IRQ Interrupt

[polofermin]

Hello,

I am new in CodeWarrior:

-I am targeting with MCF51EM256 CPU

-My version of CodeWarrior is: Codewarrior IDE version 5.9.0 Build 2830

I´m programming with FreeRTOS kernel and I use IRQ interrupt. I don´t have any problem with linker, but when I simulate the program entry for once in the IRQ interrupts and it doesn´t entry again (also I erase IRQ flag to entry in the interrupt)

any idea?

Thanks so much..

Best regards

Hi,

It will be better if you can be more descriptive.

Is it a sample code you are running, or your custom application....

Which target are you running??....SDRAM/SRAM/ROM??

What do you mean by simulating program entry??

Also it will be better if you can  post your

1. LInker.

2. CFG file

3. vector.s file...

because, if it is a start-up problem, 

these are the popular suspects...

Regards,

Venki

I already know why the interrupt was not working ... I was erasing the IRQ settings register, and I just had to clear the ACK bit (only)...thank so much

BYe!

Best regards and merry christmas
