The error is a critical failure message typically seen when trying to flash or recover a set-top box (STB) using an external serial connection. It indicates that the device's internal BootROM is waiting for a command ("get") from the host computer but is failing to establish a stable handshake. Root Causes of the Failure
Set the to exactly 115200 (the standard for most Amlogic, Rockchip, and Allwinner STBs). Some older boards may use 9600 or 57600 . Set Data Bits to 8 . Set Parity to None . Set Stop Bits to 1 . Set Flow Control to None . Step 3: Master the Power-On Sequence
Connect on your USB-to-TTL adapter to RX on the STB board.
: If your computer's COM port isn't properly configured or the USB-to-UART driver is malfunctioning, the "GET" signal never leaves the PC. How to Fix It bootrom error wait for get please check stb uart receive hot
The error message "bootrom error wait for get please check stb uart receive hot"
Confirm the TX pin of the adapter goes to the RX pin of the STB, and vice versa. Ensure a common (Ground) is connected. 3 Timing the Boot
Use a metal needle or tweezers to gently short these two pins together while plugging in the power. The error is a critical failure message typically
Some high-speed flashing utilities automatically switch to or 1500000 .
: The STB must usually be powered on after the "Start" button in the upgrade tool is pressed to trigger the bootloader mode. Troubleshooting Steps
: Often "Even" or "None" depending on the specific chip. Some older boards may use 9600 or 57600
:
: The tool (like GXDownloader) is waiting for a "handshake" that happens the moment the STB is powered on. Baud Rate/Voltage Error
The problem is occurring at the lowest level of the device's hardware initialization, before the main operating system (Android, Linux, etc.) loads.
This suggests that the BootROM has entered a or recovery mode via UART. The CPU is waiting ( wait ) to "get" a specific handshake command or bootloader image sent from an external host (i.e., your PC) over the UART interface. It is actively listening for a signal like 0xCC or a proprietary handshake sequence, but it isn't receiving it.
