Firmware archive identified only as CA10SUG with a 2mb tag, most likely a 2 MB image variant, in a 1.29 MB ZIP. No device model, brand or board number appears, so identify the target hardware carefully before use. The size tag matters, because an image must match the flash chip capacity exactly or it will not fit and the programmer will refuse or misplace data. Read the existing chip first and keep that backup. Then compare the chip markings with the 2 MB size before writing with an SPI programmer.
