[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [September 2005 Threads] Cant take off USB CDC taskPosted by Nobody/Anonymous on September 3, 2005 When I remove the line that creates the USB task from the lwIP project - the next time I compile and run I get a data abort exception. How can not creating the USB task cause an exception?
RE: Cant take off USB CDC taskPosted by Richard on September 3, 2005 Have you removed the idle task hook that writes to the USB port? If you don't initialise the USB port but try to write to it, it could well crash.
Remove the line vUSBSendByte( cTxByte );
from the function vApplicationIdleHook();
define in file FreeRTOS/Demo/lwIP_Demo_Rowley_ARM7/main.c
