[En-Nut-Discussion] Problem in multi thread

[Ole Reinhardt]

Hello,

>          I am using two threads in my program. In both the threads accesing
> same port. due to this program crash. how to avoid thiz.

Could you please explain a little more in detail what your program shall
do and how you have implemented it? What do you mean with "crash"? A
Real lock up / exception? Or does the output on the port (UART?) is
corrupted?

Futher informations would be needed:

- Which board?
- Which Nut/OS version?
- Which port?

Perhaps you could post your code or part of it here?

As a first assumption you might have a stack or buffer overflow here.
These are the most common reasons for Nut/OS crashes.

If you just get corrupted (mixed) output on your port you can avoid this
by using a mutex.

Best regards,

Ole Reinhardt
