hi,
I ported lwip + ucosII to STR710FZ2(ARM7TDMI)，ucosII
works fine, but Lwip has a problem I can not figure out.
When a pocket 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?
