WEB FLASHER

Flash official HaleHound™ firmware straight from your browser. Nothing to install.

Select your board

Web Serial is not supported in this browser. Flashing is only allowed over HTTPS.

When you click Connect & Flash, a port popup appears. It's filtered to real boards, so you'll usually see just one entry - named USB Serial, CH340, wchusbserial, or CP210x. That's your HaleHound. Pick it and hit Connect.

How to flash

Unplug other USB gadgets, then plug in only your HaleHound with a data USB cable (not charge-only).
Pick your exact board from the menu above.
Click Connect & Flash, pick the one port in the popup, and confirm.
Leave it connected until it reports done, then unplug and replug to reboot.

Port popup empty / board missing? Install the USB driver - CH340 (most boards) or CP210x - then replug and retry. Wrong board picked? It may go to a black screen - just re-flash the right one, nothing is harmed.
