Hi,
Am working on the ARM on OMAP 1510 Innovator board. When I step over
a function the code hangs. On halting the processor it ends up on
undefined instruction interrupt. However on stepping through the same
function it executes the code and I can come out of the function
properly.
This happens most of the time, though not all times.
Stack size is set at 2000. Increasing it did not change the behaviour.
Why is this happening ?
What should be done to recify this ?
kindly reply,
rmb
Undefined Instruction Interrupt on ARM OMAP 1510

hi,
Ensure that the board is not generating unwanted interrupts.
Looks like the processor is getting interrupts and it is trying to branch to the service routine. You may not observe this when you single step as the processor may not be running for a sufficient time for the interrupt to occur and the processor to respond.
