Re: [lwip-users] FreeRTOS :: LWIP xInsideISR == (portBASE_TYPE)

Hi，
    Maybe you call sys_arch_mbox_fetch(...)(by direct or indirect) inside your 
Interrupt Service Routine with a non-zero timeout.
    If you want to call sys_arch_mbox_fetch from your ISR, you can only specify 
a zero-timeout.

Subject: [lwip-users] FreeRTOS :: LWIP xInsideISR == (portBASE_TYPE)
Hello,

i am using lwip 1.4.1 and FreeRTOS 7.4. in sys_arch.c i am getting this assert:

configASSERT(xInsideISR == (portBASE_TYPE) 0); (full code below). So im asking 
why is that happened ?

I am rookie at these staff so be patient :)

If anyone can help :)

Full code:

u32_t sys_arch_mbox_fetch(sys_mbox_t *pxMailBox, void **ppvBuffer, u32_t 
ulTimeOut)
{
void *pvDummy;
portTickType xStartTime, xEndTime, xElapsed;
unsigned long ulReturn;
xStartTime = xTaskGetTickCount();
if(NULL == ppvBuffer) {
ppvBuffer = &pvDummy;
}
if(ulTimeOut != 0UL) {
configASSERT(xInsideISR == (portBASE_TYPE) 0);
if(pdTRUE == xQueueReceive(*pxMailBox, &(*ppvBuffer), ulTimeOut / 
portTICK_RATE_MS)) {
xEndTime = xTaskGetTickCount();
xElapsed = (xEndTime - xStartTime) * portTICK_RATE_MS;
ulReturn = xElapsed;
} else {
/* Timed out. */
*ppvBuffer = NULL;
ulReturn = SYS_ARCH_TIMEOUT;
}
} else {
while(pdTRUE != xQueueReceive(*pxMailBox, &(*ppvBuffer), portMAX_DELAY));
xEndTime = xTaskGetTickCount();
xElapsed = (xEndTime - xStartTime) * portTICK_RATE_MS;
if(xElapsed == 0UL) {
xElapsed = 1UL;
}
ulReturn = xElapsed;
}
return ulReturn;
}
