: Always ensure there is a common ground connection between the STB and the UART adapter.
This error typically appears in or embedded device firmware flashing tools (e.g., Hitool, Rld, or proprietary ISP software). It indicates that the BootROM on the target device is waiting for a specific handshake or command ( get command) from the host PC via UART , but the host is not receiving the expected response from the device.
