Issue Description
Usually we will meet a problem, we think the 90xx is faulty, though upgrade or reset factory, we can`t solve it, then we will go RMA, how should we know the physical is really faulty or not?
Solution
【WAYS】
The startup traces.
【METHOD】
1. Connect the serial cable between laptop and COM1 in the terminal.
2. We suggest use CRT to connect the COM1 and select the traces.
(1) Save the file first(because the traces is a lot, it will be earsed by the later one)

(2) Click the connection button to connect.
(3) Choose the serial protocol and configure relative settings
serial port
speed:9600
(4) Click the connect. Restart the termail and it will print lots of traces. Save it and send it back to R&D.
because when the facility startup, it will load every units, if can`t be loaded, it will be printed in the traces.
