How to resolve ipc1 task

ipc1,ipc0 tasks are auxiliary tasks used during flash operations. If code on CPU0 is doing flash operation, then ipc1 task runs for the duration of the operation; and vice versa. In the log you have posted, it says that IDLE task on CPU0 has not been running for a while. It means that the task on CPU0 did not yield to IDLE task for that duration of time. Ipc1 task is running on CPU1, so it is not itself responsible for the problem. It just happens to be running on CPU1 at the moment when the task watchdog is printing this message.
