Re: [lwip-users] Fail to get netconn lwip1.4.1+FreeRTOS+TM4C1294

Hi Richard,

Well even though I changed the codes that you mentioned like
  vQueueDelete(sem->queue);
  sem->queue = 0;

It doesn't make any differences.

When semaphore is created it stores in global sems[MAX] and keep increasing array without freeing the used semaphore. So it reaches to the max assigned in the array and stop working.

I am trying to add configASSERT() in my codes but it gives unknown errors that seem to do with asmbly file(portasm.asm)

I will try but I am not sure how adding configASSERT() helps me that much.

Thanks,

Jin

I have just replied to the same on the FreeRTOS forum where the suggestion of referring to our reference integration was politely declined.

For others on this list:  There is a memory leak in the poster's code because the pointer needed to free the semaphore is overwritten with 0 without the semaphore having first been freed, and then there is an attempt to free the now NULL pointer.  The FreeRTOS FAQ suggests defining configASSERT() when having stability issues - two asserts would have been triggered in this case.

Richard.

I tried before without sem->queue=0, but all same.

I meant calling 'vQueueDelete()' before setting queue=0.

I reported both TI and FreeRTOS, but TI have not responded yet and
FreeRTOS replied "They have a own network stack", so they are not sure
about lwip.

That's strange. Richard from freertos.org used to be very acive here.
Although I admit he hasn't been lately, so things might have changed
there...
