你用的是什么程序，你在KDS中新建一个工程，添加最简单的打印测试代码下载跑试试，看看是否复位。
关于LOCKUP的解释：
The LOCKUP gives immediate indication of seriously errant kernel software. This is the
result of the core being locked because of an unrecoverable exception following the
activation of the processor’s built in system state protection hardware.
应该还是和你软件程序有关。
你先做个最简单的测试程序试试。
