Green Hills AdaMulti for MPC5554

jagannathamb — Sat, 09 Nov 2013 02:11:18 GMT

I am using Green Hills AdaMulti for s/w development targeted to MPC5554. My application needs one 10 msec interrupt. Upon each interrupt it needs to execute some procedure ( which is computation intensive) and after finishing it has to wait for the interrupt.

I used the FIT Interrupt for 10 msec interrupt generation.

2. In FIT ISR i called the myprocedure().

But it runs for some time and stops.

My Code Structure looks like this.

procedure Adamain

begin

loop

I/O Reading Procedures.

end loop

end

and In FIT ISR

FITISR()

{

Serivice the Interrupt

executive(); // this is a my application which is compute intesive.

}

can anyone help me out.

Hi,

there's code example in AN2865 for the FIT:

MPC5500 and MPC5600 Simple Cookbook Code

The FIT exception handler should store all volatile registers (given by EABI standard) to stack and reloaded them at the end of handler. Take a look at file:

AN2865SW.zip\AN2865SW_rev4\555x-CW\FIT\src\handlers.s

and

AN2865SW.zip\AN2865SW_rev4\555x-CW\FIT\src\main.c
