wip_netInit() problem

I have problem with wip_netInit() function. I use Q2501B (ver. 657e09gg).
If I call wip_netInit() I have “Except RTK … 190 1a26”.
If I call wip_netInitOpts(WIP_NET_OPT_SOCK_MAX,1,WIP_NET_OPT_BUF_MAX,4,WIP_NET_OPT_END) I have “Arm Exception 1 7fffb78 9000000”.
How correctly to initialize a stack?

The problem is solved. It was necessary to increase the size of a stack wm_apmCustomStack (Default:256).
