This error indicates a communication breakdown between your Set-Top Box (STB) and the computer while attempting a firmware upgrade or "revival" process
. It usually means the STB is waiting for data, but the computer’s command isn't reaching it. Lemmy Morgan Likely Causes & Troubleshooting Cable Connection : Ensure you are using a cross-line RS232 cable (Null Modem) rather than a straight-through cable. Driver Issues
: Verify the RS232-to-USB driver is correctly installed in Windows Device Manager. Incorrect COM Port
: Check which COM port your computer assigned to the cable (e.g., COM3) and match it exactly in the upgrade tool. Baud Rate Mismatch : The standard speed is often , but some devices require specific rates like Timing of Power-On
: After clicking "Start" in your upgrade tool, you must power on or manually restart the STB within a few seconds for the bootloader to engage. Lemmy Morgan Recommended Recovery Steps Check Hardware : Re-seat the cable and ensure the (ground) connection is solid. Verify COM Settings This error indicates a communication breakdown between your
: In your tool (like "GXDownloader_boot.exe"), double-check that the "Chip Type" and "Boot File" match your specific model. Try a Loopback Test : Connect the TX and RX pins
of your cable together and type in a terminal (like PuTTY). If you see the letters you type, the cable is working; if not, the cable or driver is faulty. STMicroelectronics Community pinout diagrams for your STB's UART port to verify your wiring?
This error typically occurs when trying to flash firmware or "revive" a Set-Top Box (STB) or Android TV box (often those with Amlogic or Rockchip processors) using a PC and a serial connection (RS232 or USB-to-TTL).
The message indicates that the computer's flashing tool is waiting for a response ("GET" command) from the device’s BootROM, but the device is either not sending it or the computer is not receiving it. Core Reasons for the Error Why Does This Error Happen
I understand you’re looking for a formal technical paper addressing a “bootrom error” with the message:
"bootrom error wait for get please check stb uart receive google"
However, this string appears to be a raw console log from a set-top box (STB) or embedded device, not a standard error message from Google products. To help you develop a proper paper, I’ll need to make some assumptions and frame it as a technical troubleshooting and analysis document.
Below is a structured technical paper based on the likely scenario: or debug a set-top box (STB)
Understanding the cause is 90% of the fix. Here is why you see this message:
The “bootrom error wait for get please check stb uart receive google” is a low-level BootROM handshake timeout. It can be resolved by restoring UART communication or using alternative flash tools. Prevention includes avoiding interrupted bootloader writes and ensuring proper UART grounding.
This error typically appears when trying to flash firmware, unbrick, or debug a set-top box (STB), Android TV box, or embedded device that uses an Amlogic, Rockchip, or similar system-on-chip (SoC). The message is generated by low-level BootROM code when the device is in USB burning mode or Mask ROM mode.
