Re: [lwip-users] new at lwip, running test on windows using PPP

[zulu4711]

Thanks for input Simon, really appreciated!

I can confirm that the PPP_INPROC_IRQ_SAFE is set to 1.


Basically I have just taken the ppp sample from contrib and added my own
"worker thread" that calls the socket functions, maybe I have done something
wrong with that !?

My init/main looks like this:

/* This is somewhat different to other ports: we have a main loop here:
 * a dedicated task that waits for packets to arrive. This would normally be
 * done from interrupt context with embedded hardware, but we don't get an
 * interrupt in windows for that :-) */
static void main_loop(void) {
  err_t err;
  sys_sem_t init_sem;

  int count;
  u8_t rxbuf[1024];
  volatile int callClosePpp = 0;

  /* initialize lwIP stack, network interfaces and applications */
  err = sys_sem_new(&init_sem, 0);
  LWIP_ASSERT("failed to create init_sem", err == ERR_OK);
  tcpip_init(test_init, &init_sem);
  /* we have to wait for initialization to finish before
   * calling update_adapter()! */
  sys_sem_wait(&init_sem);
  sys_sem_free(&init_sem);


//      while (netif_is_link_up(&ppp_netif)==0)       sys_msleep(1000);


  //_beginthread(thWorkerUDP,0,NULL);
  //sleepy(1000);
  //_beginthread(thWorkerUDP,0,NULL);
//  sleepy(1000);
  
  

  // CHG Test 25-11 2017
   //_beginthread(thWorkerSocket,0,NULL);
//
   sys_thread_new("thWorkerSocket", thWorkerSocket, NULL,
DEFAULT_THREAD_STACKSIZE, DEFAULT_THREAD_PRIO);
