Thank you.

I have tried dual core running simultaneously recently.

However,I found that when running a uclinux system and a program generated on the basic of reference design "helloworld_small", it runs perfectly.

When running a uclinux system and a program generated on the basic of reference design "helloworld", either of the process will stop.

There&#39;s only a difference lies in the syslib between "helloworld_small" and "helloworld", I don&#39;t know why "helloworld" leading to the unknown interruption.
