关于栈被自己重置和数据丢失

嗨,对话框中,

我现在使用堆栈来做广告，我已经设置的时间段是2.5s通过使用计时器。我在我的程序中使用的“current_role”用于控制程序“app_task.c”和“app.c”中的角色切换。但是当它运行25次的角色切换时，它将重置整个程序，并丢失了所有的东西之前放入了RAM之前，请您帮助您解决这个问题吗？

下面是app_task.c程序的一部分:
Extern volatile uint8_t current_role;

Int app_switch_role(ke_msg_id_t msgid, void *param, ke_task_id_t dest_id, ke_task_id_t src_id)
｛
app_gapm_reset_op ();

返回(KE_MSG_CONSUMED);
｝
