串口打印CCC之后，tera term 在xmodem下1k传输u-boot.min.uart，按下reset键后程序没有下进去，而且卡在下面的地方
Chi Xiaoyan,
串口设置是否正确？
* Baud rate: 115,200
* Data bits: 8
* Parity: None
* Stop bits: 1
* Flow control: None
* Transmit delay: 0 msec/char, 100 msec/line
应该没错吧，已经能正常打印CCC了，板子是公司做的，reset有什么要求吗？
reset的低电平保持有时间要求。
你可以把复位，换成断电+上电看看？
