hello all,
I am using LPC2292, GCC Compiler.
I am writing code which should handle nested interrupts.
Watchdog is enable and default handler is also written properly (all
interrupts are handled over here).
My problem is:
After 3-4 hours sucessfull transmission and reception of frames,UART
transmit interrupt is missed and unit gets hanged.
I think it is the problem related to nested interrupt handling or
some thing is missing in default handler.
I used the following interrupts:
External Interrupt
Timer 0 and 1
UART 0
Watchdog
Please tell what must be the problem,which is occuring after 3-4 hr.
sucessful operation??
Thanks,
Priya
