Cpu_Interrupt while using Processor expert 52221DEMO

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,

 

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.

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.
