ARM Exception


#1

Hi All,

I am getting “ARM Exception 1 7074a3b 9000000” in a trace of an application that uses the TCP/IP library through the standard IPConnect projcet. Any ideas where I could get more information on this?

regards,
Mike

Hi MikeBean,
To my experience, this problem usually occurs in the following cases:

  1. When the Open-AT application overwrites the allocated buffer space.
  2. When the stack size is less.
  3. When illegally trying to access a particular portion of memory.

More information can be searched in ARM documentation.
Have you tried to compile with GCC compiler.

I have also seen RTK exceptions that occur during such cases.

Hi Open_AT Fan,

Thanks for the Response. It was memory access violations caused by some overzealous memory disposal.

Kind regards,
Mike
