怎样退出LLS模式--How to exit LLS mode

[jianjiazeng]

测试LLS模式的时候让K21板启动后直接进入LLS模式，现在Jlink不能下载调试了。

按reset键后也是直接进入LLS模式.请问我该怎么办???\

帮帮我，很急！！

Translation:

It can not download and debug when K21 board enters in LLS mode after booting up. It enters LLS mode as well even after pressing reset key. Please help. it is urgent.

Hi JianJia,

You could use J-Link do mass erase with J-Link Commander tool, such as "unlock Kinetis".

After that, you need to modify your test code, you could let serial termial input some charaters to let board enter into LLS low power mode.

Wish it heps.
