Tenet70-Tools

A firmware flashing tool for the Metakey Tenet 70 and other keyboards that use the Hexcore IAP protocol. The compiled binary is called hexcore_flash.

This is a fork of AnnePro2-Tools, originally written for the Anne Pro 2. It keeps working with the Anne Pro 2 and adds a tenet-70 device profile, device auto-detection, and a read-only --probe mode.

Supported devices:

Profile	VID	PID	MCU	Notes
anne-pro-2-c15	0x04D9	0x8008	HT32F52342	64K flash
anne-pro-2-c18	0x04D9	0x8009	HT32F52352	128K flash
tenet-70	0x3311	0xF005	HT32F52352	wired-only, OLED+RGB

Put the keyboard into IAP mode by holding esc while plugging it in before running this tool.

To build:

cargo build --release

To flash a file called a.bin:

./target/release/hexcore_flash a.bin               # auto-detect device
./target/release/hexcore_flash --device tenet-70 a.bin
./target/release/hexcore_flash -d anne-pro-2-c18 -t main a.bin

To verify the device is reachable without writing anything (read-only IAP probe):

./target/release/hexcore_flash --probe              # auto-detect
./target/release/hexcore_flash --device tenet-70 --probe

By default the flasher auto-detects a connected supported device and flashes the binary starting at 0x4000 (the standard app slot above the IAP bootloader on every known device).

Nix flake

For development:

• nix-shell starts a Rust development shell
• nix shell starts a shell for building and testing hexcore_flash

With the flake you can also build or run it directly:

nix run github:connorgallopo/Tenet70-Tools -- --help
nix build github:connorgallopo/Tenet70-Tools#hexcore-flash
