Flash utility and firmware binaries for EchoCard MCU 525
It solves the hassle of flashing EchoCard MCU 525 by providing pre‑built firmware binaries and shell scripts that automate UART flashing and BLE reset. The scripts detect the active serial port, invoke the sftool utility, and include safety checks for erasing or resetting slots. Designed for hardware developers and integrators who need quick firmware updates without compiling the full source. Compared to building from source, this package offers a streamlined, documented workflow for reliable board programming.
