Re: [lwip-users] LWIP_ASSERT on pbuf_free function

I'm not well versed in sockets here, but since you are using sockets, there shouldn't be application-related pbuf free issues if threading rules are respected. Somewhere in your vendor provided code, someone did not play by the rules. You have an OS, you have a port, you have a driver, you have man

[lwip-users] LWIP_ASSERT on pbuf_free function

Hi everyone, I'm using MCUXpresso 10.2.1 and a custom board based on MK65F2M0 chip. I have a problem on using LwIP: it sometimes crash generating an assert, because of some invalid parameter. The workflow is: * The board is configured with a main connection using a GPRS modem and an o

Hi, could you provide some test case? I mean the code you are using (if it is possible) to be able to re-create the assertion failure. Best Martin On Thu, Mar 6, 2014 at 10:35 AM, Dmitriy Zabotlin wrote: > Hi, > > > I have a problem with lwip in my embedded application, I'm using FreeRTOS > 7.6

[lwip-users] LWIP_ASSERT conn->current_msg != NULL

Hi, I have a problem with lwip in my embedded application, I'm using FreeRTOS 7.6.0 with lwip 1.4.1, I'm using lwip driver from ASF, lwip-port-1.4.0. I have three threads, which uses lwip sockets, one creates UDP socket, two TCP sockets. If I connect to my board via UDP, everything fine, but if

Re: [lwip-users] LWIP_ASSERT

HI, Well this is what I think. But I wonder if assert are handled correctly in the stack ? From what I see, nothing break when the assert happen. I do not need to restart anything to get the stack continue after the cable was reconnected to my router. Le 2014-02-12 13:12, Martin Velek a é
