  I ported lwip + ucosII to STR710FZ2(ARM7TDMI),ucosII works fine, but Lwip has a problem I can not figure out.
  When packets received, The NIC interrupt call tcpip_input() to creat a message. then tcpip_input() need to call memp_malloc() to create a new message, memp_malloc() need to call OSSemPend() to wait for a semaphore.
  The problem is OSSemPend() can not be called in a interrupt. Is there anyone has the same question? How can I get through it?
