    Debugger hits an exception in wiced_init()

    NaFi_2915566

      Using a CYW943907AEVAL1F and Wiced Studio, I can download and start the debugger using the instructions in Re: wiced Debug , but when I try to debgu I haev problems:

      • the first line of my appication_start() is wiced_init().  If I set a breakpoint on that lien I can get there
      • If I try to step over wiced_init(), it never returns.  Instead I end up in data_abort_handler()
      • The code works fine if I run it without debug.

      Any idea what may be causing this?
