_int_unexpected_isr

Question asked by Terry Buckley on May 26, 2011

1. has anybody rewritten (int_unx.c) to use some type of raw serial so that it will work with interrupt serial (ittyx) instead of just polled (ttyx).

 

2. Is there a document describing the data you get from _int_unexpected_isr to help determine the problem.

 

3. Spent about 3 hours yesterday in _int_unexpected_isr because of a gpio_ioctl(read) on a const GPIO_PIN_STRUCT, the const made the structure end up in read only memory and gpio_ioctl(read) caused access to read only memory and that is how I ended up in _int_unexpected_isr

 

cheers,
