OBS: The network that ESP8266 STATION MODE is going to connect must exist to reproduce the error.
OBS2: This example works fine using the old version of libmain, libpp and lib80211.
Another question, can you folks please improve the port.c file from RTOS_SDK/third_party/freertos, that file is really a mess, there are a lot of commented code inside it... Also please update the ShowCritical() function to use os_printf instead of ets_printf, and print the entire stack, so we can see where the problem is hapenning...
Code:
void ShowCritical(void)
{
ets_printf("ShowCritical:%d\n",uxCriticalNesting);
ets_delay_us(50000);
}
