula (state at 0x6000, active at 0x7000, DFU slot follows) (bootymcbootface (https://codeberg.org/Schievel/bootymcbootface/) is the matching bootloader for this, but people could roll their own and use whatever partitioning suits them)
led — optional GPIO pin for DFU activity
unlock_keys — matrix positions for dfu_lock
Manual override of state_offset, state_size, dfu_offset, dfu_size for custom layouts

Examples:

examples/use_rust/rp2040_embassy_boot/ — full Rust-API example
Example configs updated for use_config path

Documentation:

New user_guide/flash_firmware/use_embassy_boot.mdx with setup guide (bootymcbootface, compilation, step-by-step flashing, DFU usage, dfu_lock, LED behavior)
RP2040 + embassy-boot section in configuration/chip_config.mdx with partition table and TOML/Rust tabs

Feature flags

dfu — base DFU support (USB DFU interface)
dfu_rp — RP2040-specific DFU with embassy-boot (implies dfu + rp2040)
dfu_lock — physical key unlock for DFU (implies dfu_rp + host_security)

Usage flow

Flash bootymcbootface (once, via UF2 or probe-rs)
Compile RMK with dfu_rp feature and matching flash size
Flash RMK firmware (via UF2 or probe-rs)
All future updates: cargo make bin && dfu-util -D firmware.bin

Perspective

Since embassy-boot is agnostic towards how the updated firmware gets into the DFU partition, this PR lays the foundation for future features like flashing via bluetooth or flashing the peripheral from the central using the serial connection between them.
