Do not connect the 3.3V or 5V power pin from your USB-to-TTL adapter to the STB if you are plugging the STB into its own wall adapter. Powering the board from two distinct sources simultaneously can damage the SoC or your PC’s USB port. 2. Match the Terminal Communication Settings
: If you are using a Serial-to-USB adapter (TTL), ensure TX on the adapter goes to RX on the board, and RX goes to TX . 2. Force the Device into MaskROM Mode
When a set-top box powers on, the BootROM executes the earliest stage of code. It checks the onboard storage (eMMC, NAND, or SPI flash) for the secondary bootloader (like U-Boot). If it cannot find or read that storage, it falls back to a recovery or programming mode, exposing a serial interface to accept code externally. The "Wait for Get" loop happens due to specific triggers:
To help narrow down the fix for your specific hardware, please share (e.g., Amlogic, HiSilicon, Rockchip) and the exact software tool you are using to flash it. Share public link
The software is looking at the wrong virtual serial port, or the speed (baud rate) is mismatched. Do not connect the 3
Are you experiencing a frustrating bootrom error on your device, specifically with the message "wait for get please check stb uart receive google"? This error can be a major setback, preventing you from using your device or accessing critical data. In this article, we'll dive into the world of bootrom errors, explore the possible causes, and provide a step-by-step guide on how to troubleshoot and fix the issue.
When a serial flashing interface times out, the failure can typically be traced to one of four technical failure points: Technical Failure Mode

If standard methods fail, consider these alternatives: Match the Terminal Communication Settings : If you
: Ensure the RX pin on the adapter goes to the TX pin on the device, and vice versa. STMicroelectronics Community Are you attempting to a specific brand of Android TV box or set-top box? Bootrom Error Wait For Get Please Check Stb Uart Receive
: On some unbrickable devices, you must manually short the eMMC "CLK" or "Data" pins to GND momentarily during power-up to prevent the device from loading corrupted internal firmware and force it into MaskROM mode. 3. Update Drivers and Software
: Look for a tiny "Reset" button (often hidden inside the AV port). The Sequence
: If the error persists, disconnect the cable from the STB and bridge the TX and RX pins on the cable itself. Use a terminal program like Tera Term to see if typed characters are echoed back; if not, your cable or driver is faulty. It checks the onboard storage (eMMC, NAND, or
: Swapping the TX and RX pins. The TX (Transmit) of your adapter must connect to the RX (Receive) of the STB, and vice versa.

The terminal spat out a new code: GXL:BL40:9ac508... Then: 0x81 (A code indicating the CPU is ready to receive data over USB).
. It essentially means the software is sending a command but isn't receiving the expected response from the device's UART (Universal Asynchronous Receiver-Transmitter). Core Meaning The flashing tool (such as Amlogic Burn Card Maker Rockchip Batch Tool
The Transmit (Tx) and Receive (Rx) wires on your USB-to-TTL adapter are either loose, broken, or crossed incorrectly.
Many boards use logic. If your USB-to-UART adapter is set to 5V, it may cause communication errors or damage the chip. Potential Causes
