If the data is not detected, the process hangs, and the "Check Stb Uart Receive" message is displayed, signaling a break in the link between the PC and the decoder. Primary Causes of Communication Failure
Would you like help with a specific device or chipset (e.g., Hisilicon, Amlogic, Broadcom, MStar)?
Some early BootROMs (e.g., Hi3716C v1.0) have a bug where they ignore UART after the first retry. You can verify by:
Your computer is not communicating with the box. The "Bootrom" is the lowest level of software on the chip, and it is waiting for a signal from your PC that it never receives. This is almost always a hardware or driver issue , not a problem with the firmware file itself.
Some devices require an external 24MHz crystal. If it is faulty, the UART baud rate (typically 115200) will drift, causing framing errors that trigger the "Uart Receive" check.

This is the key. For Hisilicon Hi37xx:
