A classic mistake where the transmitter is connected to the transmitter instead of the receiver.
The software is "talking" at a different speed than the hardware is "listening" (common speeds are 115200 or 921600). Bootrom Error Wait For Get Please Check Stb Uart Receive
Essentially, the BootROM—the permanent code on the device's chip—is waiting for data (firmware) to arrive via the UART (Universal Asynchronous Receiver-Transmitter) serial port, but it isn't receiving a response. Common Causes of the Error A classic mistake where the transmitter is connected
The most frequent culprit is a physical wiring error. Check the following: Bootrom Error Wait For Get Please Check Stb Uart Receive
This allows the software to catch the initial "Handshake" signal as the BootROM initializes. 5. Using the Short-Circuit Method (Mask ROM Mode)
If you provide these details, I can give you the specific and pinout diagram for your device.
