Hi, I am trying to use the lwIP demo for the SAM7x and have been getting some strange behavior. I am using FreeRTOS 4.1.3 with GCC 4.1.1 (with the -fomit-frame-pointer flag).
I have created two tasks UserTaskA and UserTaskB and added them to the lwIP_Rowley_demo example as shown according to the Webserver URL:
Task State Priority Stack #
WEBSvr R 1 25 1
IDLE R 0 84 4
lwIP B 3 338 0
UserTaskA B 2 62 2
UserTaskB B 2 68 3
Eth_INT B 4 297 5
However when I add a simple declaration,
static xQueueHandle xWebQueue
to main (see below), the WebSvr runs for about 10 page hits and then hangs due to a data abort error within tcp_in.c. Am I missing something?
static xQueueHandle xWebQueue //statement added here
sys_thread_new( … )
vStartUsertasks( … )
My goal is to pass the xWebQueue into the spawned webserver and user tasks so that they can communicate.
