昨天晚上遇到

###################### User Menu for OK6410#####################
[1] Format the nand flash

[2] Burn image from SD card

[3] Burn image from USB

[4] Reboot the u-boot

[5] Exit to command line

—————————–Select———————————

Enter your Selection:1

NAND scrub: device 0 whole chip

Warning: scrub option will erase all factory set bad blocks!
There is no reliable way to recover them.

Use this command only for testing purposes if you

are sure of what you are doing!

Really scrub this NAND flash? <y/N>
scrub aborted

弄到晚上1点，

结果解决方法：按y/N还要加Enter键

台式机的串口直接与开发板的串口相连SecureCRT无法输入问题。

结果解决方法：由于没有加CH340串口线，加上就可以输入了。
