This looks like a request to for a set-top box (STB), embedded Linux system, or bootloader environment, where a typical UART error message appears: Bootrom Error Wait For Get Please Check Stb Uart Receive This message usually means the BootROM tried to download a boot image over UART (e.g., via xmodem, ymodem, or a proprietary protocol) but didn’t receive expected data from the host PC. def detect_error(port, baudrate=115200): ser = serial
