Cpu_Interrupt while using Processor expert 52221DEMO

AnteOO — Tue, 27 Apr 2010 17:27:07 GMT

Hi guys!

I'm having a problem which confuses me. I'm using CW 7.2 with a 52221DEMO, and when using Processor expert to enable interrupts from my UART0, and I try to send something, I get a Cpu_Interrupt. I wonder if it's just that Processor expert forgets to update the Exception Vector Table? Is there a quick fix for this?

Bests,

Andreas

Hello,

could you please check that all beans within your project have unigue level and priority wihtin this level? I am guessing it could be the reason of your problem.

Regretfully, it didn't solve my problem...i still get a Cpu_Interrupt every time a character has been sent...Tried to check why it comes to that, but cannot find anyting. Attatching my project if anyone wants to take a look

Hello,

as i wrote in my previous post - you must ensure that all beans within your porject have unige level and priority within this level. To avoid receiving unhandled interrupt I just swicthed "Interrupt priority" property in TimerInt bean to another value than "level 3, priority witin level0" (that is already set in Asynchroserial bean). I have also corrected your project.

For more details please see chapter "13.3.6 Interrupt Control Registers (ICRnx)" in reference manual of M52221 MCU.
