Re: [ECOS] PowerPC FEC interrupt handler problem

["Khasim" <khasim at iwavesystems dot com>]

Hi .
Thanks for your kind responce. I have one more doudbt

See When an interrupt comes the control should go to 0x500 location and then
it has to branch to the appropriate handler based on the interrupt.

I dont find any such code which is doing this . Please tell me how interrupt
handler registration is done here.
I saw the function  cyg_drv_interrupt_create

Which is creating an interrupt object but how this will be used when an
interrupt occurs.

What all parts of the code I need to change If I have to incorparate the
changes required for my board compared to viper board.

Thanks in anticipation

Khasim
