Bootrom Error Wait For Get Please Check Stb Uart Receive Hot May 2026
Check Voltage Levels
Confirm BootROM Baud Rate
Correct Host Software Procedure
Check for “Hot” UART Receive
Test with Simple Loopback
The most common cause. The BootROM checked the boot device (eMMC, NAND) and found:
Many BootROMs (especially on Hisilicon Hi37xx and Amlogic S905 series) support XMODEM transfer of a temporary bootloader. bootrom error wait for get please check stb uart receive hot
In cold boot (UART connected before power), RX is typically high due to pull-up. In hot attach:
Thus the message advises: Check if your UART cable is being connected/disconnected while the STB is powered (hot). Check Voltage Levels
| Message Fragment | Meaning |
|----------------|---------|
| bootrom error | The BootROM (mask ROM) encountered a fatal condition during the early boot or firmware download phase. |
| wait for get | The bootloader is stuck waiting for a specific handshake or command (e.g., “get” command from host via UART). |
| please check stb uart receive hot | Suggests checking the STB’s UART reception – “hot” might mean “active” or “live” (possibly a translation issue). Indicates that UART RX is not receiving expected data. |
Likely Root Cause:
The BootROM is in download mode, expecting a bootstream or firmware image via UART, but the host PC is not sending the required data, or the UART connection is faulty. Confirm BootROM Baud Rate
