Hi,

I am using EVM from logic PD with som C6748 on it.We are using BIOS.But we are unable to get interrupt.We are using CCS4.1,BIOS version is 5.41

 

We have made the following changes in the .tcf file

bios.HWI.instance("HWI_INT4").interruptSelectNumber = 63;//RTC interrupt

bios.HWI.instance("HWI_INT4").fxn = prog.extern("interrupt4", "asm");

following changes are made in the dispatcher.

bios.HWI.instance("HWI_INT4").useDispatcher = 1;

Even though interrupt is configured for one minute,unable to get the interrupt

But one more work space is created without using BIOS.

but we are getting interrupt .(RTC Interrupt).

Pls help me where we are missing.
