Few questions...
1. Have U built up your own H/w setup ?
2. What all other devices are using interrupts on GPIO pins ?
3. Is their any driver other than TIWLAN getting inserted at runtime which user
GPIO interrupts ?
4. If 3 is true then that driver might not be configuring GPIO interrupt
properly.

Hi,
I am working with tiwlan in Davinci EVM(DM6446)
Once i reset the tiwlan i am getting interrupt.Interrupt is connected to
GPIO18
But after some time at CMD_ENABLE_RX interrupt goes low and it shows a big
exception
If anybady has similar problem or any experience with tiwlan please suggest
me.
I am getting the below said debug message.Please suggest us
