Program Not Working/Flashing On Tang Nano 9K

I'm Try To Run CFU-Playground in Tang Nano 9K, But It's Stucked.
The Command:
```
make load TTY=/dev/ttyUSB1 TARGET=sipeed_tang_nano_9k
```
The Output:
```

```
The Program Was Stucked At Last Output.
I'm Also Try To Tun Same Command With Another Com Port(`/dev/ttyUSB0`), But Result is same:
```
make load TTY=/dev/ttyUSB0 TARGET=sipeed_tang_nano_9k
```
